Abstract

A process for the rejection of heavy reaction by-products from a selective hydrogenation reaction zone effluent containing butadiene and trace amounts of heavy reaction by-products by introducing the selective hydrogenation reaction zone effluent into a butadiene extraction vaporizer containing a fractionation zone, refluxing the fractionation zone with a raffinate stream from a butadiene extraction zone; removing a vaporized stream containing butadiene and having a reduced concentration of heavy reaction by-products from the vaporizer; removing and recovering a concentrated liquid product stream containing heavy reaction by-products from the vaporizer; and introducing the vaporized stream containing butadiene into the butadiene extraction zone.
