Abstract
Systems and processes for producing one or more olefins are provided. A feed containing Ccompounds can be dehydrogenated to provide a first product containing butene. At least a portion of the first product can be bypassed around a methyl-tert-butyl-ether production unit and cracked in a first cracker to provide a second product containing propylene, ethylene, and butane. A light hydrocarbon containing gas oils, full range gas oils, resid or any combination thereof can be cracked in a second cracker to provide a cracked hydrocarbon containing propylene, ethylene, and butane. An alkane can be cracked in a third cracker to provide cracked alkanes containing propylene, ethylene, and butane. The second product, cracked hydrocarbons, and cracked alkanes can be combined and separated to provide a third product containing propylene and a first recycle containing butane. At least a portion of the first recycle can be recycled to the first product prior to cracking. At least a portion of the first recycle can be recycled to feed prior to dehydrogenation.
