Tianjin Sewage Treatment Plants' biogas recycling project, the double tower loading capacity of the dry desulfurization device is 240 tons, the biogas treatment capacity is 300000m3 per day, and hydrogen sulfide treatment capacity is 1500ppm/m3, less than 20mg/m3 after desulfurization. The desulfurizer filled with this device is a high sulfur capacity ZDE-01 iron oxide desulfurizer produced by our company. It is made of active Fe2O3 as the main component and is added with various additives. It is a new type of highly adaptable and effective dry gas desulfurizer at room temperature that can work under normal temperature and pressure, or pressurized condition. It is of simplicity in equipment, easiness in operation, high sulfur absorption capacity and purification degree, strong adaptability, etc. during use. It can widely be applied to the desulfuration  of natural gas, LNG, gas furnaces, and the removal of H2S in CNG natural gas, coal gas, coke oven gas, shift gas, food carbon dioxide, carbon dioxide regeneration gas, petroleum refining gas, biogas and other gases, there is also a certain removal effect on organic sulfur.

Due to the large loading capacity of the tower, loading efficiency is improved by lifting with the crane
