Abstract
PURPOSE: To recover high-purity ammonium sulfate and decrease COD and NH4-H in drained water, by adding Cu (compound) and ammonia water to a coke-oven gas desulfurization waste liquid so that the copper concentration becomes a prescribed value and by causing wet oxidation under a limited condition and concentrating a reaction liquid separated from a gas.
CONSTITUTION: Cu (compound) 4 and NH35 are added to a coke-oven gas desulfurization waste liquid 1 and diluting water 2 in a storage vessel 3 so that the copper concentration of the waste liquid becomes 0.1W50ppm. The pressure of the waste liquid is raised by a boosting pump 6. After a gas 8 containing O2 is compressed at 7 and introduced into the waste liquid, the liquid is conducted to a wet oxidation column 9. Wet oxidation is caused by the O2-containing gas at a temperature of 150°C or more while a portion of water is kept liquid. The waste liquid is separated from a gas at 10. The exhaust gas is washed at 11 and then released at 12. The separated solution is introduced into a crystallization vessel 13 and heated to remove moisture 14. The concentrated liquid is conducted to a separator 15 so that drained water 18 is separated. Ammonium sulfate separated from the liquid is dried at 16 at that high-purity ammonium sulfate 17 is recovered.
