Product Description


Membrane Separation Biogas Upgrading Decarburization Purification System to Natural Gas

After two-stage desulphurization processes, then go through our GasDec system (Membrane Separation) for carbon removal, biogas could be upgraded to make CNG, for vehicle or going into national pipeline network.

The gas quality after upgrading as below:
Item Quality Index Comments
High thermal value MJ/m3 >31.4 In the specific geographical area for vehicle driving, under the highest operation pressure, the water dew point shouldn't be higher than -13 degree.C; When lowest ambient temperature lower than -8 degree.C, the water dew point should be 5 degree.C lower than the lowest temperature.
CO2 % ≤3.0
Total Sulfur mg/Nm3 ≤200
H2S mg/Nm3 ≤15
O2 % ≤0.5
Comments: The above data is subject to clients' actual requirements.

Procedures of our biogas upgrading system:

 
1, Primary Filter
The saturated water and partial particles in the raw digester gas are removed through the primary filter;

2, Boosting, Primary desulphurization
The biogas from primary filter is boosted by blower. Then after cooling, the biogas is fed to wet type desulphurization system for primary removal of Hydrogen Sulfide, to make H2S content lower than 200 mg/Nm3;
 
3, Fine desulphurization
The content of Hydrogen Sulfide is made lower than 50 mg/Nm3 through dry type desulphurization system;
 
4, Impurities Removal, Fine Cleaning System
The new dust and impurities in biogas could be removed through the Separator; Then delivered to Fine cleaning system for removals of water and tiny particles in order to protect membrane and guarantee its life-time;

5.  First MS (Membrane Separation)
The high quality compressed biogas goes into the first MS system through gas-distributing pipeline. The exhaust gas could be gathered or discharged into atmosphere;

6.  Secondary MS (Membrane Separation)
The gas out of First-MS goes into Secondary MS system for final decarburization. The exhaust gas would totally return to the inlet of biogas compressor. Thiophane is added into the cleaned gas, after CNG compressor, through dispenser, to be delivered to gas station by tank lorry;
