Document Type and Number:
WIPO Patent Application WO/2019/196247
Kind Code:
A1
Abstract:
A method and a device for oxidizing an absorption solution for ammonia desulfurization in an oxidation column (1), wherein the absorption solution is sent to an oxidation column (1) from an absorption column (6) for ammonia desulfurization, and an oxidized solution is sent to the absorption column (6) for ammonia desulfurization from the oxidation column (1), thus realizing a multistage circulation of the absorption solution; and during the oxidation in the oxidation column (1), a pressurized air is used as the oxidation air, and a multistage air distribution is used, for a compulsory oxidation of the absorption solution, so as to decrease the investment and operation costs and control the production of aerosol during ammonia desulfurization.
