“Diligence is a good thing, but taking things easy is much more restful” -- Mark Twain (American Humorist, Writer and Lecturer. 1835-1910)
An expert you may find useful is Dr. Amarjit Bakshi (abakshi@rhtgulfcoast.com), whom I found thanks to his contribution to a LinkedIn group I follow.
He has produced a number of patents, written articles for PTQ-Petroleum Technology Quarterly, Oil & Gas Journal, and Chemical Engineer, and is principal in a Texas based company named RHT-Refining Hydrocarbon Technologies (www.rhtgulfcoast.com)
As promising as all this seems, common sense dictates that you conduct some kind of background check before seriously considering a business arrangement.
Due diligence experts are available, but you can do a preliminary background check on your own, at no cost beyond your hourly rate.
Here is a checklist of free resources. You may be aware of most, if not all, but using a checklist helps you ensure a thorough check.
• Google (Miscellany)
• Google Scholar (Peer reviewed articles)
• Google Patents (Both granted and applied for)
• Obtain full text of articles (your librarian can help with this)
• Company’s Web
• LinkedIn (Read expert’s profile; note the groups he/she belongs to; is he/she connected to anyone you may know?)
• Remember to check your subscribed databases. Many organizations subscribe to LexisNexis, EbscoHost, and Dun & Bradstreet, among others
Squeeze the most value out of each item on your check list. For example, when you search for patents, study the results for …
• Inventors (associates)
• Assignee (company names)
• Abstract (key words and concepts)
• Referenced by (more associates; more company names)
Here are some results from a PRELIMINARY background check on Dr. Amarjit Bakshi.

What would be good alternative for Delayed Coking Unit in a refinery scheme? Feedstock is vacuum residue or slurry from FCC.
Teymur = 2 months ago
Dr. Amarjit Bakshi, C.Eng • Stefan you are right as one wants from conversion process is product in gasoline/diesel or gas oil to get best ROI.
But the question is what the alternative to Delayed Coking is and I guess the premise is to lower in cost than Delayed Coker.
As we all know the most competitive refinery capacity is at least 300, 000 bbls/d refinery or higher. But all the refiners do not have financing capability to build refinery for that capacity and complexity also will drive the cost up. So Refiners have to build what they can afford not based only ROI.
But I think the question s what are alternative
Dr. Amarjit Bakshi, C.Eng • REINSERTED RESPONSE
Dr. Amarjit Bakshi • Most of the alternatives have been provided above in the comments from the experts. The major requirements after that one has to do the linear programming to look at the economics of the options. Even after the economics one has to look at the constraints of the financing and debt what the corporation is comfortable with.
Based on experience if financing/debt and cost control is major criteria, it can be easily point to certain options.
The Option of SDA and RESID FCC (if existing FCC can be revamped to high coke option) is a good one based on the required product slate. Otherwise still the other options are SDA and gasified where one can produce syngas and generate power, other option is to use syn gas to onvert to valuable fuel like diesel etc.
Another option is SDA and Coking operation with new technology of Rotary kiln technology which much simpler to operate.
As regards to Flexicoking it is site specific and normally not profitable and optimum technology except in exceptional case. This technology is offered by EXXONMOBIL and mostly used by them at about 6 or 7 refineries. One license was sold to Hellenic in 2008 and could be site specific or was not evaluated properly by the Hellenic as justification was not strong for low BTU gas. This also was very expensive option.

