Ethane - Bulk
C2H6
Ethane is separated from natural gas by cooling it to very low temperatures by cryogenic turbo-expansion (–73°C to 101°C) and refrigerated absorption at –34°C (–29°F). 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.
