摘要: Systems and integrated methods are disclosed for processing aromatic complex bottoms into high value products. The system includes an adsorption column, the adsorption column in fluid communication with an aromatics complex and operable to receive and remove polyaromatics from an aromatic bottoms stream. The adsorption column producing a cleaned aromatic bottoms stream with reduced polyaromatic content and a reject stream including the removed polyaromatics. In some embodiments, the reject stream is recycled for further processing, passed to a coke production unit to produce high quality coke, or both.

摘要: The present disclosure relates to a process for the hydrodealkylation of aromatic rich hydrocarbon streams to produce benzene, toluene and mixed xylenes (BTX), with high selectivity towards high value xylenes. The process uses catalysts containing a framework-substituted zirconium and/or titanium and/or hafnium-modified ultra-stable Y (USY) type zeolite.

摘要: An integrated refinery process for removing mercaptans from a hydrocarbon stream containing mercaptans and converting by-product disulfide oil to useful products. The process includes introducing the hydrocarbon stream containing mercaptans into an extraction vessel containing an alkaline solution and passing the hydrocarbon stream through an extraction section of the extraction vessel which includes one or more liquid-liquid contacting decks for reaction to convert the mercaptans to alkali metal alkanethiolates. Further, the process includes withdrawing a hydrocarbon product stream free of mercaptans from the extraction vessel and recovering spent caustic containing alkali metal alkanethiolates from the extraction vessel. Additionally, the process includes subjecting the spent caustic containing alkali metal alkanethiolates to air oxidation to produce a by-product stream containing disulfide oils (DSO) and sulfides and processing the by-product stream in a steam cracking unit to produce a DSO free product stream.

摘要: Refinery processes, systems, and compositions for making an aromatic blending component for fuel oil, and a fuel oil blend using the same. Valuable hydrocarbons like kerosene can be reduced or eliminated from fuel oil blends by adding certain aromatic blending components derived from the aromatic bottoms stream of an aromatic recovery complex. The aromatic blending component can be used in lieu of more costly hydrocarbon streams to decrease the overall viscosity of the fuel oil blend without adding sulfur.

摘要: Oxidized disulfide oil (ODSO) compounds, derived from by-product disulfide oil (DSO) compounds from the MEROX process, are effective as lubricity additives for transportation fuels. Significant increases in lubricity of ultra-low sulfur fuels as measured by the WSD test were observed with addition of ODSO compounds in the range of from 0.1 ppmw to 10 ppmw. This use of ODSO compounds as lubricity additives converts an otherwise DSO waste oil product into a valuable commodity that has utility in improving lubricity properties of transportation fuels.
