H2S and other waste gas purification

Natural gas, as a high-quality, efficient and clean energy source, is increasingly valued by people. But it contains acidic gases such as H2S and other waste gases. Sulfur is a foul-smelling gas with the smell of rotten eggs. It is highly toxic to the human body, flammable and explosive. It is easy to corrode metals and block pipelines. This will lead to threats to personal safety and environmental pollution, so desulfurization must be carried out to meet national standards.

Activated carbon is widely used as an adsorption desulfurizer. It has the advantages of low cost, simple operation and high desulfurization efficiency. The adsorption capacity of different activated carbons was studied. Zhulin desulfurization activated carbon has a very high H2S removal capacity. And this activated carbon is impregnated.

Garbage incineration deodorization

At present, domestic garbage incineration flue gas emission standards are becoming more and more stringent, and higher requirements are put forward for garbage incineration flue gas treatment technology. Therefore, finding an efficient flue gas treatment process is the key to solving the problem.

Huahuang adopts a dry treatment process to spray fine coal-based activated carbon powder through a spray system to produce solid compounds, which are then collected by a dust collector together with fly ash. Zhulin coal-based activated powder generally uses 200 mesh. It is stabilized and collected by the ash collection system. The basic combination process of dry method and bag dust collector is one of the typical flue gas purification processes in garbage incineration plants.

Solvent recovery

For solvent recovery, activated carbon is the preferred and commonly used adsorbent because of its strong adsorption capacity, acid and alkali resistance, heat resistance, rich raw materials, and easy regeneration. At present, the bamboo forest activated carbon used in this field is activated carbon granules, and the common ones are 3 mm and 4 mm particles.

Huahuang solvent recovery activated carbon is made of natural high-quality coal and physical activation method. It is black granular, non-toxic, odorless, porous and developed. It has a strong adsorption capacity for organic solvent vapors within most concentration ranges and is widely used in the recovery of organic solvents such as benzene, xylene, ether, ethanol, acetone, gasoline, chloroform, tetrachloromethane, etc.
