output of 60,000 tons of synthetic ammonia Desulfurization Process design is specified by the teacher determine the scale of production output, with production internship in the collection of various production technologies designed to target. This design is used by the desulfurization extract, its main raw materials and semiwater gas desulfurization liquid. The detailed design of the Section on the production of ammonia desulfurization principle, process, technology parameters, the heat balance, the material balance and the selection of equipment, plant layout and waste treatment. The design of the desulfurization efficiency and renewable rate of a breakthrough. [Keyword]: tannin extract to take off a sulphur method take off a sulphur liquid take off sulphur tower
