Abstract

The invention relates to the field of liquid-gas separation, especially to the field of flue gas desulphurization, specifically to a compound desulfurizer for flue gas. The objective of the invention is to provide a sulfur dioxide absorbent used for absorption of a membrane contactor. The compound desulfurizer for flue gas is composed of tartrate and an aqueous solution of organic amine mixed according to a mol ratio of 1: 0.5-3. The compound desulfurizer has the advantages of good chemical stability, small foamability, small viscosity and a wide source, easy purchasing and a low price of raw materials. A desulphurization process using the compound desulfurizer has the advantages of a high mass transfer coefficient, no disturbance during flowing of gas and fluid, small mass transfer resistance, a high desulfurization rate, convenience in operation, great operational flexibility, no secondary pollution and stable running in the membrane contactor.

Description

technical field

[0001] The invention relates to the field of liquid-gas separation, in particular to the field of flue gas desulfurization, and more specifically relates to a flue gas composite desulfurizer. Background technique

[0002] SO in the flue gas of coal-fired power plants and metallurgical industries 2 It is one of the main pollutants in the atmosphere and the source of acid rain. With the increasing requirements of environmental protection on the emission of air pollutants, in the flue gas desulfurization purification, how to reasonably select the desulfurization process to achieve SO 2 Emissions in line with the national emission standards is a key issue for the healthy development of flue gas desulfurization in coal-fired power plants and metallurgical industries. Therefore, various high-performance SO 2 The development of absorbents is one of the research topics in this field. In recent years, composite absorbents have become a hot topic in the research and...
