“Religion is the everlasting dialogue between humanity and God. Art is its soliloquy.” -- Franz Werfel (German Expressionist Poet, Playwright and Novelist. 1890-1945)

Among librarians and other information professionals, the Dialog family of databases represents the gold standard for online research. The range of subjects covered by the Dialog databases is huge. The depth of content in each database is staggering. And the power of its search engine is extraordinary.
That said, because it is a fee-based database system, it is easy to run up big bills while achieving tiny results. That is why, in most organizations, access to Dialog is restricted to seasoned information professionals.
However, if your company subscribes to Dialog but does not employ a librarian, you can still search it effectively … if you are careful.
Dialog has addressed the problem in myriad ways. It offers menu-driven interfaces for the beginner. It offers a command line interface for the expert. And it provides lots of documentation.
Here is a brief on some of the documentation …

Introduction to Dialog®
The Dialog service is the world's most comprehensive online information retrieval service and has been serving users since 1972. With over 600 databases from a broad range of disciplines, Dialog provides international access to information in a broad scope of subject areas. The volume of data available combined with the system's searching capabilities make Dialog the largest and most powerful online service of its type.
The Dialog content collection contains hundreds of databases comprised of millions of documents drawn from a multitude of sources. Dialog brings you scientific and technical literature; full-text trade journals, newspapers and newswires; details on millions of chemical substances; information on patents and trademarks issued worldwide; demographic data; and company financial statistics.
About the Dialog Command Language
A variety of interfaces are available for accessing Dialog. Web-based, fill-in-the-blanks products such as DialogSelect™ and DialogPRO are intended to meet the needs of knowledge workers who are not information professionals. Among information professionals, the Dialog Command Language, present in products such as DialogLink 5® and DialogClassic Web™, continues to be favored by professional researchers. It offers sophisticated search options, precision search and retrieval tools, and a host of unique features. With Dialog Command Language, the researcher has complete control over which databases are interrogated and how the search is executed; exactly what data elements are retrieved and how they are output.
Dialog Command Language is an integral feature in the following product interfaces. Use any to mine more than 600 databases containing comprehensive, authoritative sources of scientific, technical, medical, business, news and intellectual property information:
DialogLink 5 is a powerful Windows®-based software tool that greatly extents the functionality of Dialog Command Language, especially in the areas of search management and post-processing of search results. The most recent versions of DialogLink use DialogAPI technology to enable Web-based functionality lacking in the traditional DialogClassic, text-only interface. Examples of such features include:
output in XML, HTML, PDF and RTF
report output to native Microsoft to Word and Excel formats
graphical, template-based interface to many commands
enhanced functionality for DIALINDEX and Alerts
hyperlinking to electronic documents and journals
DialogClassic Web™ offers most of the sophisticated search capabilities of DialogLink 5 in a browser-based interface via the Web.
Dialog®Web offers two ways to search: via Guided Search and Command mode. Command mode supports Dialog Command Language delivering the power and precision of DialogClassic through a Web browser. Many command shortcuts are available via graphical icons and check-box selection.
DialogClassic offers a command-driven, text-only, line-oriented interface for search and retrieval at extraordinary speed. This is a fast and highly flexible interface for power searchers.
Dialog Without Command Language
Other Web-based interfaces are available for searching Dialog that exploit the features of HTML and Web scripting to simplify the search experience and do not use Dialog Command Language. The following have been created for researchers more familiar with Web search engines. Each of these interfaces represents an off-the-shelf solution built atop the core Dialog system. Each offers simple fill-in-the-blanks templates for search and retrieval.
DialogSelect™ allows you to get complete information without needing to know which sources to search or how to search them.
DialogWeb offers two ways to search: via Guided Search and Command mode. Use Guided Search mode for full access to the Dialog system through a flexible and easy-to-use Web-based interface that does not require knowledge of commands.
DialogPRO is a subscription-based service ideal for small business researchers.
More recently, new tools enable customers to exploit the power of Dialog Command Language by creating customized interfaces to the Dialog system.
Dialog API is an application tool that supports Web Services Description Language (WSDL) and Simple Object Access Protocol (SOAP) for integrating Dialog content into compatible platforms.
Dialog Intranet Toolkit provides a suite of search forms for building a targeted information query and delivery service into an organization's intranet.
Custom Solutions provides an opportunity to deliver Dialog content to your own internal systems, or to have Thomson Scientific develop a solution tailored to your specific organizational needs.

