POWER GENERATION GAS ENGINES

Lubricants designed specifically for use with gas engine applications, where acid control, high oxidation stability and extended engine life are important.

Our liquid engineers understand the importance of keeping engines productive and avoiding unscheduled maintenance. We have designed lubricants to handle the high oxidation and nitration stresses of gaseous fuel, and help extend oil-drain intervals and engine life.

Internal combustion engines running on coal gas, biogas, landfill gas or natural gas typically output between 50–20000 kW and each gas type presents its own challenges. We have developed products to support longer engine life in natural gas and mine gas applications, where there are high levels of methane as well as corrosive elements such as hydrogen sulfide.

We have also specifically designed products to help you efficiently neutralize the acids and damaging deposits that impurities in biogas – landfill gas and sewage gas produced from household and industrial waste – can generate on combustion.

Natural gas

• Mainly composed of 80-98% methane, impurities and corrosive elements such as hydrogen sulfide can also be present

Mine gas

• Coal mine methane and abandoned mine methane can be used effectively to generate power and heat with gas engines

Landfill gas

• Gas recovered from anaerobic degradation of organic compounds in household and industrial waste
• Engine oils designed for landfill have to control strong acids and deposits to a much greater extent than required for ‘clean gas’ service

Biogas

• Gas generated by bacterial decomposition of organic materials in solid waste such as sludge, agricultural, food and vegetation waste (digestion tower)
• Engine oils need to control acid build up

To meet the challenges of gas engine operations, our Liquid Engineers recommend the following products:
