Liquefaction
Main Cryogenic Heat Exchanger (MCHE)
The principal cryogenic heat exchanger in many liquefaction processes where treated natural gas is cooled, condensed and subcooled using refrigeration streams.
Why it matters
The MCHE is a central integration point among pretreatment quality, refrigerant compression, temperature profiles and LNG production.
