Methods may comprise: (a) causing pyrolysis of a plastic feedstock to produce a first stream of C1-C4 gaseous hydrocarbons and light gas olefins and a second stream comprising the remaining pyrolysis components. The second stream and hydrogen gas may be fed into a hydrocracker to produce a third stream of gaseous C1-C4 hydrocarbon gases and a fourth stream comprising the remaining hydrocracker components. The fourth stream may be fed to either (i) a steam cracker to produce a fifth stream comprising C1-C4 gaseous hydrocarbons and light gas olefins, a sixth stream comprising C6-C8 hydrocarbons and a seventh stream comprising hydrocarbons heavier than C8; or (ii) a fluidized catalytic cracker to produce an eighth stream comprising C1-C4 gases and light gas olefins and a ninth stream comprising hydrocarbons that are C5 or greater.

Abstract: Systems and methods for recovering phenol have been disclosed. The methods of recovering phenol includes concurrently processing, in a phenol recovery unit, a crude phenol stream from a phenol production unit, and a bisphenol-A purge stream from a bisphenol-A production unit to produce a first product stream comprising 60 to 95 wt. % phenol. The phenol recovery unit comprises a crude phenol distillation column and a bisphenol-A-phenol distillation column. The processing includes distilling a bottom stream from the crude phenol distillation column in the bisphenol-A-phenol distillation column.
