Product Description:
Hydroxide Iron oxide desulfurizer is a kind of high sulfur capacity desulfurizer produced by using industrial synthesized iron hydroxide as active ingredient, adding special additives and special technology.

Application of hydroxide iron oxide desulfurizer:
It is widely used in the removal of hydrogen sulfide in natural gas, oil field associated gas, biogas, coke oven gas, semi-water gas, water gas and other gases, and also has certain removal effect on mercaptan organic sulfur and most nitrogen oxides.

Performance characteristics:

1. It has high purification, high strength, no mud when meeting water, etc.
2. It has simple equipment, convenient operation, small bed resistance, strong adaptability, fast desulfurization, high sulfur capacity, no secondary pollution, etc. Even under the anaerobic condition, it also has high desulfurization.

Operating conditions:
1. airspeed: 500-1500h^-1 (it can be appropriately increased when the pressure is increased or the hydrogen sulfide content is low)
2. Linear speed: 0.1-0.4m/s (empty tower)
3. Pressure: normal pressure ~6Mpa(or pressurized to within 3.92×10⁶)
4. Temperature: normal temperature ~300ºC

The dosage of desulfurizer is determined by the following conditions:
1. Hydrogen sulfide concentration and gas flow rate in feed gas
2.Requirement value of hydrogen sulfide concentration at the outlet of sulfur tower
3.Desulfurization agent replacement cycle

Application of MT series iron oxide desulfurizer:
MT series iron oxide desulfurizer is mainly used for removing hydrogen sulfide from water gas, semi-water gas, coke oven gas, natural gas, liquefied gas, waste gas, oil field gas and other gases in biogas, city gas, chemical fertilizer, coking, citric acid, winery, metallurgy, prevention and control, light industry, electronics, environmental protection and other industries. This series of products also has the characteristics of simple equipment, convenient operation, strong adaptability and low bed resistance in use.

Main technical indicators:
1. Process conditions:
Temperature: 10-80ºC;
Airspeed: 500-1500h^-1;
Empty tower linear speed: 0.10-0.30m/s
Pressure: normal pressure ~8MPa
Humidity: The higher the humidity, the better, preferably close to saturated water vapor, but it is forbidden to bring water into the bed; The bed height-diameter ratio is ≥3.
2. There is no need for special heating and energy consumption during desulfurization, but the outdoor desulfurization device must be kept warm in winter, so as to prevent the gas from being too cold, reduce the activity of desulfurizer and worsen the operation due to water accumulation in the bed.
3. The required amount of desulfurizer is determined by the following conditions:
    Concentration and gas flow rate of hydrogen sulfide in feed gas;
    Sulfur capacity of desulfurizer
    The volume of the desulfurization tower.
    Desulfurization agent replacement cycle


The significance of desulfurization
Hydrogen sulfide is an inorganic compound. Under normal circumstances, it is a colorless, flammable acid gas. When the concentration is low, it has a foul smell and smells like rotten eggs. When the concentration is high, there is no smell, because high concentration of hydrogen sulfide can paralyze the olfactory nerve. It can be dissolved in water. At 0ºC, 1 mole of water can dissolve about 2.6 moles of hydrogen sulfide. The aqueous solution of hydrogen sulfide is called hydrogen sulfuric acid, which is a weak acid. When it is heated, hydrogen sulfide escapes from the water. Hydrogen sulfide is a kind of acute toxicity, which can be fatal in a short time by inhaling a small amount of high concentration hydrogen sulfide. Low concentration of hydrogen sulfide has effects on eyes, respiratory system and central nervous system.
Hydrogen sulfide is a strong neurotoxin, which has a strong stimulating effect on mucous membrane. Tears, eye pain, intraocular foreign body sensation, photophobia, blurred vision, runny nose, burning sensation in throat, cough, chest tightness, headache, dizziness, fatigue, confusion, etc. appear after short-term inhalation of high-intensity hydrogen sulfide. In severe cases, brain edema and pulmonary edema may occur. When the concentration is extremely high (more than 1000Mg/m3), the patient may suddenly fall into a coma within a few seconds, resulting in lightning death. High concentration contact with conjunctiva causes edema and corneal ulcer. Long-term low concentration exposure can cause neurasthenia syndrome and autonomic dysfunction.
Environmental protection and new energy is the theme of development in the 21^st century. The treatment of air pollution is imminent, among which desulfurization is very important.Biogas, natural gas, coke oven gas, semi-water gas, oil associated gas, gas and wastewater contain toxic gas of hydrogen sulfide, which seriously corrodes equipment and pipelines. Inhalation of a small amount can cripple Days and Nights in Wuhan and seriously endanger life. Sulfur-containing gases must be removed from hydrogen sulfide before they can be used as clean energy.
With the rapid development of economy, desulfurization treatment is the key to solve the problem of environmental pollution. It is a responsibility of our environmental protection industry to improve the desulfurization efficiency in an all-round way. To promote the continuous improvement of environmental quality, create the greatest value for the society and build a beautiful world with sky blue, green space and clear water!
