Acid Gas Removal Hydrogen Sulfide
Hydrogen sulfide in the removal of acid gas
Today, there is a matter of removing hydrogen sulfide in acid gas, which is an important matter in the chemical industry. Hydrogen sulfide is smelly and highly toxic, and it is harmful to both production and the environment, so it is urgent to remove it.
To remove hydrogen sulfide, there are various methods. One is the chemical absorption method, which selects a suitable absorbent, such as an alcohol amine solution. When hydrogen sulfide encounters this agent, it chemically reacts and remains in the liquid to purify the gas. This alcohol amine is combined with hydrogen sulfide to form a stable compound that can be resolved under specific conditions, so that the absorbent can be recycled and reused, which not only saves cost, but also efficiently removes sulfur.
The second is the physical absorption method, which uses certain solvents to dissolve hydrogen sulfide. At high pressure and low temperature, the solvent absorbs hydrogen sulfide; at low pressure and high temperature, hydrogen sulfide escapes and the solvent has to be regenerated. This is a change in physical properties to achieve the purpose of removing hydrogen sulfide, and the energy consumption is relatively low, which is suitable for specific working conditions.
There is another oxidation method, so that hydrogen sulfide is oxidized and converted into harmless sulfur or sulfate. Or the biological method, depending on the metabolic activities of microorganisms, converts hydrogen sulfide into elemental sulfur and other products. The biological method is mild and environmentally friendly, and has gradually become more and more important in the industry.
However, the method of removing hydrogen sulfide also needs to pay attention to many matters. Such as the material of the equipment, it must be resistant to hydrogen sulfide corrosion to prevent the danger of leakage. During operation, temperature, pressure, flow and other parameters must be precisely controlled to ensure the effect of sulfur removal. And the generated products should be properly disposed of to avoid secondary pollution.
In short, in addition to hydrogen sulfide in acid gas, appropriate methods should be selected and operating norms should be adhered to, so as to ensure production safety, environmental friendliness, and achieve the best of chemical production.
