Dry Desulfurization
Product Description:
Dry desulfurization system is our company according to the user's gas hydrogen sulfide (H2S) requries the use of periodic and related data made by professional design standardization, the actual content of gas desulfurization process, gas, tailored dimensions and internal structure, different types of gas, hydrogen sulfide content in different gas desulfurization equipment, the size of different gas pressure design the different, different internal structure. The desulfurization system is suitable for the gas with low hydrogen sulfide content, large processing capacity and high desulfurizaation precision, especially for prolonging the service life of the methane utilization equipment.
Dry Desulfurization Project for Biogas Plant:
This dry desulfurization system is a standardized biogas purification process specially designed and manufactured by our company according to the H2S content in biogas, the required service life span and other relevant data. The dimensions and internal structure of desulfurization equipment vary with the type of gas, gas pressure and hydrogen sulfide content. The desulfurization system is particularly suitable for the gas with low hydrogen sulfide content, small processing capacity and high desulfurization precision. What's more, it can effectively prolong the service life of the methane utilization equipment.
Working Principle:
The basic principle of dry desulfurization is a method of oxidizing H2S to elemental sulfur or sulfur oxides by oxygen. The other method is the special iron oxide absorption method (MT series special iron oxide desulfurizer), that is, the active ferric oxide in special iron oxide desulfurizer is used to absorb hydrogen sulfide in the gas and convert it into ferric sulphide, thus removing hydrogen sulfide (at present, this method is mostly used). The composition of the dry process equipment is that a filler is filled in a tank, and the filler layer can be iron oxide desulfurizer, activated carbon desulfurizer, etc. It is better to use iron oxide desulfurizer, so the sulfur content of desulfurizer is large and the cost is low. At a low velocity, the gas passes through the packing layer of the tank from one end, and the hydrogen sulfide is oxidized to sulfur or sulphur oxide or converted to iron sulfide. The gas is left in the packing layer and the gas is discharged from the other end of the container.
Fe2O3 · H2O+3H2S=Fe2S3 · H2O+3H2O
2Fe2S3 · H2O+3O2 = 2Fe2O3 · H2O+6S

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 21st 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!
