Title: CONVERSION OF WASTE PLASTIC TO PROPYLENE AND CUMENE
Abstract:
A process for producing propylene and cumene comprising converting plastics to hydrocarbon liquid and pyrolysis gas in pyrolyzer; feeding hydrocarbon liquid to hydroprocessor to yield hydrocarbon product and first gas stream; introducing hydrocarbon product to second separator to produce first C6 aromatics and refined product; feeding refined product to steam cracker to produce steam cracker product; introducing steam cracker product to third separator to produce second C6 aromatics, third propylene stream, second C2&C4 unsaturated stream, C1-4 saturated gas, and balance hydrocarbons product; introducing pyrolysis gas and/or first gas stream to first separator to produce first propylene stream, first C2&C4 unsaturated stream, and saturated gas stream; feeding first and/or second C2&C4 unsaturated stream to metathesis reactor to produce second propylene stream; feeding first and/or second C6 aromatics, and first, second, and/or third propylene stream to alkylation unit to produce cumene; and conveying balance hydrocarbons product to pyrolyzer and/or hydroprocessor.
