Engineered for cryogenic extremes.

LNG facilities cool gas to -163°C under continuous duty. Our absorbers, exchangers, and ASME vessels are built for exactly that — extreme temperatures, corrosive contaminants, and long service life.

Treatment · Liquefaction · Storage

Supporting the full LNG value chain.

The LNG process begins with pre-treatment of feed gas to remove impurities such as H₂S, CO₂, H₂O, mercury, and higher hydrocarbons, before cooling to cryogenic temperatures between -145°C and -163°C for storage and transport. Harris Thermal partners with LNG producers, EPCs, and OEMs to deliver the ASME-code equipment this demanding chain requires — including Lethal Service and Cyclic Service designs per ASME Section VIII.
