Gas Compression
Cryogenic Compressor Lubricants
NEXT Lubricants supplies compressor lubricants for cryogenic and near-cryogenic compression applications across air separation, industrial gas liquefaction, LNG infrastructure and low-temperature process gas duties. Product selection is based on suction temperature, gas handled and the lubrication requirements of the specific compressor design.
Knowledge
Lubrication Considerations for Cryogenic Compression
Low-Temperature Fluidity
Lubricants in cryogenic and near-cryogenic service must remain fluid and functional at the minimum suction temperatures encountered in the system — from near-cryogenic duties above -60°C through to sub-ambient conditions approaching cryogenic temperatures. Lubricant pour point and low-temperature viscosity are primary selection criteria for compressors operating in this temperature range.
Gas Purity & Contamination Risk
In air separation and industrial gas liquefaction, any lubricant carry-over into the cryogenic process stream is unacceptable — both for product purity reasons and for the safety implications of lubricant contamination in liquid oxygen and other cryogenic products. Oil separation performance and lubricant volatility are important design considerations in oil-lubricated cryogenic compressor systems.
Wide Operating Temperature Range
Cryogenic compressors must start reliably from cold ambient conditions and reach stable operating performance across a wide temperature range before reaching steady-state cryogenic suction conditions. Lubricant viscosity behaviour across the full startup-to-operating temperature range influences compressor startup reliability and the time required to reach stable operation.