“What would be good alternative for Delayed Coking Unit in a refinery scheme? Feedstock is vacuum residue or slurry from FCC.”
Here are the responses …
Bill Howe • A niche solution might be to produce emulsion fuel as demonstrated at Mazeikiai refinery in 2008. Very low capital cost (<$50 million) which distinguishes it from other conversion technologies which run to hundreds of millions of dollars. Works on uncut vacuum residue allowing the cutter to be recovered to the fuel pool providing value add approaching a coker without the capital risk (an all liquid product solution - no low value coke). The niche issue is about finding a sink for the emulsion fuel.
Bill Howe
Independent Consultant
Bill Howe is the Chief Executive Officer at Quadrise Fuels International, a manufacturer of oil in water emulsions from refinery vacuum residues (and heavier). Quadrise sells a low cost equivalent to conventional HFO by establishing production facilities on refiner's sites. Benefits to the refiner are the ability to sell uncut vacuum residue to Quadrise at a price in excess of its intrinsic value as a fuel oil component; where its value is diminished by the need to add high value cutter-stock for viscosity control. Mr. Howe has more than 32 years of experience in the natural resources industry. Prior he was an Executive Director of Oil, Gas, and Energy at Bateman Projects, an EPC contractor; where he was responsible globally for oil, gas, water, and energy contracting operations. Mr. Howe has also worked as Director of Sales and Marketing at Foster Wheeler Energy Limited, an EPC contractor. He is knowledgeable on all commercial facets of the EPC contracting business and has specific experience around power generation, oil refining, GTL, residue emulsion fuel and water and waste engineering operations. Mr. Howe has knowledge on the process industries in South Africa where he was Managing Director of Foster Wheeler's local affiliate.

Ron Wright
I think the answer would depend on what products you are trying to maximize and the quality of the vacuum resid you are working with. In general, you have carbon removal (delayed coking, resid FCC, visbreaking, solvent deashpalting) or hydrogen addition (Resid hydrotreating/hydrocracking ) options. They all have their place depending on the situation.
Ron
Rob Wong
One other to consider, in addition to Ron's excellent suggestions, is a fluid coker. However, you need to have a ready disposition for the byproduct low BTU gas.
Roger Haglund
Depends what product you are primarly interested in, and what Capext you can carry
For a diesel driven refinery and with a hydrocracker a coker is a good alternative but an alternative would be a gasifier with Hydrogen recovery (and Cogen) to run the hydrocracker. The latter solved the hydrogen issue and removes all residual products which the coker have to deal with. It also saves NG, LPG or naphtha from making hydrogen out of.
Stefan Romocki
All conversion processes have the same essential drivers; Revenue (a function of product quality and yield), Operating costs (energy consumed and other expenses such as catalyst), Capital (a function of capacity and complexity) while overall investment return is a product of net revenue over capex.
What we found is that liquid product yield is a major driver for the economics of conversion. Transportation fuels are subject to far less elastic pricing than gases, or heavy products. For example, while oil is $80 today, the price of natural gas (a proxy for refinery fuel gas) is only worth $27 on an energy equivalency basis. That implies within a conversion strategy it is best to minimize conversion to things which become gases and maximize conversion to liquids in the transport fuel boiling range.
If you would like to consider a contemporary conversion strategy, look at high conversion slurry hydrocracking. ENI's EST process is being built commercially at 23,000 bpd in Italy (2012) and offers up to 98% conversion. RIPI's HRH technology is unique in that it operates at mild hydrocracker pressure (70bar) but still offers 90-95% conversion relying on a very active hydrogenation catalyst. Both these processes recover and remanufacture catalyst within the process limits which reduces operating costs and increases run lengths. Most refinery licensing company now offer slurry processes, but our bias is towards the more active catalysts with lower gas and by-product yields.

Attilio Donarelli
My personal opinion on the CONS of each alternative for the Bottom of the Barrel conversion. Still Coker seems to be the most cheap and cheerful solution
Slurry process - not tested commercially
Gasification and Power production - works mainly when the price of electricity is subsidised
SDA - not to couple with Hydrocraker only FCC
Ebullating bed vac residue hydroconversion - work better than in the past but sitll high capex and opex
Coker - what to do with the coke?
Flexicoker - Exxonmobil licensed 4 units to Exxon refineries, 1 in Venezuela and 1 in Greece. Total 6, does it mean anything?
RFCC - not for very high concarbon feeds
Mario Vanacore
at the present crude oil mkt situation (70-80 $/bbl and low margins) coker is certainly one of the most convenient conv technologies, at an higher crude oil price (let say around 100 $/bbl or even higher) other technologies become much interesting (Residue HDC, Ebullated bed, etc). Capex and Opex for all these type of unit are usually higher.
Dr. Amarjit Bakshi
Coming back to the question, if refiner does not have resources to put Delayed Coker which technologies he should consider if any. As I understand that is the question.

