Ethylene (R1150)
C2H4
Ethylene (R1150) is supplied as a compressed liquid in cylinders and ISO tube skids and as a cryogenic liquid in T75 cryogenic isocontainers for international transport. It is generally used in very low temperature industrial refrigeration applications such as LNG liquefaction processes.