Dialog Command Language Search Basics
A search using Dialog Command Language can be as simple as typing a few words of text, or it can incorporate an array of search features and commands that can enhance both the search process and the final search results. Every search involves an interaction between you and the search engine — a “dialog.” This Basics section describes how to enter commands, put searches together using operators, display output and use special techniques for numeric and range searching.

Dialog Bluesheets
Bluesheets are written guides for every database on the Dialog® service. They contain detailed instructions on search techniques for the special features of each database, including file description, subject coverage, date range, update frequency, sources of the data, and the origin of the information. On the Bluesheet you will also find a sample record that shows what you can expect to obtain when you perform a search in the database.
The most important part of the Bluesheet, however, is the Search Options section. Here you see the field labels that you can use to focus or narrow your search, as well as examples of how to use them online. Bluesheets on the Web are updated regularly and reflect the most current database information available.They also contain up-to-date rates information.

///////
Introducing the new Theme Director for the Schlumberger heavy oil initiative
We are delighted to announce the appointment of a new Theme Director for the Schlumberger heavy oil initiative. Kambiz Safinya has taken over the role from Jorge Lopez de Cardenas who is now leading a number of new assignments.
Dr Safinya has been with Schlumberger for more than 26 years in a variety of technical, research, marketing and management roles. He holds a Bachelor's degree in mathematics and physics from Bates College, Maine, USA, and both a Master's and Doctorate in physics from Harvard University, Massachusetts, USA.
His career with Schlumberger has taken him from the USA to Asia, and from the Middle East to Europe, with assignments ranging from research and development in wireline logging to electromagnetic equipment design, and from operations management and marketing to the integration of electromagnetic and seismic measurements.
"Heavy oil reservoir development presents a number of significant technical challenges that require much communication between reservoir experts and technology developers," observes Dr Safinya. " In this respect, heavyoilinfo.com has become an industry channel to share experience, and one that I believe will add considerable value to sharing knowledge. I look forward to my involvement."

Technology Alert: Google Alerts
"Love is like pi - natural, irrational, and very important.” -- Lisa Hoffman
The following article, interesting though it may be, is not the point of this post. The point is the usefulness of setting Google Alerts.
The key to avoiding information overload is to make the alert tightly focused. This article, for example, resulted from a Google Alert on π-complexation … a term often associated with desulfurization research, but which retrieves far fewer results. And of those, many of them will be relevant to your research interests.
Pick through your stash of articles for key words and concepts specific to your needs. Then Google® them and, based on the results, create Google Alerts using the most promising key words in your list.

Abstract
Reactive adsorption desulfurization of FCC gasoline over a Ni/ZnO−SiO2−Al2O3 adsorbent was carried out in a fixed-fluidized bed reactor at low pressures in the presence of hydrogen. The results show that high temperature, high pressure, high molar ratios of hydrogen-to-oil, and low weight hourly space velocity are favorable to improve the desulfurization ability of adsorbent but not conducive to maintaining the octane number of FCC gasoline throughout the condition range examined. Under optimal operating conditions, ultralow sulfur gasoline can be produced, and the RON loss is only 1 unit. Furthermore, the effect of prereduction and adsorbent characterization data (SEM/EDX, N2 adsorption) reveal that reduction increases the interaction between Ni and S compounds and improves the pore structure of adsorbent, leading to a significant improvement in the desulfurization capability of adsorbent. Take 3-methylthiophene for example, after adsorbing on an active Ni atom via the S−Ni bond, the sulfur of 3-methylthiophene is removed by direct hydrogenolysis of the C−S bond, resulting in the formation of NiSx and 2-methyl-1,3-butadiene in hydrogen atmosphere. The latter is mainly hydrogenated to 2-methyl-2-butene and 2-methylbutane. ZnO acts as a sulfur-acceptor, which can regenerate the active Ni in situ in hydrogen atmosphere. The complete sulfidation of adsorbent particles takes place by ion diffusion.

