Latest Patents

Yokogawa holds a patent for a process for the recovery of cyclopentadienes. This process allows for the extraction of highly pure cyclopentadiene and methylcyclopentadiene from a cracked gasoline fraction. The merit of this process lies in its ability to integrate a simple distillation system into a conventional cracked gasoline treating plant without requiring alterations to the existing plant or operating conditions. The method involves withdrawing an internal reflux stream from the stripping section of a BTX column and directing it to a depolymerization-distillation column. The overhead stream from this column is then processed in a cyclopentadiene column, followed by a methylcyclopentadiene column, allowing for the efficient recovery of both compounds.
