Ethylene - Bulk
C2H4
Ethylene is produced by the steam cracking of ethane. It is filled into T75 cryogenic isocontainers as a liquid or tube skids as a compressed liquid for international transport. Skids are approved by DOT, TC, RID / ADR and IMO. Cryogenic containers are approved by UN, RID/ADR, CSC, AAR-600, DOT, TC, TIR, UIC.
