Why Change TO Propylene

 

Propylene Source

Propylene is obtained during the refining of gasoline, and to a lesser extent by the splitting, cracking and reforming of hydrocarbon mixtures.  Propylene is a by-product of oil refining and natural gas processing. It may also be taken from naphtha cracking.  Propylene is separated by fractional distillation from hydrocarbon fractions. For higher product qualities, further distillation is required.  The shale gas industry opened up an alternative production path by dehydrogenating propane to yield Propylene.

 

Propylene Uses and Applications

Propylene is used in organic synthesis to produce, e.g. the following materials:

  • acetone
  • isopropanolacrylonitrile
  • propylene oxide

 

Propylene in major quantities is polymerised to form polypropylene plastics.

 

It is used as a refrigerant in high/medium/low temperature applications including commercial refrigeration and airconditioning. It has the ASHRAE number R-1270.

 

Propylene is used in mixtures for the calibration of process control instruments in the petrochemical/chemical industry.

 

Propylene is widely used as a chemical intermediate.

 

Propylene is used in emission calibration mixtures for the automotive industry.

 

Propylene is used in the efficiency testing of gas burners and engines.

 

Propylene is used as a component in calibration gases for the chemical industry.
