Coke Oven Gas Purification and Refinery Plant


Coke oven gas contains tar, naphthalene, benzene, inorganic sulfur, organic sulfur and other impurities. In order to make full use of coke oven gas, purify coke oven gas, reduce impurity content in coke oven gas, fuel emission can meet the requirements of environmental protection, and can be used as chemical production. The technology is mature and widely used in power plant and coal chemical industry.


Moreover, the byproducts and residues generated during the purification process can also be valuable resources.  For instance, the sulfur compounds can be converted into elemental sulfur, which has various industrial applications.  The tar and benzene can be utilized as raw materials for the production of chemicals, fuels, or other value-added products.

In summary, the Coke Oven Gas Purification and Refinery Plant is an essential facility that ensures the efficient utilization and environmental sustainability of coke oven gas.  Through a rigorous purification process, the plant removes impurities from the gas, allowing it to be used as a clean and reliable source of energy.  Furthermore, the byproducts generated during the process have the potential for further utilization, making the plant a valuable component of the steel industry’s sustainability efforts.
