Dry Natural Gas
Dry natural gas is a mixture of Methane, Ethane and not more than 5 percent Propane and a fractional percentage of Butane. It can also be referred to as commercial pipe line natural gas.The reference to "dry" refers to the absence of liquid petroleum products such as liuid Butane or liquid Propane.The BTU content of dry natural gas can vary. Caterpillar gas engines are factory adjusted with a dry natural gas having a low heat value (LHV) of 905 BTU/feet3 (33.72kJ/I).NGO
Oil recommendation is determined by the gas and the intake air conditions.Units operating on processed natural gas should use oils formulated with additive systems containing between zero and 0.5% maximum slufated ash and meet the CB (Supp 1) clasification. The oils are composed of ashless dispersants and either organo-metallic (provided they do not contain barium, calcium or magnesium) or completely ashless oxidation inhibitors. Your oil supplier knows which oils meet these requirements.Sour gas generally refers to fuels containing sulfur compounds, primarily hydrogen sulfide. (Gases containing no sulfur compounds are referred to as "sweet gas".) Severe damage to engines can occur if this contaminant is ignored. Water vapor and sulfur oxides formed during combustion can combine to form sulfuric acid compounds. Internal components, particularly valve guides, piston rings, and cylinder liners will be subjected to corrosive wear shortening engine service life.If analysis of the fuel shows the concentration of hydrogen sulfide to be greater than 0.1% by volume, the fuel should be treated (scrubbed) to lower the H2S level below 0.1%. When using fuels with 0.1% H2S or less, the following preventive steps should be taken: 1. The coolant outlet temperature should be maintained between 88°C and 93°C (190°F and 200°F).