Abstract
Mesoporous Aluminosilicates (MAS) showed advantages over zeolites and mesoporous molecular sieves in adsorption desulfurization of diesel fuels. However, the adsorptive capacity still has great space to improve. The equilibrium adsorption data were modeled by Langmuir and Freundlich isotherms. Langmuir model can well describe the adsorption on ion-exchanged MAS. Infer from the hypothesis conditions of Langmuir model, the temperature and the active sites are two key factors to determine the adsorptive capacity. Adsorption experiments were carried out with both model oils and diesel fuels on fixed-bed. The results showed that π-complexation adsorbents were more efficient to remove sulfur compounds at higher temperature and that the saturated adsorption capacity had a linear relationship with the silver ions loaded on the adsorbents.

Abstract
Mesoporous Aluminosilicates (MAS) showed advantages over zeolites and mesoporous molecular sieves in adsorption desulfurization of diesel fuels. However, the adsorptive capacity still has great space to improve. The equilibrium adsorption data were modeled by Langmuir and Freundlich isotherms. Langmuir model can well describe the adsorption on ion-exchanged MAS. Infer from the hypothesis conditions of Langmuir model, the temperature and the active sites are two key factors to determine the adsorptive capacity. Adsorption experiments were carried out with both model oils and diesel fuels on fixed-bed. The results showed that π-complexation adsorbents were more efficient to remove sulfur compounds at higher temperature and that the saturated adsorption capacity had a linear relationship with the silver ions loaded on the adsorbents.

AbstractDesulfurization of heavy straight-run gasoline (HSRG) was accomplished over Ni(II)−Y zeolite. Na−Y zeolite, a nanoporous adsorbent, was synthesized and ion-exchanged with NH4NO3 to obtain NH4−Y zeolite. The obtained material was then converted to H−Y zeolite by calcination. Ni−Y zeolite was prepared by solid-state ion exchange (SSIE) of H−Y zeolite using Ni(NO3)2•6H2O. The breakthrough curve for desulfurization of HSRG containing about 140 ppmw of sulfur compounds was obtained in a batch reactor at ambient conditions. The effects of temperature, Ni content in the zeolite framework, and aging of the zeolite on the desulfurization process were investigated. Ni−Y zeolite exhibited a high capability for the desulfurization of gasoline at ambient conditions.

Abstract
Copper species were incorporated into SBA-15 by solid-state grinding precursor with as-prepared mesoporous silica (SPA). The obtained materials (CuAS) were well-characterized by XRD, TEM, N2 adsorption, H2-TPR, IR, and TG and compared with the material derived from calcined SBA-15 (CuCS). Surprisingly, CuO up to 6.7 mmol•g−1 can be highly dispersed on SBA-15 by use of SPA strategy. Such CuO forms a smooth layer coated on the internal walls of SBA-15, which contributes to the spatial order and results in less-blocked mesopores. However, the aggregation of CuO takes place in CuCS material containing 6.7 mmol•g−1 copper, which generates large CuO particles of 21.4 nm outside the mesopores. We reveal that the high dispersion extent of CuO is ascribed to the abundant silanols, as well as the confined space between template and silica walls provided by as-prepared SBA-15. The SPA strategy allows template removal and precursor conversion in one step, avoids the repeated calcination in conventional modification process, and saves time and energy. We also demonstrate that the CuAS material after autoreduction exhibits much better adsorptive desulfurization capacity than CuCS. Moreover, the adsorption capacity of regenerated adsorbent can be recovered completely.

Abstract
Adsorption and activation of formaldehyde molecule by copper and silver sites in ZSM-5 was studied by combined QM/MM methodology. ETS-NOCV analysis was applied to decompose the deformation density (the difference between electron densities of composed systems and non-interacting fragments) into independent density flow channels. The analysis disclosed that the bonding of formaldehyde by the metal site may be described in terms of lone pair donation from carbonyl oxygen to the metal and π*-backdonation from metal d orbitals to antibonding orbital of CO. The former one is responsible for the formation of coordinate bond (“dative covalent”) and the latter one for the activation of carbonyl bond. Cu(I) site is more efficient with respect to both processes than Ag(I) one. Zeolitic environment is shown to weaken the bond between formaldehyde and M(I) with respect to free cations for both metals whereas it enhances π*-backdonation in the case of copper and diminishes π*-backdonation in the case of silver. Calculated red-shifts of CO frequencies agree well with the IR-measured ones and correlate with the degree of π*-backdonation which rationalizes as well very good performance of Cu(I) site compared to Ag(I) as the role of zeolitic framework in modifying exchanged cation properties.

