Propane - Bulk

C3H8

Propane is separated from a natural gas stream by absorption in a light oil. It is then stripped along with butanes as liquefied petroleum gas (LPG) and separated by fractional distillation: propane boils at -42° C (-43.6° F).

It is filled into T50 ISO containers for international transport as well as road trailers and rail cars. ISO Containers are approved by UN, RID/ADR, CSC, AAR-600, DOT, TC, TIR, UIC.
