Requirements for Fuel Gas

In order to ensure its reliable and stable operation of the generator set, the requirements for the natural gas quality is as follows:
--Natural gas should be dehydrated without any water, crude oil & clean oil
--Natural gas pressure 100~400kPa
--Natural gas temperature -20~40ºC
--Total sulfur content less than 200mg/m3
Note: Gas volume is under standard condition with 100kPa atmosphere, 20ºC ambient temperature, 30% relative moisture.

Requirements for Cooling Water

Soften water is required by high temp and low temp engine circulation system. Cooling water should be lightly alkaline clean water without any corrosive compound, such as chloride,sulfate or acid etc. The main index requirements are as follows:
 

Hardness	0.7~5.3me/L
Chloride Ion Content	<150mg/L
PH value	7~8.5

Requirements for Lubricant