COSMO-RS based predictions for the desulphurization of diesel oil using ionic liquids: Effect of cation and anion combination
R. Anantharaja and Tamal Banerjee, a,
tamalb@iitg.ernet.in
a Department of Chemical Engineering, Indian Institute of Technology Guwahati, Guwahati, 781039, Assam, India
Abstract
Ionic Liquids ILs provide an important alternative in removing aromatic sulphur compounds by Liquid–Liquid Extraction (LLE). A total of 28 anions and 6 cations resulting in 168 possible combinations were screened via COSMO-RS (COnductor Like Screening MOdel for Real Solvents). Initially benchmarking was performed to predict the infinite dilution activity coefficients of thiophene in ionic liquids. Comparison with literature values involving 8 ILs with 20 points gave the average root mean square deviation (RMS) to be 11%. Thereafter artificial simulated diesel, aromatic sulphur compound and the cation and anion combination was used to predict the capacity (C) and selectivity (S) at infinite dilution. In general the selectivities were found to decrease in the following order: thiophene (4–24) > benzothiophene (2–12)> dibenzothiophene (1–7). The different hetero atom (N,S,O) and its location in the cation structure strongly influenced the selectivity and capacity at infinite dilution for all the three aromatic sulphur compounds. It was found that the cation without the aromatic ring combined with anions having sterical shielding effect such as [SCN], [CH3SO3], [CH3COO], [Cl], and [Br] proved to be the most favourable IL for desulphurization. [EMMOR][SCN] proved to be the most viable IL for the removal of all the three aromatic sulphur compounds.

Abstract: Ionic liquids were found to be highly selective for the extractive removal of aromatic sulfur compounds from fuels at room temperature. The efficiency of ionic liquids for the removal of aromatic sulfur compounds is dependent on the properties and structure of the ionic liquids. In this work, the Lewis-acidic ionic liquid 1-butyl-3-methylimidazolium tetrahalogenoferrate(III) ([BMIM] [FeCl]) was synthesized and demonstrated to be more effective for the removal of aromatic sulfur compounds from diesel over ionic liquids 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM][PF4]) and 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM] [BF46]) because of its Lewis-acidic property. The ionic liquids favorably extracted organic compounds with a higher density of aromatic p-electrons. [BMIM][FeCl] ionic liquid can be regenerated through reextraction by hexane, and could be used in multiple steps for the removal of sulfur compounds from diesel.

Tedium … slogging through (why you need a librarian)
“Housework is a treadmill from futility to oblivion with stop-offs at tedium and counter productivity.” -- Erma Bombeck (U.S. humorist, 1927-1996)
Librarians maintain a low profile. During my career it was not unusual for me to introduce myself as the corporate librarian only to be told, “I didn’t even know we had a library in this company.” As to why we seem to blend into the background is a topic for a future post.
For now I want you to (a) find out if your company supports a library and (b) if it does, to get to know your librarian.
And here is an example of how your friendly information professional can help.
During my periodic scans for desulfurization related items, I ran across a device called HydroSeptor™. An initial search on HydroSeptor™ resulted in several sites associated with inventor Jerry Edmondson. Trouble is, there seems to be precious little about either the inventor or his inventions or his companies that is not produced by Mr. Edmondson himself.
Now imagine that your company is approached by a HydroSeptor™ representative. He persuades you that the HydroSeptor™ is just what your company needs. The representative describes the HydroSeptor™ in the following terms …
“This Patented HydroSeptor(tm) configuration applies heat and FCRS (forced coalescing rapid separation) coalescence to help remove water, salt and other impurities from oil. Mechanical Forced Coalescing enhances the dehydration process and the addition of Adjustable Fluid-Dynamic Flow Control will ensure top performance of the HydroSeptor throughout the life of an oil field”
source: http://www.hydroseptor.com/
Your company is interested, but wants to do due diligence. One part of that due diligence is to search for publicly available information on the inventor, his inventions, and his companies.
Much of the search involves tedious clicking through page after page of Google® and Yahoo!® search results. Googling for “Jerry Edmondson,” for example, results in 28 pages of results. Since there is so little available on “Jerry Edmondson,” it is worth clicking through every page to be sure every little crumb of relevant information is gleaned.
You could do this, but you have (I hope) many other things on your plate. This is where your corporate information professional can help. It is what we get paid to do. We are good at it. And we are glad to do it.
And there’s more. Your librarian probably has access to a number of databases that, due to cost considerations, the company as a whole does not. So he or she can search …
• The D&B database to get a sense of the credit worthiness of Mr. Edmondson’s companies
• The Dialog databases, including Compendex and other technical databases, for a list of articles written by Jerry Edmondson
• The LexisNexis database, for information on lawsuits that Jerry Edmondson may be involved in
Finally, if you are a do-it-yourselfer, your librarian can help you devise search strategies that will maximize your search effectiveness.
And, in case you are interested in Jerry Edmondson’s heavy oil treating devices, here is what I found …