Conference Alert: Sulfur 2010
“The tragedy of modern man is not that he knows less and less about the meaning of his own life, but that it bothers him less and less.” --Vaclav Havel (Czech Playwright and President of Czechoslovakia (1989-92), b.1936)
“I find myself fascinating.” -- Milan Kundera (Czech Novelist, Playwright and Poet, b.1929)
Sulfur 2010 International Conference & Exhibition (www.sulphurconference.com) 1-4 November 2010, Prague Hilton, Czech Republic is worth noting. For one thing, when you desulfurize petroleum, you need to have a plan for what to do with the sulfur. Beyond that, the Sulfur Conference includes papers and presentations on technologies and techniques being used to desulfurize petroleum and other hydrocarbon materials.
Quoting from the conference brochure ...
///////
“For decades the sulphur market has appeared to be on the brink of major, long-term structural oversupply as vast new sour gas and oil projects have become due to come into operation in many parts of the world, but somehow, owing to a combination of construction delays, logistical constraints and unexpected demand, this never yet seems to have happened on a lasting basis. Indeed, two years ago the price of sulphur on the world market rose, albeit briefl y, to a level that was not merely unprecedented but entirely unimaginable.
“Recent events in the Gulf of Mexico appear to have finally sparked a change in political attitude in one of the world’s main energy-consuming economies towards the continued unchecked growth in demand for crude oil. Could it have lasting repercussions further afield? Will the shift towards sources of energy that do not produce sulphur, such as nuclear power and biofuels, now accelerate, and what is its effect on the balance of the sulphur market likely to be? Will biofuels genuinely displace fossil hydrocarbons or will their effect be cancelled out by the extra demand for fossil feedstocks to produce the fertilizer needed to grow them?
“Sulphur 2010 will keep you up to date with the state of the market for sulphur and sulphuric acid and provide you with the underlying industrial trends affecting its balance and direction.
“After a day of commercial grounding, Sulphur 2010 will dedicate two days to examining developments in the technology and operation of sulphur and sulphuric acid production, logistical and environmental facilities.
Delegates will also benefi t from visiting exhibits from over 45 companies serving the sulphur and sulphuric acid industry. New this year is the a pre-conference seminar on the Amine Treating for Sulphur Recovery.”

Theoretical study of the catalytic desulfurization mechanism of thiiren and its methyl derivative
J.B. Mensah, Y.G. S. Atohoun, L.O. Olatunji
Abstract
The desulfurization process of compounds implicates two steps. The first step is the adsorption process on the catalytic site and the second, the
breaking of the carbon-heteroatom bond leading to the heteroatom elimination. The adsorption process of thiiren have been studied and published in
previous works. The results obtained on MoS3H3+ and MoS4H4 have shown that the adsorption of this molecule was very good on the two and three anionic
vacancies sites based on molybdenum. In the present study, we have carried out the adsorption according to vertical and horizontal geometries of
dihydrothiiren, methylthiiren, and methyldihydrothiiren, and the desulfurization of all these molecules including thiiren molecule. The results obtained
have shown that, the desulfurization of thiiren and its methyl derivate pass through the hydrogenation of the aromatic ring on the two types of catalytic
sites.

Title: The Effect of γ-Al2O3, TiO2 and ZrO2 Supports on Hydrodesulfurization Activity of Transition-Metal Sulfides
Creators: Kaluža, Luděk

Abstract
The transition metals V, Cr, Mn, Fe, Co, Ni, Mo, Ru, Rh, Pd, W, Re, Os, Ir and Pt were deposited from aqueous solutions of their salts onto conventional
γ-Al2O3 and unconventional TiO2 and ZrO2 supports by vacuum impregnation and characterized in their sulfided
form by a model reaction of benzothiophene hydrodesulfurization. It was found that the TiO2 and ZrO2 supports influenced
predominantly positively the resulting activity of relatively low-active metals (V, Cr, Mn, Fe, Co, Ni, Mo, Ru, W and Os), whereas the highly active
metals (Rh, Pd, Ir, Pt and Re) were influenced slightly negatively or not at all by those supports compared with the γ-Al2O3-
supported system. A significant effect of the supports on the hydrodesulfurization-activity ranking of the transition-metal sulfides studied was
ascertained.

