A Treatment Method For Ammonia Liquor And A Purification Method of COG By Using The Treated Ammonia Liquor

摘要

Nongan to remove the sulfur components of nongan water treatment method and a sulfur component is removed, the present invention relates to a method for purifying coke oven gas using the number nongan, nongan is contained in water of 5-20% excess equivalent of sulfuric acid equivalent weight of hydrogen sulfide in contrast by charging the iron to remove the iron sulfide precipitate is formed hydrogen sulfide nongan of water is removed. Emulsion to the gas-liquid cheopchok nongan the coke oven gas and be less than 25 ℃ the hydrogen removal treatment is to remove the hydrogen sulfide in the coke oven gas with a high efficiency. Hydrogen sulfide is reduced, the amount of generation of SO _X by using a COG removed with high efficiency in the fuel and it is possible to manufacture of environmentally friendly clean fuel.
