Abstract

Systems and methods for producing light olefins and BTX (benzene, toluene, and xylene). Crude oil is first separated to produce light naphtha and heavy naphtha. Light naphtha is fed to a steam cracking unit and heavy naphtha is fed to a catalytic cracking unit. The effluent from the steam cracking unit and the effluent from the catalytic cracking unit are flowed into an oil quench tower and are further separated in a separation unit to produce an ethylene stream, a propylene stream, and a BTX stream. The Chydrocarbons, ethane, and propane from the effluent of the steam cracking unit and the effluent from the catalytic cracking unit are recycled to the steam cracking unit. The non-BTX C+ hydrocarbons from the effluent of the steam cracking unit and the effluent from the catalytic cracking unit are recycled to the catalytic cracking unit.
