Linear programs (LPs) are used for crude selection to calculate the optimal crude schedule for a given time frame, generally a month. The pipeline pumping schedule from a crude terminal to the refinery is generated by a simulation scheduling calculation.http://www.hydrocarbonprocessing.com/Article/3558696/A-new-solution-to-the-challenges-of-crude-selection-and-scheduling.htmlWed, 01 Jun 2016 00:00:00 GMTCatalyst replacement strategy for a hydrocracking unit at a Middle East refineryhttp://www.hydrocarbonprocessing.com/Article/3558623/Catalyst-replacement-strategy-for-a-hydrocracking-unit-at-a-Middle-East-refinery.htmlWed, 01 Jun 2016 00:00:00 GMTOptimize isomerization reactor temperatures and component RONhttp://www.hydrocarbonprocessing.com/Article/3558558/Optimize-isomerization-reactor-temperatures-and-component-RON.htmlWed, 01 Jun 2016 00:00:00 GMTSecure the best benefits from C<sub>4</sub> hydrocarbon processing—Part 1: Separation sequenceshttp://www.hydrocarbonprocessing.com/Article/3558709/Secure-the-best-benefits-from-C4-hydrocarbon-processingPart-1-Separation-sequences.htmlWed, 01 Jun 2016 00:00:00 GMTSyngas from H<sub>2</sub>S and CO<sub>2</sub>: An alternative, pioneering synthesis route?Hydrogen sulfide (H<sub>2</sub>S) and carbon dioxide (CO<sub>2</sub>) represent major concerns for the hydrocarbon industry. Both species are contaminants and, since their use as feedstock is minor, are considered troubling byproducts. H<sub>2</sub>S, which mainly derives from oil and gas desulfurization, cannot be vented. Consequently, neutralization is mandatory. Practically every refinery is equipped with a Claus sulfur recovery unit (SRU). Flue gases rich in CO<sub>2</sub> are vented, contributing to climate change; sequestration of CO<sub>2</sub> is technically viable, but remote disposal still remains a questionable end.http://www.hydrocarbonprocessing.com/Article/3558601/Syngas-from-H2S-and-CO2-An-alternative-pioneering-synthesis-route.htmlWed, 01 Jun 2016 00:00:00 GMTUtilize an optimizer to blend gasoline directly to shipshttp://www.hydrocarbonprocessing.com/Article/3558609/Utilize-an-optimizer-to-blend-gasoline-directly-to-ships.htmlWed, 01 Jun 2016 00:00:00 GMTApply a short-term, high-temperature carbon steel solution to piping systemshttp://www.hydrocarbonprocessing.com/Article/3550642/Apply-a-short-term-high-temperature-carbon-steel-solution-to-piping-systems.htmlSun, 01 May 2016 00:00:00 GMTCatalytic coprocessing of used cooking oil with straight-run gasoil in a hydrotreating pilot planthttp://www.hydrocarbonprocessing.com/Article/3551011/Catalytic-coprocessing-of-used-cooking-oil-with-straight-run-gasoil-in-a-hydrotreating-pilot-plant.htmlSun, 01 May 2016 00:00:00 GMTSmall-scale coal-to-chemicals can revitalize India’s petrochemicals industry, economy—Part 2http://www.hydrocarbonprocessing.com/Article/3551002/Small-scale-coal-to-chemicals-can-revitalize-Indias-petrochemicals-industry-economyPart-2.htmlSun, 01 May 2016 00:00:00 GMTUse computational fluid dynamic analysis to revamp fired heatershttp://www.hydrocarbonprocessing.com/Article/3551026/Use-computational-fluid-dynamic-analysis-to-revamp-fired-heaters.htmlSun, 01 May 2016 00:00:00 GMT
