NGL Series

Summit NGL Series synthetic natural gas compressor oils are polyalkylene glycol lubricants formulated to combat problems associated with high pressure reciprocating compressors pumping natural gas, carbon dioxide, or process gases. The lubricant problems generally encountered with the compression of natural gas and CO2 are related to the reaction of the gas stream with 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 rates or use of heavily compounded oils to compensate for hydrocarbon and CO2 dilution and wash-out can damage the well formation and plug CO2 injectors.

- Gases such as CO2 and H2S may be corrosive to compressor components. NGL protects against the corrosive effect of these gases to compressor components while maintaining lubricating properties.

NGL Series lubricants are extremely resistant to hydrocarbon and CO2 dilution and absorption of the gas stream components. 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 or CO2 injectors. The extremely high viscosity index of the NGL Series lubricants allows protection over a broad temperature range. The low pour point provides all-season ease of handling even in very cold climates. The use of pressurized and heated tanks as well as heat traced lines can be eliminated. Summit NGL Series can offer these same advantages when compressing a number of other difficult gases including hydrogen, helium and nitrogen.

ISO 9001

Summit first received its ISO 9001 certification in January of 1996, demonstrating a commitment to quality assurance and performance monitoring. ISO 9001 certification is an international quality standard that addresses a comprehensive list of business elements, including management responsibility, order processing, purchasing, process control, traceability, handling of non-conforming product, and internal auditing. Our present ISO 9001 certification is proof of our continuing quality commitment to our customers.


ISO 14001

Summit is committed to protecting the environment, the health and safety of our employees, customers and communities where we work and live. We recognize that through integrating sound environmental health, and safety management practices into all aspects of our business ... we can offer innovative products and services while conserving and enhancing resources for future generations.


NSF ISO 21469

ISO 21469 specifies hygiene requirements for the formulation, manufacture, use and handling of lubricants, which may come into contact with products during manufacturing or processing. The international standard applies to lubricants intended for use in food production, as well as cosmetic, pharmaceutical and animal feed industries. NSF ISO 21469 Certification by an independent, third party provides Summit with a means to obtain international acceptance for their products.
