Abstract
According to one embodiment of the present disclosure, a method of processing a hydrocarbon feed includes fractionating the hydrocarbon feed into a light stream and a heavy stream; hydrotreating the heavy stream to form a hydrotreated heavy stream; feeding the light stream and the hydrotreated heavy stream to a single Fluid Catalytic Cracking (FCC) reaction zone, thereby producing a product stream which includes light olefins. The light stream may be exposed to more severe FCC cracking conditions than the heavy stream, within the same FCC reaction zone. The single FCC reaction zone may be operated in a down-flow configuration and the FCC may be operated under high severity conditions. The light stream may include hydrocarbons boiling at less than 371° C. and the heavy stream may include hydrocarbons boiling at greater than 371° C.
