Abstract
PURPOSE: To remove hydrogen chloride of any concentration without producing waste water by a method wherein waste gas is subjected to a specific treatment with an aqueous alkaline solution, then an electric dust precipitator is used to remove alkali chlorides from the waste gas.
CONSTITUTION: Hot waste gas 1 containing hydrogen chloride is guided in the spray tower 2, and an aqueous alkaline solution 3 is sprayed from th top of the tower 2. After removing the specified amount of hydrogen chloride in the spray tower 2, the waste gas is guided to the wet-wall tower 5 and brought into contact with an aqueous alkaline solution 7 so that the gas is treated until the concentration of hydrogen chloride in the waste gas reaches the specified value. Next, the waste gas is introduced into the electric dust precipitator 6 so as to remove alkali chlorides and dust contained in the gas, and dust-free gas is discharged to the air. Preferably, the alkaline solution used in the wet-wall tower is adjusted in its concentration and used for spraying in the spray tower.
