Abstract: Methods of and systems for producing an olefin are disclosed. A paraffin is dehydrogenated to produce a mixture comprising the olefin and unreacted paraffin. The mixture is then fed to an extractive distillation unit that uses soybean oil as a solvent to extract at least some n-butane from the mixture.

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).
