What’s New with Vacuum Resid Hydrocracking

Experience is the name every one gives to their mistakes.” -- Oscar Wilde (Irish Poet, Novelist, Dramatist and Critic, 1854-1900)

My 2009 post about ChevronTexaco’s Vacuum Resid Slurry Hydrocracking (VRSH) has been so popular that I decided to search for more current news on the process.  One of the items appearing in search results was …

LC
MAX and Other LCFINING Process Enhancements to Extend Conversion and Onstream Factor
AFPM Annual Meeting, March 11-13, 2012, Manchester Grand Hyatt, San Diego, CA
AM-12-73
Presented By:
Mario Baldassari and Ujjal Mukherjee
Chevron Lummus Global
Abstract
Recent process enhancements incorporated into our LC-FINING unit designs and operating experience gained from recently commissioned units have led to a new generation of plants with reduced investment, improved energy efficiency, enhanced conversion capabilities and improved unit on-stream factors. An example of such a unit is GS Caltex’s 60 kBPSD Vacuum Residue Hydrocracker, which was commissioned the 3rd quarter of 2010 just 42 months after the kick-off of the Basic Engineering Design. This unit was able to achieve design throughput and conversion within 40 days of introducing vacuum residue feed and has been able to realize an on-stream factor of 94 percent over its first 18 months of operation, exceeding industry norms by 4 percent. In addition to the extended conversion capabilities of our LC-FINING process, Chevron Lummus Global has proceeded to develop the LC-MAX process to further alleviate conversion constraints. LC-MAX combines LCFINING and solvent deasphalting in an integrated hydroprocessing configuration, enabling residue conversions of 85 volume percent to be attained, even when processing very difficult high sediment forming opportunity crudes.

Call for Papers: Energy Efficiency

“If you call a tail a leg, how many legs has a dog? Five? No, calling a tail a leg don't make it a leg.” -- Abraham Lincoln (American 16th US President (1861-65), who brought about the emancipation of the slaves. 1809-1865)

Devising desulfurization methods that do not require huge amounts of energy remains a major challenge to the refining industry.  Consequently, you may want to attend or even contribute to an upcoming energy efficiency conference.

Global Technology Forum (http://www.gtforum.com/) has issued a call for papers for its Energy Efficiency conference, scheduled for 18 April 2013 in Brussels.

Here are a few details abstracted from an email notification I received.

///////

The neck bone connected to the head bone

“Life is hardly more than a fraction of a second. Such a little time to prepare oneself for eternity!” -- Paul Gauguin (French painter, printmaker, and sculptor, 1848-1903)

Everything is connected to everything else.  Take the following article, for example …

///////
In-situ Electrochemical Desulfurization of Crude Oil and Its Fraction,” by Dr. Ahmad D. Hammad, Dr. Zaki Yusuf and Nayef Al-Rasheedi, IN: Saudi Aramco Journal Of Technology Summer 2012
"The advantages of in-situ hydrodesulfurization is that it is carried out in milder conditions, at lower temperature (~250 °C) and pressure (~40 atm) with lower hydrogen partial pressure. The process also has the ability to accommodate various types of low cost electrocatalysts for targeting the poly-aromatic molecules during the electrocatalytic reactions, thereby reducing the total cost."
source: http://www.saudiaramco.com/content/dam/Publications/Journal%20of%20Technology/Summer%202012/JOTSummer2012_electrochemical_desulfurization.pdf
///////

As interesting as the article is, Dr. Hammad’s bio is even more thought provoking.  He
"is currently leading the Solar Energy sub-team under the Carbon Management Team in the Research and Development Center (R&DC)"

I Googled® using the following search string …

Aramco solar

The results were remarkable.  Saudi Aramco, it seems, is into solar in a BIG way.  Here is a sample of what I found.

Saudi Aramco has set up a venture capital arm called Saudi Aramco Energy Ventures (http://www.aramcoventures.com/) whose purpose is to identify and invest in emerging technologies that are a strategic fit with the oil giant.  Solar energy is at the top of the list of areas of interest.

In addition, Saudi Aramco has built several pilot solar energy plants, including the following …

“The King Abdullah Petroleum Studies and Research Center, (http://www.kapsarc.org) built by Saudi Aramco, will include solar panels that will generate 3.5 megawatts of energy.