Abstract
We present density functional theory (DFT) calculations of the hydrogenation (HYD) and direct desulfurization (DDS) pathways of thiophene
hydrodesulfurization (HDS) over cobalt-promoted MoS2. We find that the Co–Mo–S edge in its equilibrium state under HDS conditions is reactive toward both
hydrogenation and C–S bond scission without the initial creation of vacancies. This can be accomplished such that additional S is bound to the Co–Mo–S
subsequent to C–S bond scission and then removed in the final reaction step. We find thus that coordinatively unsaturated sites (CUS) are present in the
equilibrium structure, and at these sites HDS can take place without sulfur removal in the first step. No traditional vacancies are formed and the
present mechanism is therefore very different from the previously proposed vacancy mechanisms requiring the initial creation of a sulfur vacancy for the
reaction to proceed. We find that Co-promotion decreases the barrier of hydrogenation reactions and active site regeneration but increases the barrier of
C–S-scission reactions. The net result of Co promotion is found to be an increase in the hydrogenation activity and also of the relative importance of
the DDS pathway. We compare our results to available experimental information and find a number of consistencies and parallels. Therefore, we can
rationalize the promoting effect of Co such that at the Co–Mo–S edge, good hydrogenation properties are combined with the ability to bind additional
sulfur upon C–S-scission. Finally, we propose that the interactions between the Co-promoted S-edge and the non-promoted Mo-edge may play a role in the
hydrogenation pathway.

Rhodococcus erythropolis N1-36, a desulfurization strain, was grown in continuous culture at 10 different dilution rates with 50 (mu)M dibenzothiophene
sulfone (DBTO(inf2)) as the growth-limiting nutrient. The steady-state biomass, concentrations of substrate (DBTO(inf2)) and product
(monohydroxybiphenyl), saturation constant (0.39 (mu)M DBTO(inf2)), and cell yield coefficient (9 mg of biomass(middot)(mu)M(sup-1) DBTO(inf2)) were
measured. Continuous cultures at five temperatures allowed calculation of activation energy (0.84 kcal(middot)mol(sup-1) [ca. 3.5 kJ(middot)mol(sup-1)])
near the optimal temperature (30(deg)C) for growth. A washout technique was used to calculate the maximum specific growth rate (0.235 h(sup-1)), a value
equivalent to a minimum generation time of 2.95 h.

Abstract: A variety of microbes inhabit extreme environments. Extreme is a relative term, which is viewed compared to what is normal for human beings.
Extreme envi-ronments include high temperature, pH, pressure, salt concentration, and low temperature, pH, nutrient concentration and water availability,
and also condi-tions having high levels of radiation, harmful heavy metals and toxic compound(organic solvents). Cul-ture dependent and culture-
independent (molecular) methods have been employed for understanding the diversity of microbes in these environments. Extensive global research efforts
have revealed the novel diver-sity of extremophilic microbes. These organisms have evolved several structural and chemical adaptations, which allow them
to survive and grow in extreme en-vironments. The enzymes of these microbes, which function in extreme environments (extremozymes), have several
biotechnological applications. Antibiotics, compatible solutes and other compounds obtainable from these microbes are also finding a variety of uses.

Title: Biodiesel as a lubricity additive for ultra low sulfur diesel
Author: Subongkoj Topaiboul1 and 2,* ; Nuwong Chollacoop
Abstract: With the worldwide trend to reduce emission from diesel engines, ultra low sulfur diesel has been introduced with thesulfur concentration of
less than 10 ppm. Unfortunately, the desulfurization process inevitably reduces the lubricity of dieselfuel significantly. Alternatively, biodiesel, with
almost zero sulfur content, has been added to enhance lubricity in an ultralow sulfur diesel. This work has evaluated the effectiveness of the biodiesel
amount, sourced from palm and jatropha oil,and origin in ultra low sulfur diesel locally available in the market. Wear scar from a high-frequency
reciprocating rig isbenchmarked to the standard value (460 m) of diesel fuel lubricity. It was found that very small amount (less than 1%) ofbiodiesel
from either source significantly improves the lubricity in ultra low sulfur diesel, and the biodiesel from jatropha oilis a superior lubricity enhancer.

