Abstract: Methods and systems of producing chemical feedstocks from crude oil can include: introducing a fraction of crude oil into a catalytic hydrovisbreaker reactor, wherein the crude oil fraction is dealkylated after introduction; introducing a product stream from the catalytic hydrovisbreaker reactor and a solvent into a solvent de-asphalter unit; and introducing de-asphalted oil from the unit into a two-stage hydrocracker to produce the chemical feedstocks. The crude oil fraction can be atmospheric residue or vacuum residue. The chemical feedstocks can include C3− gases, C4-C5 gases, naphtha, BTX, and gas oil. The chemical feedstocks can be used to produce olefins and polymers.

Abstract: A method for recovering ethylene from cracked gas comprises: (a) hydrogenating a composition comprising acetylene and an acetylene extraction solvent to produce a first gaseous hydrocarbon stream and a first liquid stream; (b) contacting the first gaseous hydrocarbon stream with a second acetylene extraction solvent stream in an acetylene scrubber unit to produce a second liquid stream and a gaseous ethylene product stream; (c) contacting the first liquid stream of step (a) with the second liquid stream of step (b) in an ethylene stripper unit to produce a recovered gaseous ethylene stream and a third liquid stream; and (d) providing the recovered gaseous ethylene stream to step (b).
