Sequence of installation for dry desulfurization – biogas desulfurization tower: Dehydrator (gas-water separator) → Biogas desulfurization tank → Flame arrester (at the dehydrator) → Cooking appliance. http://5b0988e595225.cdn.sohucs.com/images/20180918/18f5bc9000d743b387ccdf476f5b1f4f.png I. Process flow: Biogas → Dehydration → Desulfurization → Flame arrester → Power generation or boiler combustion. II. Technical parameters of the high-efficiency desulfurization tower: 1. Desulfurization efficiency: ≥98% 2. Desulfurizing agent: Iron oxide and its compounds. III. Main structures inside the tower and the desulfurization process: The dimensions and internal structure are designed specifically based on the actual volume of gas supplied by the user as well as the hydrogen sulfide content in that gas. Desulfurization equipment designed for different types of gases, with varying hydrogen sulfide contents in those gases and different gas pressures, varies in size and internal structure. To monitor in real time the reaction rate of sulfides and polysulfides with oxygen in the air during the regeneration process, temperature monitoring equipment has been added to prevent accidental fires caused by excessive amounts of air being introduced during regeneration, which leads to intense exothermic reactions and temperatures exceeding the ignition point of the desulfurizing agent. IV. Equipment and materials required: desulfurization tower, dehydration tower, flame arrester, pipes, valves. V. Costs incurred during operation: iron oxide desulfurizing agent. VI. For operation, the dry desulfurization tower and the wet biogas desulfurization tower were specifically designed by our factory for the removal of hydrogen sulfide from sulfur-containing gases. It carries out systematic purification of sulfur-containing gases based on practical needs, so that the purified gases can be used for power generation or boiler combustion in compliance with environmental protection requirements. Dry method for removing hydrogen sulfide has advantages such as high efficiency and simplicity, easy management, low cost of desulfurization equipment, long service life, and reliable operation. Suitable for gases with low hydrogen sulfide content, low gas treatment volume, and high requirements for desulfurization accuracy.
