Description

C5 Pygas processed in the CPD Dimerization Unit is fractionated into DCPD and Isoprene-enriched C5 Cut, that can be sent either to an Extraction Plant for Isoprene Recovery or to a Hydrogenation Plant. The DCPD Process has the flexibility to cope with varying Product targets; for CPD conversions of 85 to 90%, DCPD purity is 83%. In the same Unit, a DCPD of 91-92% is obtained by limiting the CPD conversion to 50-60%. A Unit put on stream in 1991 produces both 83% and 92% purity DCPD depending on the application. After the CPD separation step, the remaining C5 Cut is concentrated in Isoprene and Pentadiene enriched C5 Cut and can be sent to an Extractive Distillation Unit. There, an Isoprene-Pentadiene Stream is removed from the C5 Olefins and Paraffins. Isoprene and Pentadiene can then be separated by Superfractionation.
