Gas Compression
LNG Infrastructure Compressor Lubricants
NEXT Lubricants supplies compressor lubricants for biogas and biomethane compression across anaerobic digestion plants, landfill gas facilities, biogas upgrading installations and Bio-CNG production. Product selection is based on gas composition, H₂S concentration and the specific operating conditions of the installation.

Lubrication Considerations for LNG Infrastructure
Cryogenic & Sub-Ambient Operating Conditions
Compressors in LNG liquefaction refrigerant circuits and boil-off gas handling operate under sub-ambient or near-cryogenic suction conditions. Lubricant behaviour at low inlet temperatures — including viscosity, fluidity and film formation at cold startup — is a primary consideration alongside performance at normal operating conditions.
Gas Purity & Lubricant Carry-Over
Natural gas and refrigerant streams in LNG facilities are processed to high purity specifications. Lubricant carry-over into the process gas or refrigerant stream is undesirable for both process and equipment protection reasons, making oil separation performance and lubricant volatility relevant design considerations in LNG compressor applications.
Continuous Duty & Reliability Requirements
LNG liquefaction trains and terminal compressors operate continuously in facilities where unplanned downtime carries major operational and commercial consequences. Lubricant stability under sustained operating conditions and extended service life between planned maintenance intervals are important practical requirements alongside technical compatibility.
