Gas Compression
Biogas 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.
Knowledge
Lubrication Considerations for Biogas Compression
Biogas composition varies significantly depending on feedstock and treatment stage, creating lubrication conditions that differ from clean natural gas compression and require specific consideration during lubricant selection.
Hydrogen Sulphide (H₂S) Content
Raw biogas typically contains H₂S at varying concentrations depending on feedstock and digestion process. H₂S is corrosive to certain metals and reactive with some lubricant chemistries — H₂S concentration in the gas stream is a primary factor in lubricant selection for biogas compression.
Moisture and Contaminants
Biogas from anaerobic digestion is saturated with moisture and may contain siloxanes, ammonia traces and other contaminants depending on the feedstock. These components can affect lubricant condition over time and influence the appropriate service interval for the installation.
Variable Gas Composition
Biogas composition varies across feedstock types, digester conditions and seasonal changes — affecting the methane/CO₂ ratio and contaminant levels at the compressor inlet. Lubricant selection should account for the range of gas conditions the compressor will encounter across its operating life.
