Propylene - Bulk

C3H6

The two main sources of propylene are as a byproduct from the steam cracking of liquid feedstocks such as naphtha as well as LPGs, and from off-gases produced in fluid catalytic cracking (FCC) units in refineries.

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.
