The subject has completed existing tail gas purification and recovery system from four aspects:(1) carbonation tail gas purification;(2) ammonia cleaning of soda ash filtering machine filtered tail gas;(3) NH3 and CO2 recovery and utilization of sodium carbonate producing tank;(4) distillation and recovery of furnace gas condensate.

本课题从四个方面完善现有纯碱尾气净化与回收系统：(1)碳化尾气净化；(2)滤碱机过滤尾气净氨；(3)出碱槽NH_3、CO_2的回收与利用；(4)炉气冷凝液的蒸馏与回收。

The distillated condensate of furnace gas showed that NH3 cleaning efficiency will reach to 98% and the recovery rate of CO2 reach to 30% while adoptingMl asabsorber, CO2 in tail gas recovered for carbonation-soda ash production, then ammonia and CO2 are recovered; the condensation of ammonia in waste water is lower than 0.5tt, CO2 is below 0.03tt, so it can be used directly as soft water, then it has decreased the total quantity of various water containing ammonia in soda ash making system and improved environment.

蒸馏炉气冷凝液表明，以M I作为吸收剂，NH_3的净氨率达到98％，CO_2回收率达到30％，尾气中的CO_2再用于碳化制碱，氨和二氧化碳得到回收利用；废淡液中氨的浓度低于0.5tt，CO_2低于0.03tt，可直接作为软水使用，降低了含氨杂水的总量，使纯碱系统不再多余含氨杂水，改善了环境。
