Main components of desulphurization agent for biogas purification:
Ferric oxide (Fe2O3.H2O).
Introduction:
MT-1 type desulfurization agent, whose main compoents is Ferric Oxide, is processed together with a variery of different accelerators. With Features of high sulfur capacity, deep purification, good strength, anti-water and good regeneration. Hydrogen sulfide can be removed even with the absence of oxygen and ammonia. Meanwhile a certain amount of organic sulfur can also be removed.
MT-2 type desulfurization agent is produced under advanced production process based on the MT-1, adding a small amount of high activity components, with characeristics of high desulfurization accuracy, fast reaction rate, a wide range of desulfurization and high sulfur capacity under anaerobic conditions.
MT series of ferric-oxide desulfurizer is mainly used for water gas, semi-water gas, coke oven gas, biogas, natural gas, LNG, oilg and other gases in the fileds of city gas, fertilizer, coking, citric acid, winery, metallurgy, textile, light industry and electronics.
Performance and features:
1, Process conditions:
Temperature: 10-80 ºC;
Airspeed: 500-1500h-1;
Superficial line speed: 0.10-0.30 m / s;
Pressure: atmospheric pressure -8MPa;
Humidity: the higher the humidity the better, preferably close to saturated water vapor, but strictly no water is allowed to flow into the bed; bed height-diameter ratio ≥ 3.
2, No special heating and energy consumption is required, but in winter outdoor applications, desulfurization device must be insulated to avoid gas overcooling, reducing the activity of desulfurization agent and the bed of water and deteriorating operation.
3, The quantities of desulfurization agent required is subect to the following conditions:
-Feed gas H2S concentration and gas flow;
-Sulfur capacity of desulfurization agent;
-Desulfurization tower volume size.
