Requirments for natural gas
1.Methane should be at least 85%
2.The natural gas temperature should be between 0-60 ºC
3. No inpurity should be in the gas. Water in the gas should be less than 20g/Nm3.
4. Heat value should be at least 8500kcal/m3, if less than this value, the power of the engine will be declined.
5. Gas pressure should be 8-14KPa, if the pressure is less than 3KPa, booster fan is necessary.
6.The gas should be dehydrated and desulfurated. Make sure that there is no liquid in the gas. H2S<200mg/Nm3
