Why produce propylene from propane ?

Propane dehydrogenation (PDH) is a process step in the production of propylene from propane. PDH is vital to the petrochemical industry : propylene is the second most important starting product in the petrochemical industry after ethylene. Propylene is the raw material for plastic polypropylene, which is a common component mainly used in the automotive and textile industries, for plastic films for packaging and many other products

In 2008, the worldwide sales of propylene reached a value of over 90 billion US dollars.

Which equipment for this application ?

Mainly used in cryogenic distillation processes, BAHX cool down streams to very low temperatures in the range of -100°C or lower. The BAHX offer high performance in terms of heat transfer with compactness. They are also used as condensers and re-boilers for distillation columns.
