Pretreatment system can meet biogas engine/turbine gas ratio for high quality of methane(CH4). The system has the customized de-siloxane tank, de-sulphide, dust filters and Chiller.
- Acceptable fuel gas pressure: 10~20 KPa, CH4 content ≥50%
- Gas low heat value (LHV) ≥23MJ/Nm3. If LHV＜23MJ/Nm3, gas engine power output will decrease and electrical efficiency will decrease.
- Gas doesn’t include free condensation water or free materials (the size of impurities
should be less than 5μm.)
- H2S content≤ 100ppm. NH3 content≤ 50ppm. Silicon content ≤ 5 mg/Nm3
- Impurities content≤30mg/Nm3, size≤5μm, Water content≤40g/Nm3, no free water.