The Power of Research
“The attempt to combine wisdom and power has only rarely been successful and then only for a short while” -- Albert Einstein (German born American Physicist who developed the special and general theories of relativity. Nobel Prize for Physics in 1921. 1879-1955)
This post has nothing to do with desulfurization research … and it has EVERYTHING to do with desulfurization research.
In 2005 MIT-Massachusetts Institute of Technology- produced a fascinating study of the technological and economic feasibility of using thermal energy to produce a significant amount of the energy required by the U.S. The resource potential has no geographic limits. It is available in every part of the planet. The technology, for the most part, is already available. Why don’t we access this energy source now? Because to make it economically competitive with existing energy resources, a relatively small amount of R&D must be funded by government funds in order to make private funding sources comfortable with making the investments necessary to produce geothermal energy.
So how does this affect desulfurization research? It affects it in two ways …
1) To the degree that geothermal research and development is successful, it reduces the price support for conventional fuels
2) The R&D effort in geothermal emphasizes the importance of conducting desulfurization research in the most cost-effective manner possible.
What does that mean, exactly? That means …
A) You need to utilize whatever resources your organization makes available to you, including librarians and other information professionals
B) Lacking such resources, you need to urge your executive management to employ such resources.
Why? Because if you do not have information professionals on your team, you are at a competitive disadvantage to other organizations that do employ such people.
Still not convinced? Browse the following 372 page MIT report …]
The Future of Geothermal Energy: Impact of Enhanced Geothermal Systems (EGS) on the United States in the 21st Century: An assessment by an MIT-led interdisciplinary panel
This report is available on the Internet at: http://geothermal.inel.gov and http://www1.eere.energy.gov/geothermal/egs_technology.html
From the Executive Summary:
“To sum up, based on our technical and economic analysis, a reasonable investment in R&D and a proactive level of deployment in the next 10 years could make EGS a major player in supplying 10% of U.S. base-load electricity by 2050. Further, the analysis shows that the development of new EGS resources will not be limited by the size and location of the resource in the United States, and it will occur at a critical time when grid stabilization with both replacement and new base-load power will be needed. Adding the EGS option to the U.S. portfolio will reduce growth in natural gas consumption and slow the need for adding expensive natural gas facilities to handle imported liquef ied natural gas (LNG).
“Although EGS-produced commercial power currently lacks a demonstration of its capability , this can be realized in the short term with a proven application of R&D support. The potential of EGS in evolving U.S. energy markets is large and warrants a comprehensive research and demonstration effort to move this technology to commercial viability , especially as the country approaches a period when gap between demand for and generation of electricity will most affect the existing system capacity.”

Searching LexisNexis Academic Universe
“There is a theory which states that if ever for any reason anyone discovers what exactly the Universe is for and why it is here it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another that states that this has already happened.” -- Douglas Adams (British comic Writer, 1952-2001)

LexisNexis is a system of databases with a powerful search engine. As with most current subscription databases, LexisNexis provides a menu-driven search option, which can help the beginning searcher. For the more advanced searcher, it also provides a sophisticated search syntax for more efficient searching of the databases.
To make most effective use of the advanced search syntax, your first contact should be your corporate or academic librarian. If your organization does not employ such a person, your next stop should be your LexisNexis representative.
For the die hard do it yourselfer, there are other resources. Here are a couple of them, with search examples to provide some hints on how to construct your own search statements.
One of the best LexisNexis cheats I have found is the one produced by Thomas Cooper Library, University of South Carolina (http://www.sc.edu/library/libguides/lggeneral/lexisnexis.pdf).

LEXIS-NEXIS Academic Universe is a full text database and because of that you may find using the / connectors more effective than and. The following is a list of connectors and some other options for constructing searches. All of these options are only available in Guided searches (not Quick search).
atleast# restricts results to documents containing the term so many number of times the terms goes inside parentheses atleast5(terrorism)
/n The letter n stands for a number from 1 to 255. /n does not specify a word order
Example: gas /5 price - - finds gas within five or fewer words of price, regardless of which word appears first
/p Words must be in the same paragraph
/s Words must be in the same sentence
Note: The /p connector cannot be combined with the /n connector
and Both words appear anywhere in the same document or Link synonyms, alternative forms of expression and acronyms
pre/n Requires both words to appear in the document. The first word must precede the second word by n number of words. Use this connector when a different word order would change the meaning.
Example: cable pre/3 television will find cable television instead of television cable
and not Excludes documents that contain the word or phrase following it. Use this connector with caution because it can exclude relevant documents. Always use this connector at the end of your search.
Example: doctor and not malpractice - - finds the word doctor anywhere in the document, but the word malpractice cannot appear anywhere in the document
* Use the asterisk (*) to replace a letter or letters in a word. You can use more than one asterisk in a word and you can use it anywhere except as the first letter.
Examples: bernst**n finds either ei or ie spelling of the name bank*** will pick up banker and banking, but not bankrupt or bankruptcy
! Use the exclamation mark (!) to replace an infinite number of letters following a word root.
Examples: acqui! finds variations of the word acquire (acquired, acquiring, acquisitions) book! finds book or bookkeeper, but will not find book-keeper or book keeper because those are read as two separate words
singular LEXIS-NEXIS automatically searches singular, regular plural and plural possessive
and endings for search words. For example, a search on the term company will find company,
plural companies, and company’s.
When you want only the plural or singular form, use the plural or singular command singular (company) plural (aids)
caps word(s) must have one or more capital letters. Useful when researching names.
allcaps word(s) must have all capital letters. Helpful when searching acronyms.
allcaps(plural(aids))
segment When viewing a document, any header (or segment) with a bold label is searchable even if you do not find in as a pull down option from the search box.
Segments will vary across different portions of the Lexis/Nexis Academic database.
Example: To view the front page of a newspaper, it will depend how a specific newspaper names and numbers the sections. This might even change over time with the same newspaper.

