Liquefied natural gas (LNG) plays a critical role in the global energy supply chain, enabling efficient transport and storage of natural gas. The process begins with pre-treatment of feed gas to remove impurities such as H₂S, CO₂, H₂O, mercury, and higher hydrocarbons. Feed gas is then cooled to cryogenic temperatures between -145°C and -163°C, condensed, and stored in specialized double-wall insulated tanks for transport.
LNG facilities require robust, high-spec equipment engineered to withstand extreme temperatures, corrosive contaminants, and continuous duty cycles. Harris Thermal partners with LNG producers, EPCs, and OEMs to deliver ASME-code process equipment designed for safety, reliability, and long service life.
Our Equipment for LNG Processing
Gas Treatment and Pre-Conditioning
- Absorber Towers & Columns – For CO₂, H₂S, and contaminant removal prior to liquefaction.
- Scrubber Vessels – For particulates, acid gases, and mercury control.
- Separator Vessels & Knock-Out Drums – For gas-liquid separation before cryogenic cooling.
Liquefaction and Cryogenic Systems
- Shell & Tube Heat Exchangers – For pre-cooling, sub-cooling, and refrigerant cycle integration.
- Condensers & Chillers – Applied in cascade and mixed-refrigerant systems.
- Evaporators – For auxiliary services such as LNG regasification, boil-off gas management, or solvent recovery.
Storage and Handling
- ASME-Certified Pressure Vessels – For refrigerants, solvents, and intermediate process fluids.
- Cryogenic Storage Tanks – Double-wall insulated vessels designed for safe storage and transport.
- Mixing & Utility Vessels – Supporting refrigerant blending, antifreeze systems, and utility fluids.
Ancillary and Balance-of-Plant Equipment
- Crystallizers – For salt or by-product recovery in LNG water treatment systems.
- Cyclones & Separators – For gas/liquid/solid separation in pre-treatment and boil-off gas handling.
