    Abstract: Sulfur emissions from liquid sulfur are reduced, or even entirely avoided by degassing the liquid sulfur at pressure in an out-of-pit vessel and by sweeping the rundown pit (or vessel) with a sweep gas that is non-poisonous for a hydrogenation catalyst. Acid gases from degassing are fed at pressure to the Claus unit, while sweep gases are fed to the tail gas treatment unit to substantially recycle the acid gases to extinction. In preferred plants and methods, motive fluids and booster eductors or compressors are not needed, and incineration of the acid gases can be avoided.

    Abstract translation: 液体硫的硫排放量减少甚至完全避免,甚至通过在井外容器的压力下对液态硫进行脱气,以及用无氢化催化剂的吹扫气体清扫破碎坑(或容器) 。 来自脱气的酸性气体在压力下进料到克劳斯单元,同时吹扫气体被供给到尾气处理单元以基本上将酸性气体再循环到灭火。 在优选的设备和方法中,不需要运动流体和增压喷射器或压缩机,并且可以避免酸性气体的焚烧。
