Why Me?

This is a blog about Desulfurization technology, and so you will see that this post is somewhat off-topic … but I think it is relevant, so here it is …

A company I used to work for implemented a rewards program to support their subscription to the “Balanced Scorecard” theory. One of their reward categories was “cost savings.” Periodically, the president of the company, with much fanfare, congratulated the winner of the “cost savings” initiative. The lucky recipient of the award won a $100 bonus check.

On one such occasion it occurred to me that I could suggest something that would save the company a LOT of money … just go out of business! That would save TONS of money! Fortunately. my inner voice told me that this would (A) not result in a prize and (B) would result in the loss of my job. So I said nothing.

And now to my point … any successful businessman knows that SAVING money is not why he is in business. He is in business to MAKE money. To MAKE money, you need to use your available resources in the most effective way to maximize profit.

If your business employs highly skilled, and therefore highly paid, scientists and engineers, to MAKE money you need to be sure that their time is engaged in the pursuit of science and engineering … NOT in Googling for the information that they need to pursue the science and engineering that makes you money.

That is why you …
(A) Employ a librarian to support your scientists and engineers, OR …
(B) Engage the services of an Independent Information Professional like Jean Steinhardt Consulting LLC

If you do, you will save money … but you will save money STRATEGICALLY.

P.S. The company in question no longer exists. It was acquired as part of a strategic realignment by another company (AECOM) which seems to understand the concept of making money.

Frontiers of Chemical Engineering in China

Thousands of brilliant minds are working on solutions to the technological problems that confront modern civilization. And the brilliance emanates from sources across the globe. For example …

Frontiers of Chemical Engineering in China, 2009, 3(1): 12-19
DOI 10.1007/s11705-009-0151-3
Measurement and correlation of supercritical CO2 and ionic liquid systems for design of advanced unit operations
Hiroshi Machida et al
Department of Chemical Engineering, Research Center of Supercritical Fluid Technology, Tohoku University, Sendai, Japan

"Ionic liquids combined with supercritical fluid technology hold great promise as working solvents for developing compact processes. Ionic liquids, which are organic molten salts, typically have extremely low volatility and high functionality, but possess high viscosities, surface tensions and low diffusion coefficients, which can limit their applicability. CO2, on the other hand, expecially in its supercritical state, is a green solvent that can be used advantageously when combined with the ionic liquid to provide viscosity and surface tension reduction and to promote mass transfer.

"In this work we examine a subset of of available high pressure pure component ionic liquid PVT data and high pressure CO2-ionic liquid solubility data and report new correlations for CO2-ionic liquid systems with equations of state that have some industrial applications including:
(1) general
(2) fuel desulfurization
(3) CO2 capture
(4) chiral separation"

By the way, if you have ever wondered what the “DOI” designation stands for, it signifies “Digital Object Identifier.” It is a way to uniquely identify each discrete item on the Web, making it easier to cite and find. For example, the DOI for the article above is DOI 10.1007/s11705-009-0151-3. To find your way to the article on Google®, you could search by its title, or you could search by its DOI. Advantage? Usually the DOI search will result in just a handful of highly targeted search results, reducing your browsing time.

The Catalyst Review Newsletter

According to its website (http://www.catalystgrp.com/catalystreview.html) …

The Catalyst Review is a monthly newsletter specially geared for a targeted, busy audience...people who need to stay on top of developments that can affect their business, but don't have a lot of time to do that.

“The Catalyst Review is designed to provide readers with a global overview of events impacting the $10 billion catalyst industry, through selected abstracts, company interviews, and original articles. There is also a special "Rumors" column that gives a view of what's going on behind the scenes too. Reader questions and comments are welcomed, to provide an additional value to subscribers. This reinforces the purpose of The Catalyst Review, which is to provide a timely line on key news and research, in an easy-to-digest format.”


We do not subscribe, but found a sample letter online that looked good (see below), so you might want to take a look.

“The Catalyst Review Newsletter, Special Feature
“Catalysts for Hydroprocessing Heavy Oil
“The development and use of technologies for hydroprocessing of heavy oils have been receiving attention because of the decrease in the amount of light sweet crude oil available for refineries. The imbalance created by the increasing demand for distillate products can only be solved by increasing the upgrading of heavy and residual oils. This favors investment in the development of catalysts for heavy oil conversion and upgrading.

“Of the available possibilities for treatment of heavy oil, hydrogen addition processes lead not only to overall higher liquid yields but also high hydrogen consumption. These processes, which provide the feedstock for the subsequent fluid catalytic cracking, require the use of well designed catalysts capable of dealing with the high concentrations of metals and asphaltene constituents in the feedstock. Moreover, the multifunctional catalysts used for hydrocracking processes (Figure 1) become poisoned by coke deposition and the heavy metals present in the feed create a hazardous waste, which has to be disposed properly. A high catalyst demetallization function is necessary and the concentration of nitrogen compounds must be taken to a minimum to avoid poisoning of the catalyst acid sites in subsequent processes."

