Abstract: A process for the treatment of a light naphtha feedstock that comprises normal paraffins and iso-paraffins may include separating the feedstock into a first iso-paraffin stream and a normal paraffin stream. The separating may be performed with 5A molecular sieves, a pressure of about 1-3 bars, and a temperature of 100-260° C. A product stream may be provided by subjecting the normal paraffin stream to at least one of steam cracking, isomerizing, and aromatizing.

Abstract: Integrated systems are provided for the production of higher hydrocarbon compositions, for example liquid hydrocarbon compositions, from methane using an oxidative coupling of methane system to convert methane to ethylene, followed by conversion of ethylene to selectable higher hydrocarbon products. Integrated systems and processes are provided that process methane through to these higher hydrocarbon products.

Abstract: A process for forming a petroleum product includes introducing a feed stream of a petroleum feedstock to a supercritical water reactor. The feed stream is reacted with supercritical water in the supercritical water reactor, thereby forming a supercritical water reactor effluent. The supercritical water reactor effluent is introduced to a separator to separate the supercritical water reactor effluent into a light stream and a heavy stream. At least a portion of the light stream is introduced to a reformer to concentrate aromatics in the at least a portion of the light stream, thereby forming a reformer effluent. The reformer effluent is mixed with the heavy stream.

Abstract: A process for separating an alkylation product includes introducing a liquid phase alkylation product from an alkylation reaction unit into a first heat-exchanger directly or after being pressurized with a pressure pump and heat-exchanged with a vapor phase stream from the column top of a high-pressure fractionating column, then into a second heat-exchanger and subsequently into the high-pressure fractionating column. The vapor phase stream from the column top of the high-pressure fractionating column is heat-exchanged with the liquid phase alkylation product to be separated, a liquid phase stream from the column bottom of the high-pressure fractionating column is introduced into a low-pressure fractionating column and subjected to fractionation under a condition of 0.2 MPa-1.0 MPa, a low-carbon alkane is obtained from the column top of the low-pressure fractionating column, and a liquid phase stream obtained from the column bottom of the low-pressure fractionating column is an alkylation oil product.

Abstract: A light naphtha feedstock containing olefins is introduced with hydrogen sulfide into a mercaptanization zone for conversion of the olefins into a mercaptan stream that is substantially free of olefins, after which the mercaptans are sent with an alkali caustic solution into a mercaptan oxidation treatment unit (MEROX) to produce a spent caustic stream and sweet light naphtha product stream that is substantially free of olefins and of mercaptans. Disulfide oils are produced from the wet air oxidation of the spent caustic, and the disulfide oils can be further processed to provide high purity olefin building blocks.
