1.  Use and performance 
Biogas  desulfurization  equipment  is  mainly  to  remove  H2S  and  impurities in biogas.  Fill desulfurizer in desulfurization equipment to remove H2S. In purifying performance and operation, 
the desulfurization equipment is with reasonable structure, small bed resistance, high sulfurremoval, easy operation, high sulfur capacity penetration, strong adaptability of  installation site, no secondary pollution, simple and quick installation etc. 
Desulfurizer in the desulfurization equipment, the components are mainly Ferric Oxide, and add 
other efficient purifying material from the processing of additional accelerator. Even in no oxygen 
and no ammonia environment, it also can remove H2S precisely. It also has effect on removal of 
thiols organic sulfur and most of the nitrogen oxides. 


Main reaction principle of desulfurization: 
(1) Fe2O3.H2O+3H2S=Fe2S3.H2O+3H2O  
(2) Fe2O3.H2O+3H2S=2FeS+S+4H2O  
When desulfurizer  is alkaline,  reaction  is according  to  formula 

 (1)  to  right; when desulfurizer  is acid, reaction is according to formula 

 (2) . If H2S gas content  in the outlet gas of  the desulfurization equipment  is more  than the equired value, desulfurizer should be replaced to ensure normal use of desulfurizer and enabling normal 
operation of the desulfurization equipment. 

Desulfurizer usage amount is determined by the following conditions:
A, H2S concentration in the feed gas and the gas flow 
B, Desulfurization tower outlet H2S concentration required value 
C, Desulfurizer Replacement cycle 
2.  Regeneration Operating conditions 
When H2S gas  in desulfurization  tower outlet gas  is more  than 1ppm or exceeds  requirements 
indicators,  and  saturated  sulfur  capacity  is  less  than  30%,  desulfurizer  regeneration  should  be Carried out. 
Operating conditions are: 
Airspeed :0.5-140H-1 (adjustment according to the temperature change of regeneration) 
Pressure: Atmospheric pressure