The entire article is worth reading, but the following observation caught my eye …

"Due to high worldwide demand, getting the necessary equipment delivered to the site could be a major challenge for any project. Construction and installation schedules are often governed by the delivery of long-lead items."

“Estimated equipment/materials delivery matrix
Compressors (reciprocating)...70-92 weeks
Compressors (centrifugal)...70-84 weeks
ANSI pumps..................22-30 weeks
Reactors (ULSD/alloy)........18-24 months

PUBMED: A Surprising Resource

A name like “PUBMED” suggests medical research … and that is largely true. PubMed Central (PMC) (http://www.pubmedcentral.nih.gov/) is the U.S. National Institutes of Health (NIH) free digital archive of biomedical and life sciences journal literature. But it also contains a surprisingly large number of articles relating to desulfurization. It is free, and it is worth a look. Although most are abstracts only, a number are available in full text, e.g., the following review …

Abstract
Aromatic compounds are among the most prevalent and persistent pollutants in the environment. Petroleum-contaminated soil and sediment commonly contain a mixture of polycyclic aromatic hydrocarbons (PAHs) and heterocyclic aromatics. Aromatics derived from industrial activities often have functional groups such as alkyls, halogens and nitro groups. Biodegradation is a major mechanism of removal of organic pollutants from a contaminated site. This review focuses on bacterial degradation pathways of selected aromatic compounds. Catabolic pathways of naphthalene, fluorene, phenanthrene, fluoranthene, pyrene, and benzo[a]pyrene are described in detail. Bacterial catabolism of the heterocycles dibenzofuran, carbazole, dibenzothiophene, and dibenzodioxin is discussed. Bacterial catabolism of alkylated PAHs is summarized, followed by a brief discussion of proteomics and metabolomics as powerful tools for elucidation of biodegradation mechanisms.

Biodegradation is a very broad field and involves uses of a wide range of microorganisms to break chemical bonds. It has been well reviewed [1, 2], however, it is a very active field and new data are rapidly contributed to the literature. This review is focused on bacterial catabolic pathways of selected aromatic pollutants under aerobic culture conditions (Table 1). The selected aromatic pollutants include the PAHs naphthalene, fluorene, phenanthrene, fluoranthene, pyrene, and benzo[a]pyrene, the heterocycles dibenzofuran, carbazole, dibenzothiophene, and dibenzodioxin, and alkylated PAHs. Metabolomics and proteomics in elucidation of mechanisms of microbial degradation of aromatics are also briefly discussed.

Symposium FC
Fuel Cells: Materials and Technology Challenges
Advisory Board
Invited Lectures

Deteriorating urban air-quality, growing dependence on insecure energy sources, and global warming are forcing the re-examination of conventional energy conversion systems throughout the world. Although new combustion technologies emit far less toxic pollutants comprising hydrocarbons, nitrogen oxides, carbon mono-oxide and particulates than in the past, the increasing energy demand is resulting in growing insistence to reduce pollution. At present, motor vehicles account for about one-half of the total hydrocarbon and nitrogen oxide pollution which combine to form ground-level ozone, commonly known as smog, that chokes many of the major urban centers of the world. However, the pollution level is also significantly influenced by stationary energy generation plants. This has brought in emission legislation all over the world, particularly in the light of the Kyoto Protocol, requiring the introduction of new energy conversion technologies and zero-emission vehicles. Among the various available electrochemical energy conversion systems fuel cell technology represents one of the most viable candidate solution to these drawbacks.
Fuel cells deliver energy at high efficiency by consuming electroactive chemicals that are supplied on-demand to the cell as in a conventional thermal combustion system.

The International Symposium “Fuel Cells: Materials and Technology Challenges”, through the contribution of experiences coming from several different disciplines, will focus major advances in materials science, processing and device manufacturing of the different fuel cell categories.

Original papers are solicited on all types of fuel cells. Of particular interest are recent developments of advanced fuel cell materials, novel fuel cell stack designs, emerging fuel cell technology, and optimization and breakthroughs in performance. Reviews of the state-of-the-art fuel cell performance for specific applications, including consumer devices, electric vehicles, and distributed energy systems, may also be submitted.

