A method for recovering paraxylene from a mixture of aromatic hydrocarbons. The process uses a pressure swing adsorption zone followed by a paraxylene recovery zone. The invention provides for lower throughput through the paraxylene recovery zone, resulting in lower capital costs and operating costs.

A remote hydrocarbon processing system comprising a gas compressor skid, gas processing skid, electric power generation skid, liquid storage tank, blending skid, and crude oil source, are fluid flow interconnected and located proximate to a producing well. Produced gases are delivered from the well to the gas compressor skid. Compressed natural gas is delivered to the gas processing skid where it is thermally separated to generate a processed gas stream and a processed liquid stream. The processed gas stream is delivered to the electric power generation skid and burned to generate electricity that may be delivered to an electric power transmission line. The processed liquid stream is delivered to the liquid storage tank. Crude oil from the crude oil source and processed liquid stream from the liquid storage tank are delivered to the Blending skid and blended into a lower viscosity, higher API gravity transportable crude oil.
