Abstract: Systems and methods for processing full range naphtha and producing light olefins and BTX are disclosed. Full range naphtha is separated in naphtha splitter to produce a light naphtha stream and a heavy naphtha stream. The heavy naphtha stream is then fed to a heavy naphtha catalytic cracker to produce a cracked stream. The effluent from the steam cracking unit and the effluent from the catalytic cracking unit may be flowed into an oil quench tower and are further separated in a separation unit to produce purified ethylene, propylene, butadiene, 1-butene, and BTX. The cracked stream maybe further processed. The light naphtha stream or both the lights stream combined with the light naphtha stream is fed to a steam cracker to produce an effluent stream comprising olefins. Effluent of the steam cracker is fed to the processing unit to separate light olefins. The C6+ hydrocarbons from the processes may be recycled.

Abstract: Systems and methods for processing crude oil and producing light olefins and BTX are disclosed. Crude oil is distilled in an atmospheric distillation column to produce a gas stream, a light naphtha stream, a heavy naphtha stream, a fuel oil stream and a refinery feed stream. Heavy naphtha stream is then fed to a heavy naphtha catalytic cracker to produce a cracked stream. The cracked stream is further processed to produce a lights stream, a heavies stream, and a stream comprising olefins and BTX. The lights stream is combined with the light naphtha stream and fed to a steam cracker to produce additional light olefins. Heavies stream is recycled back to the heavy naphtha catalytic cracker.

Abstract: A method of converting naphtha is disclosed. The method includes heating the naphtha in stages in different heating units. The naphtha is vaporized in the first heating unit. And the vaporized naphtha undergoes the largest temperature change of the process in the second heating unit. A third heating unit can be a part of the reactor. The reactor includes a catalyst which is contacted with the pre-heated naphtha to convert it to C2 to C4 olefins.
