Abstract

Co-extraction techniques for separating and purifying butadiene and isoprene from a Chydrocarbon mixture including butadiene and a Chydrocarbon mixture including isoprene are provided. In an exemplary embodiment, a system includes a dimerization heat exchanger, a Cpurification column; an extraction zone including a mainwasher column, a rectifier column and an afterwasher column; a distillation zone; a degassing zone; and an isoprene finishing column. The system can further include a Cwasher column, an absorption column, and a distillation column.
