Cat Gas Engine Lubricant, Fuel, and Coolant Recommendations Caterpillar

Dry natural gas is a mixture of methane and traces of heavier hydrocarbons. Dry natural gas has been processed in order to remove liquids. This gas has a low tendency to detonate.

For dry natural gas, the acceptable limit of hydrogen sulfide is 0.43 mg/MJ (0.45 µg/Btu).

The heat value of dry natural gases may vary. This depends on the composition of the gas. Dry natural gas usually has an LHV that is between 33.53 to 34.65 kJ/L (900 to 930 Btu/cu ft). Cat Gas Engines are adjusted at the factory with a dry natural gas that is within this range.
