Abstract
Official abstract text for this publication.
A system and a process for dimerizing cyclopentadiene (CPD) including producing a C 6 +C 7 rich bottoms stream and a C 5 rich side draw from a debutanizer, where the C 5 rich side draw and at least a portion of the C 6 +C 7 rich 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.
First claim
Opening claim text (preview).
What is claimed is: 1. A system for dimerizing cyclopentadiene (CPD), the system comprising: a debutanizer comprising: a feed of C 4 -C 7 hydrocarbons; a C 4 hydrocarbons overhead stream; a C 6 +C 7 hydrocarbons rich bottoms stream; and a C 5 hydrocarbons rich side draw comprising cyclopentadiene; and a dimerizer comprising: a feed from the C 5 hydrocarbons rich side draw comprising cyclopentadiene; a feed from at least a portion of the C 6 +C 7 hydrocarbons rich bottoms stream; and a pyrolysis gasoline bottoms product stream. 2. The system of claim 1 , wherein the dimerizer is a thermal dimerizer. 3. The system of claim 1 , wherein a C 6 -C 7 hydrocarbons rich tar solvent makeup stream is drawn from the C 6 +C 7 hydrocarbons rich bottoms stream and a balance of the C 6 +C 7 hydrocarbons rich bottoms stream is directed to the dimerizer. 4. An ethylene plant comprising: A system for dimerizing cyclopentadiene (CPD), the system comprising: a debutanizer comprising: a feed of C 4 -C 7 hydrocarbons; a C 4 hydrocarbons overhead stream; a C 6 +C 7 hydrocarbons rich bottoms stream; and a C 5 hydrocarbons rich side draw comprising cyclopentadiene; and a dimerizer comprising: a feed from the C 5 hydrocarbons rich side draw comprising cyclopentadiene; a feed from at least a portion of the C 6 +C 7 hydrocarbons rich bottoms stream; and a pyrolysis gasoline bottoms product stream. 5. The ethylene plant of claim 4 , wherein the dimerizer is a thermal dimerizer. 6. The ethylene plant of claim 4 , wherein a C 6 -C 7 hydrocarbons rich tar solvent makeup stream is drawn from the C 6 +C 7 hydrocarbons rich bottoms stream and a balance of the C 6 +C 7 hydrocarbons rich bottoms stream is directed to the dimerizer.