“A new Saudi Aramco-built solar facility at the King Abdullah University of Science and Technology (
http://www.kaust.edu.sa/) will generate two megawatts of energy.

It would appear that the oil bone is connected to the sun bone.

China and India: Two Countries, Two Conferences

“A building has integrity just like a man. And just as seldom.” -- Ayn Rand (Russian born American Writer and Novelist, 1905-1982)

The economies of China and India are growing fast.  Their energy needs are growing as well, with all the attendant problems thereof, including desulfurization.  Consequently, much research on the problem is being published in these two countries.
 
For example, the Google® Scholar search string desulfurization AND (china OR india) results in a couple of interesting articles.

Advance in Adsorptive Desulfurization
ZHOU Wei, XU Wan-zhen*, HUANG Wei-hong, LI Hui, WU Xiang-yang (School of Environment,Jiangsu University, Zhenjiang 212013, China)
Compared with traditional hydrodesulfurization, adsorptive desulfurization which has mild conditions, significantly efficient and financially feasible is becoming a popular research in the trend of oil deep desulfurization. The adsorptive desulfurization method, mechanism, absorbents and absorbents regeneration were reviewed. According to adsorption mechanism, a series of adsorbents such as zeolite,activated carbon,metal oxide and composite metal oxide, clay, and research of their absorbability were introduced. Some suggestions to further research of adsorptive desulfurization were also proposed.

Abstract
Chromium promoted sulfated zirconia (CSZ), prepared by wetness impregnation technique, was characterized by various techniques like Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Scanning electron microscopy (SEM) and Electron probe microscopic analysis (EPMA). Bulk density and Brauner–Emmett–Teller (BET) surface area of CSZ were found to be 0.996 kg/m3 and 116.2 m2/g, respectively. CSZ was further used as catalyst for the oxidative removal of sulfur from model oil (dibenzothiophene, DBT, dissolved in iso-octane). Optimum CSZ dose was found to be 5 g/l. The catalytic oxidation of DBT by CSZ was found to be gradual process with optimum reaction time of 6 h. The activation energy for DBT conversion by CSZ was found to be 3.8 kJ/mol.

Abstract
The membrane process concept coupled with phase inversion technique has been successfully applied for the first time for the preparation of ionic liquid (IL) encapsulated microspheres using polyetheretherketone with card group (PEEKWC), trihexyl(tetradecyl)phosphonium chloride[CYPHOS IL 101] in N,Ndimethylformamide (DMF) as dispersing phase and dodecane, ethanol and water as continuous phases. The technique yields porous, spongy, spheres with smooth surface and diameter around 1000 lm, with morphology and chemical composition strongly affected by preparative conditions. IL loading capacity and subsequent surface topography has been investigated using optical microscopy, FT-IR, SEM, EDX, TGA and SDT.

Abstract
A series [C3Omim][X] of imidazolium cation-based ILs, with ether functional group on the alkyl side-chain were synthesized and structure of the materials were confirmed by various techniques like 1H, 13C NMR spectroscopy, MS-ESI, FTIR spectroscopy and EA. More specifically, the influence of changing the anion with same cation is carried out. The absorption capacity of CO2 for ILs were evaluated at 30 and 50 ºC at ambient pressure (0-1.6 bar). Ether functionalized ILs shows significantly high absorption capacity for CO2. In general, the CO2 absorption capacity of ILs increased with a rise in pressure and decreased when temperature was raised. The obtained results showed that absorption capacity reached about 0.9 mol CO2 per mol of IL at 30 ºC. The most probable mechanism of interaction of CO2 with ILs were investigated using FTIR spectroscopy, 13C NMR spectroscopy and result shows that the absorption of CO2 in ether functionalized ILs is a chemical process. The CO2 absorption results and detailed study indicates the predominance of 1:1 mechanism, where the CO2 reacts with one IL to form a carbamic acid. The CO2 absorption capacity of ILs for different anions follows the trend: BF4 < DCA < PF6 < TfO < Tf2N. Moreover, the as-synthesized ILs is selective, thermally stable, long life operational and can be recycled at a temperature of 70 ºC or under vacuum and can be used repeatedly.
