Title: AN INTEGRATED PROCESS CONFIGURATION INVOLVING THE STEPS OF PYROLYSIS, HYDROCRACKING, HYDRODEALKYLATION AND STEAM CRACKING
Abstract:
A process for processing plastic waste comprising converting plastic waste to hydrocarbon liquid and a first C1-4 gas; contacting hydrocarbon liquid with a first hydroprocessing catalyst in hydroprocessing unit to yield a second C1-4 gas and a first hydrocarbon product comprising C5+ liquid hydrocarbons; introducing the first hydrocarbon product to a first separating unit to produce treated hydrocarbon stream comprising C5-8 hydrocarbons and a first heavies stream comprising C9+ hydrocarbons; contacting the first heavies stream with a second hydroprocessing catalyst in hydrodealkylating unit to yield a second hydrocarbon product comprising C5+ liquid hydrocarbons and a third C1-4 gas; conveying the second hydrocarbon product to the first separating unit; feeding treated hydrocarbon stream to steam cracker to produce steam cracker product; separating steam cracker product into olefin gas, saturated hydrocarbons gas, aromatics, and a second heavies stream; and conveying the second heavies stream to hydroprocessing unit.
