WIPO Patent Application WO/2022/095148
Kind Code:
A1
Abstract:
Provided is a method for applying a membrane separation apparatus (24) to ammonia desulfurization, comprising an ammonia desulfurization apparatus and a membrane separation apparatus (24). The ammonia desulfurization apparatus comprises an absorption tower (1), the absorption tower (1) using circulation fluid desulfurization, and a water washing circulation fluid (10) washes the desulfurized flue gas. The circulation fluid of the ammonia desulfurization apparatus is fed into the membrane separation apparatus (24) for treatment, and the composition, temperature, and pH of the circulating absorption solution in each section of the ammonia desulfurization apparatus are controlled; after treatment, the concentrated solution is returned to the ammonia desulfurization apparatus, and the clear liquor from the membrane separation apparatus (24) is sent to a process water (15) system or to a water washing cycle (10).
