1. A system for dimerizing cyclopentadiene (CPD), the system comprising:
a debutanizer comprising:
a feed of C4-C7 hydrocarbons;
a C4 hydrocarbons overhead stream;
a C6+C7 hydrocarbons rich bottoms stream; and
a C5 hydrocarbons rich side draw comprising cyclopentadiene; and
a dimerizer comprising:
a feed from the C5 hydrocarbons rich side draw comprising cyclopentadiene;
a feed from at least a portion of the C6+C7 hydrocarbons rich bottoms stream;
and a pyrolysis gasoline bottoms product stream.
