What is Propylene Gas?

Propylene or Propene, is an alkene and unsaturated organic compound. Differently from Propane, it has a double bond that gives it a combustion advantage i.e. it burns hotter. The dominant technology for producing propylene is steam cracking. The same technology is applied to ethylene. Propene is the second most important starting product in the petrochemical industry after ethylene. It is the raw material for a wide variety of products.

 

Propylene Uses In Various Industries

Polypropylene manufacturers consume nearly two-thirds of global production. Polypropylene end uses include films, fibers, containers, packaging, and caps and closures. Propene is also used to produce important chemicals such as propylene oxide, acrylonitrile, cumene, butyraldehyde, and acrylic acid. In industry and workshops, propene is used as an alternative fuel to acetylene in Oxy-fuel welding and cutting, brazing, and heating of metal for the purpose of bending.

It has become a standard in BernzOmatic products and others in MAPP substitutes now that true MAPP gas is no longer available.

FAQs about Propylene

How do you separate Propylene?

Separating propylene/propane mixtures is one of the most challenging processes in the petrochemical industry. Propylene can be separated by fractional distillation from hydrocarbon mixtures obtained from cracking and other refining processes. Currently, the most widely used propene separation method by industry is cryogenic distillation.
