Biogas desulfurization dehydration system model and parameters
Biogas desulfurization dehydration system model and parameters Biogas desulfurization dehydration system use and use method, biogas desulfurization dehydration system detailed introduction, Hongjing environmental protection technology editor Chen manager QQ biogas desulfurization dehydration system process flow chart, biogas as an emerging energy application Widely, it is strictly stipulated in China's environmental protection standards that when using biogas energy, the H2S content in biogas gas should not exceed 20mg/m3. Biogas desulfurization and dehydration systems must remove H2S as much as possible in industrial or civil gases. Biogas desulfurization dehydration system detailed use: Biogas desulfurization dehydration system device working principle: natural gas through the pre-filter dust removal, water removal, in the adsorption tower, using the adsorbent at the low temperature super absorbent characteristics to absorb the moisture in the natural gas, and then The purpose of purifying natural gas is achieved by dust removal through a post filter. When the adsorption tower-tower adsorbent tends to adsorb saturation, it needs to be desorbed (regenerated), at which time it is switched to another tower adsorption; a small amount of purified natural gas is pressurized by a circulation fan, and then heated to enter the regeneration tower, in the regeneration tower. The water is taken out of the tower body by the high-temperature gas, and then separated by cooling and then removed into the adsorption tower to achieve the purpose of regeneration without gas consumption. The biogas desulfurization dehydration system includes: desulfurizer, dehydrator, steam separator, cyclone dehydrator, dry desulfurizer, water sealer and other biogas desulfurization dehydration systems belong to the supporting equipment of biogas project. The biogas directly produced by the anaerobic fermentation tank fermentation cannot be directly burned. The biogas desulfurization treatment makes the biogas a clean and environmentally friendly energy source. For the replacement of hydrogen sulfide and water molecules in biogas, the desulfurization efficiency can reach 99%. After the pre-filter removes dust and removes water, the biogas adsorbs the moisture in the biogas by using the super absorbent property at the low temperature in the adsorption tower, and then removes the dust through the post filter to purify the biogas. When the adsorption tower-tower adsorbent tends to adsorb saturation, it needs to be desorbed (regenerated), at this time, it is switched to another tower adsorption; a small amount of purified biogas is pressurized by a circulation fan, and then heated to enter the regeneration tower, and the regeneration tower is inside. The water is taken out of the tower body by the high-temperature gas, and then separated by cooling and then removed into the adsorption tower to achieve the purpose of regeneration without gas consumption. When biogas is produced from an anaerobic fermentation unit, it carries a large amount of H2S, especially at medium or high temperature fermentation. Biogas desulfurization and dehydration system Because of the large amount of water vapor in the biogas, water and H2S in the biogas work together to accelerate corrosion and blockage of metal pipes, valves and flow meters. In addition, the SO2 produced after H2S combustion combines with the water vapor in the combustion products to form sulfurous acid, which causes corrosion on the metal surface of the equipment, and also causes pollution to the atmospheric environment and affects human health. Therefore, before using biogas, you must use the biogas desulfurization dehydration system to remove the H2S.