Let your friends & colleagues know about the Desulfurization Blog: http://www.desulf.blogspot.com/
Librarians maintain a low profile. During my career it was not unusual for me to introduce myself as the corporate librarian only to be told, “I didn’t even know we had a library in this company.” As to why we seem to blend into the background is a topic for a future post.
For now I want you to (a) find out if your company supports a library and (b) if it does, to get to know your librarian.
And here is an example of how your friendly information professional can help.
During my periodic scans for desulfurization related items, I ran across a device called HydroSeptor™. An initial search on HydroSeptor™ resulted in several sites associated with inventor Jerry Edmondson. Trouble is, there seems to be precious little about either the inventor or his inventions or his companies that is not produced by Mr. Edmondson himself.
Now imagine that your company is approached by a HydroSeptor™ representative. He persuades you that the HydroSeptor™ is just what your company needs. The representative describes the HydroSeptor™ in the following terms …
“This Patented HydroSeptor(tm) configuration applies heat and FCRS (forced coalescing rapid separation) coalescence to help remove water, salt and other impurities from oil. Mechanical Forced Coalescing enhances the dehydration process and the addition of Adjustable Fluid-Dynamic Flow Control will ensure top performance of the HydroSeptor throughout the life of an oil field”
source: http://www.hydroseptor.com/
Your company is interested, but wants to do due diligence. One part of that due diligence is to search for publicly available information on the inventor, his inventions, and his companies.
Much of the search involves tedious clicking through page after page of Google® and Yahoo!® search results. Googling for “Jerry Edmondson,” for example, results in 28 pages of results. Since there is so little available on “Jerry Edmondson,” it is worth clicking through every page to be sure every little crumb of relevant information is gleaned.
You could do this, but you have (I hope) many other things on your plate. This is where your corporate information professional can help. It is what we get paid to do. We are good at it. And we are glad to do it.
And there’s more. Your librarian probably has access to a number of databases that, due to cost considerations, the company as a whole does not. So he or she can search …
• The D&B database to get a sense of the credit worthiness of Mr. Edmondson’s companies
• The Dialog databases, including Compendex and other technical databases, for a list of articles written by Jerry Edmondson
• The LexisNexis database, for information on lawsuits that Jerry Edmondson may be involved in
Finally, if you are a do-it-yourselfer, your librarian can help you devise search strategies that will maximize your search effectiveness.
And, in case you are interested in Jerry Edmondson’s heavy oil treating devices, here is what I found …

Combine free tools to maximize your effectiveness: Google & LinkedIn
“Words -- so innocent and powerless as they are, as standing in a dictionary, how potent for good and evil they become in the hands of one who knows how to combine them.” -- Nathaniel Hawthorne (American short-story Writer and Novelist, 1804-1864)
As always, this post is about two things … Desulfurization resources (that’s one) … and how to access those resources (that’s two).
Today I’d like you to consider the power of combining membership in a specific LinkedIn group … let’s say, Heavy Oil … with the ability to add an RSS feed to your Google home page.
Both of these tools are free. Both are useful in their own right. But when combined effectively, the two tools multiply their usefulness by an order of magnitude.
Here, as an example, is what happened to me. As a member of the LinkedIn Heavy Oil group, I received the following notice …
