烟气中硫资源回收利用的技术经济分析

摘要

我国是硫资源消耗大国，同时也是硫资源进口大国，而我国每年排放的烟气中所含的大量硫资源并没有得到理想的利用。通过对现有烟气脱硫方法的技术经济分析，提出应大力推进回收烟气中硫资源的技术，推进烟气循环利用和梯度利用，减少烟气排放总量，从而减少污染物的排放量。%China is a big sulfur resource consumption country and a big sulfur resource import country.There are quantities of sulfur resources existing in the flue gas emitted into the air which are not properly utilized.Based on the technical and economic analysis for different flue gas desulfurization methods currently available, it was suggested that recycling technology of sulfur resources in the flue gas should be promoted, so as to realize recovery and cascade utilization of the flue gas, and to reduce the total emission amount of flue gas and the emission of various pollutants.
