Abstract

A system and a process for dimerizing cyclopentadiene (CPD) including producing a C+Crich bottoms stream and a Crich side draw from a debutanizer, where the Crich side draw and at least a portion of the C+Crich bottoms stream are directed to a dimerizer where the CPD is thermally dimerized to dicyclopentadiene (DCPD). DCPD is more stable than CPD and thus safer to handle.