The strength of LexisNexis lies in the areas of law and news. Since LexisNexis is a subscription based resource, if your organization does not provide access to LexisNexis, you are kind of stuck. However, LexisNexis does provide non-subscription access to a portion of its legal database through Lexis Web beta (http://www.lexisweb.com/)
Below are the results of a search on “dibenzothiophene.” Why, you might wonder, would you want to search a legal database for something like “dibenzothiophene?” Good question. In your capacity as a technology researcher, you might not. But what if you wanted to know what lawsuits involving “dibenzothiophene” might have occurred? In that case, LexisNexis might help.

The strength of LexisNexis lies in the areas of law and news. Since LexisNexis is a subscription based resource, if your organization does not provide access to LexisNexis, you are kind of stuck. However, LexisNexis does provide non-subscription access to a portion of its legal database through Lexis Web beta (http://www.lexisweb.com/)
Below are the results of a search on “dibenzothiophene.” Why, you might wonder, would you want to search a legal database for something like “dibenzothiophene?” Good question. In your capacity as a technology researcher, you might not. But what if you wanted to know what lawsuits involving “dibenzothiophene” might have occurred? In that case, LexisNexis might help.

The Value of Groups
“There are basically two types of people. People who accomplish things, and people who claim to have accomplished things. The first group is less crowded.” -- Mark Twain (American Humorist, Writer and Lecturer. 1835-1910)
LinkedIn membership offers many advantages. One of them lies in the many LinkedIn groups available.
The Value of LinkedIn Groups ...
1) Occasionally you learn something useful
2) You identify potential experts in specific technologies
3) You find someone who might want to join your LinkedIn network
For example, here is part of a recent discussion from the LinkedIn Petroleum Downstream group
What unit would be good alternative for Delayed Coking Unit in a refinery scheme? Feedstock is vacuum residue or slurry from FCC.

From Simion Grigor • Hi, Teymur!
In the absence of Coking Unit the best route for VR is to go into Propane De-Asphalting Unit .
If you don't have any Deasphalting Unit we can discus about how to get a second hand one, or to refurbish an existing unit into PDA, or to engineer a new one .
The Propane Deasphalted oil , getting out from the PDA Unit is the so called ‘Bright Stock’, actually an excellent quality lubricant and most valuable base oil stock that makes most of the lubricants recipes.
The PDA Unit produces good quality road bitumen, that can be used as it gets out from PDA Unit , or blended with cutting stock.
The road bitumen produced in this way is hard ,though elastic , resilient, highly resistant to Ultra-Violet aging action , highly resistant to seasonal temperature variation , etc . due to its high % in asphaltenes & maltenes and most important due to its stabile chemical formula , providing this is NOT AIR BLOWN ASPHALT , therefore does not contain oxigenated chemical components which are most susceptible for road bitumen aging.
As concerning the FCC Slurry, the best is to separate as much as you can the spent catalyst by filtering and to use the resulted heavy oil as component for FO, or alternatively to pass the Slurry to Vacuum Unit in order to recover some cracked heavy fuel oil , whilst the VR goes for rodd bitumen .
Please feel free to discus with me the above issues.
Best regards,
Simion Grigor
