Summit NGL 888 Series Gas Compressor Lubricant


Summit NGL-888 polyalkylene glycol lubricant was formulated to combat these problems associated with high pressure reciprocating compressors pumping natural gas, carbon dioxide, or process gases.  NGL-888 is extremely resistant to hydrocarbon dilution and absorption by the gas stream.  Any lubricant carryover will not impair the well formation as it is compatible with well-bore treatment fluids and soluble in water.  The result is a lubricant maintaining the proper viscosity for wear protection, resisting wash-out and carryover, and posing no threat of damage to the well formation.

The extremely high viscosity index of NGL-888 allows lubricant protection over a broad temperature range.  The low pour point provides all season ease of handling even in very cold climates.

Summit NGL-888 can offer these same advantages when compressing a number of other difficult gases including hydrogen, helium and nitrogen.


The lubricant problems generally encountered with the compression of natural gas are related to the reaction of the gas stream to the lubricant.  These include:

  • Solubility of gas in the lubricant causes reduced lubricant viscosity resulting in cylinder scoring and high wear rates.  Compensating for this with a higher viscosity lubricant can cause handling problems at lower temperatures.
  • Absorption of lubricant into the gas stream results in high lubricant usage rates and a depletion of protective lubricant film in the cylinder.
  • Condensed hydrocarbon liquids in the cylinder area can "wash" the lubricant from the cylinder walls causing severe mechanical damage.
  • The carryover from increased lubricant feed rate or use of heavily compounded oils to compensate for hydrocarbon dilution and wash-out can damage the well formation.
