500kVA/625kVA Shale Gas Generator Set

Shale gas is exploited from shale bed; its main part is located in dark mud shale or high carbon clay shale, it is a kind of natural gas which adsorbs to or dissociates in mud stone, high carbon mudstone, shale and silt shale etc. Its main content is alkane. Among its compositions the majority is methane. Ethane, propane and butane take a little proportion; it also contains Hydrogen sulfide (H2S), carbon Dioxide (CO2), Nitrogen (N2), aqueous vapor and small amount of inert gas, such as Helium (He) and Argon (Ar) etc. Besides, there are many by-products in the process of refining oil from oil shale, the exhaust gas can be used as gas fuel like coal gas.Requirements for shale gas:Within 1m from gas intake valve
Shale gas temperature≤40ºC
Pressure of oil shale gas:3-10kap,rate of pressure change≤1kpa/s;
H2S≤20mg/Nm3;
NH3≤20mg/Nm3;
Tar content≤50mg/Nm3;
Impurity particle size≤5μm, impurity content≤30mg/Nm3;
Moisture content≤40g/Nm3;
Gas heat value≥4.2MJ/ Nm3;If fuel gas contains higher quantity of sulfur and ammonia, it not only corrodes the pole of spark plug seriously, but also increases the acid value of lubricant oil, which corrodes internal parts of genset and corrodes the genset with precipitates.
