Gas Compression
Petrochemical Gas Compressor Lubricants
NEXT Lubricants supplies compressor lubricants for petrochemical gas compression across cracked gas, ethylene and propylene compression, recycle gas duties in polymerisation and reactive chemical gas stream applications in petrochemical manufacturing. Product selection is based on gas composition, reactivity, operating pressure and the specific process conditions of the compression duty.

Lubrication Considerations for Petrochemical Gas Compression
Reactive Gas Compatibility
Many petrochemical process gases — including ethylene, propylene, VCM, ethylene oxide and other chemical intermediates — are reactive under certain conditions and may interact with lubricant components at operating temperatures and pressures. Lubricant compatibility with the specific process gas being compressed is a primary selection criterion in reactive petrochemical gas service, where gas-lubricant interaction under operating conditions can affect both lubricant performance and process gas quality.
Condensation of Heavy Components
In cracked gas compressors and recycle gas applications, heavier hydrocarbon fractions can condense within the compressor under certain suction conditions — washing lubricant from cylinder walls and increasing component wear risk. Suction conditions, gas composition across compression stages and the potential for liquid carry-over at the compressor inlet all influence lubricant selection for these applications.
Continuous Duty in Production-Critical Service
Petrochemical compressors operate continuously in facilities where downtime directly halts plant output. Lubricant stability under sustained operating conditions, resistance to deposit formation and extended service life between planned maintenance intervals are important practical requirements alongside gas compatibility — particularly in cracked gas and recycle gas compressors where campaign runs between planned shutdowns can be extended.