Contributions are invited in the following and related areas:

FC-1 Solid Oxide Fuel Cells (SOFCs)

Intermediate temperature solid oxide fuel cells
Direct conversion of organic fuels in solid oxide fuel cells
Mixed reactant and single chamber SOFCs
Materials issues in solid oxide fuel cells
Demonstration of SOFC plants
FC-2 Polymer Electrolyte Fuel Cells (PEFCs)

PEFC stacks for automotive application

Commercial Break: Thesis on Biodesulfurization

The thing about biodesulfurization is … it’s not cost effective. That is the issue addressed by this thesis, which is why it may be useful.

Sulfur-selective biodesulfurization of organosulfur compounds in model oils and distillate fractions
Thesis
Jantana Tangaromsuk
Mahidol University (2007)

“Biodesulfurization is an attractive method considered to be an alternative or complementary to hydrodesulfurization, helping refiners to cost-effectively meet new sulfur regulations. Over past decades, this technology has been investigated aggressively, but it has not yet been successfully commercialized. One problem is the cost of biocatalysts. To reduce the cost, microorganisms with sufficiently high activity and wide substrate specificity should be developed. The aims of this study were to isolate and select the desulfurizing microorganisms with high activity and broad substrate specificity, and to investigate mass production biocatalysts with high activity, which has the potential to reduce overall biocatalyst cost.

“In this study, bacteria, which could utilize organosulfur compounds as a sulfur source, were isolated from oil sludge and soil samples. DBT desulfurization activities of isolated strains were conducted. The strains with high activity were selected and identified by 16s rRNA sequencing. These strains were further studied for their substrate specificity by investigating the growth of the bacteria on various organosulfur compounds (i.e., BT, DBT, 3,4-benzoDBT, 4,6-DMDBT, methyl phenyl sulfide, phenyl sulfide and phenyl disulfide.) Biodesulfurization of these substrates by growing and resting cells of the bacteria was also conducted. In addition, biodesulfurization of crude oil and hydrodesulfurized diesel oil by the selected strain was also investigated.”

Google® Scholar Revisited

The dual purpose of this blog is to highlight resources we have found, and to offer tips you can use to make your own searches more effective. Today we revisit Google® Scholar. Google® Scholar has much to recommend it. In addition to its focus on scholarly articles, it also shows the number of times a given article has been cited by other scholarly articles. The cite number is one way to gauge the significance of particular work, as judged by the author’s peers.

For example, a recent search using the search string ...

The Internet ... ya gotta love it! (BioCyc.org)

The things you stumble over in the dark can be mind-bending. Take a look at BioCyc.org (http://biocyc.org/)

"Introduction to BioCyc
"The BioCyc collection of Pathway/Genome Databases (PGDBs) provides electronic reference sources on the pathways and genomes of different organisms. The databases (DBs) within the BioCyc collection are organized into tiers according to the amount of manual review and updating they have received.
"Tier 1 PGDBs have been created through intensive manual efforts, and receive continuous updating [details of Tier 1]. The BioCyc Tier 1 DBs are EcoCyc (Escherichia coli K-12) and MetaCyc (experimentally elucidated enzymes and metabolic pathways from more than 1,500 organisms.)
"Tier 2 PGDBs were computationally generated by the PathoLogic program, and have undergone moderate amounts of review and updating. [details of Tier 2]
"Tier 3 PGDBs were computationally generated by the PathoLogic program, and have undergone no review and updating. There are 482 DBs in Tier 3. [details of Tier 3]

"Looking for pathway databases for other organisms? PGDBs have been created outside SRI for many organisms [details].
"BioCyc Tools
"Scientists can use the BioCyc Web site to visualize individual metabolic pathways, or to view the complete metabolic map of an organism [example]. The latter diagram can be used to analyze gene expression, proteomics, or metabolomics data using the Omics Viewers, such as to produce animated views of time-course gene-expression experiments [example]. The BioCyc Web site also provides genome browsing capabilities [example], and for the EcoCyc DB in particular, provides extensive information about transcriptional mechanisms of gene regulation [example]. BioCyc also provides comparative analysis tools (see Tools -> Comparative Analysis in the toolbar)"

“NanoActive materials are metal oxide aggregates that possess very large surface areas, defect-rich morphology, large porosities, and small crystallite sizes. This combination of properties results in extremely high reactivity including both enhanced reaction kinetics and large capacities. These materials have shown utility in both consumer and military applications. Of particular importance is the destructive adsorption of various toxic and odorous compounds, air and water filtration, as well as removal of heavy metals and sulfur species. In addition, novel metal oxide formulations with the unique ability to neutralize toxic chemicals as well as biological organisms were developed. Several of oxides have been shown to possess considerable biocidal activity against the opportunistic pathogens Staphylococcus aureus and Pseudomonas aeruginosa with applications in antimicrobial paints and coatings. Consumer products based on these materials include chemical spill control systems and odor neutralization systems.”
