Popis: The C5 fraction, which accounts for 15–25% in naphtha, consists of molecules such as isoprene (IP), pentadiene (PD), cyclopentene (CP), and cyclopentadiene (CPD). The C5 fraction can be used to manufacture petroleum resin and other high-value-added products. Yet it is often burned as fuel and not fully utilized because separation of these products with close boiling points is difficult. One common process is to react CPD with itself to form high boiling dicyclopentadiene (DCPD) that can then be separated from other C5 molecules. In addition, extractive distillation is also used to recover alkynes from light ends. Such a process involves the use of multiple separation columns and reaction zones. Furthermore, the reactor is highly coupled with one of the separation columns by two recycle streams, which may lead to a snowball effect and difficulty in controlling the process. Hence, many opportunities for process integration and intensification are available. We describe how the entire process with reaction a...
