Gas Compression
Cryogenic Compression
Cryogenic compression handles gases at temperatures far below ambient — from near-cryogenic duties in low-temperature gas processing through to the extreme conditions of air separation and industrial gas liquefaction at temperatures approaching absolute zero. It is one of the most technically demanding compression environments, where lubricant behaviour at very low suction temperatures is as important as performance at normal operating conditions.
NEXT Lubricants supports cryogenic compression with compressor lubricants developed for air separation, industrial gas liquefaction, low-temperature process gas and LNG infrastructure applications.

Cryogenic Compression — Process, Applications & Compressor Role
Cryogenic compression involves compressing gases at suction temperatures significantly below ambient — from near-cryogenic duties above -60°C through to conditions approaching cryogenic temperatures in air separation and gas liquefaction processes. At these temperatures, lubricant behaviour changes substantially from ambient operating conditions — viscosity increases, fluidity at cold startup becomes critical, and lubricant pour point must be matched to the minimum temperature the compressor will encounter across its full operating cycle.
The compressor must perform reliably from cold ambient startup through to stable cryogenic suction conditions — a temperature range that places specific demands on lubricant viscosity behaviour across the entire startup-to-operating temperature envelope. In air separation and industrial gas liquefaction, lubricant carry-over into the process stream is unacceptable for both product purity and safety reasons, making oil separation performance and lubricant volatility important design considerations alongside low-temperature fluidity.
Air Separation
Compressors collect and pressurise raw biogas from anaerobic digesters, covered lagoon systems and landfill gas extraction networks, compressing it for onward treatment, energy recovery or combined heat and power generation.
Industrial Gas Liquefaction
Nitrogen, hydrogen, helium and other industrial gases are liquefied for bulk transport and storage in cryogenic vessels. Liquefaction compressors handle gas at sub-ambient and near-cryogenic suction temperatures in continuous duty across the liquefaction cycle.
Low-Temperature Hydrocarbon Gas Processing
Ethylene recovery, NGL fractionation and low-temperature gas processing involve compression of hydrocarbon gas streams at sub-ambient temperatures, where lubricant low-temperature performance must be matched to the specific suction conditions of the process.
