Abstract
Systems and methods for producing dicyclopentadiene via thermal dimerization of cyclopentadiene. The feed stream comprising cyclopentadiene is flowed through four shell and tube heat exchangers in series. Each of the shell and tube heat exchangers comprise a shell and one or more tubes disposed in the shell. The feed stream is flowed in the tubes while the heat transfer medium is flowed in the shell to absorb the exothermic heat released by the dimerization of cyclopentadiene in the tubes. In this way, the temperature in the tubes is controlled at a level where the conversion rate of cyclopentadiene is above 99% and the occurrence of runaway reaction is substantially prevented.
