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
