探讨硫磺回收装置SO_2排放达标的途径

Discussion on Ways of Reaching Standard of SO_2 Emission in Sulfur Recovery Unit.

摘要: 装置尾气含硫化合物的量决定了烟气中ＳＯ２的排放量，加上烟气流量就决定了烟气中ＳＯ２排放浓度。装置尾气总硫可分为酸性硫、有机硫、元素硫，它们是烟气中ＳＯ２排放达标的三个制约因素，其中每个因素都可能造成烟气中ＳＯ２排放超标。要保证烟气中ＳＯ２排放达标，必须处理好每个制约因素。利用三个制约因素可从新的角度去认识一个工艺或一套装置。

Abstract: SO 2 emission quantity in emission gas is depended on tail gas total sulfur content in sulfur recovery unit. SO 2 concentration can be determined if SO 2 emission quantity and the flow rate of tail gas are considered at the same time. Tail gas total su
