Abstract

Processes and systems for making recycle content hydrocarbons, including olefins, are provided that integrate a cracker unit with one or more other processing units. For example, in some cases, a fluidized catalytic cracking unit may be used to crack recycle content pyrolysis oil and the effluent from the FCC may be further processed in a conventional cracker unit, including its downstream separation zone, to provide recycle content hydrocarbon product stream. In other cases, a pyrolysis unit and cracking unit may be co-located and may share at least one utility, service group, boundary, conduit, energy exchange zone, and/or geographical area.
