carbonation gas

The subject has completed existing tail gas purification and recovery system from four aspects: ( 1) carbonation tail gas purification;

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；

As carbonation tail gas ammonia cleaning and furnace gas washing, the water of ammonia cleaning of filtering machine do not effect the efficiency of ammonia cleaning and the total efficiency of carbonation ammonia cleaning reached to 98.7%;

滤碱机过滤尾气的净氨水，作为碳化尾气净氨和煅烧炉气洗涤，并不影响净氨效率，碳化净氨总效率达到98.7%；

CO_2 sequestration by mineral carbonation, namely greenhouse gas CO_2 reacting with non-carbonate minerals to form geologically stable mineral carbonates, such as CaCO_3, MgCO_3, is a new technology for the reduction of carbon dioxide emissions to the atmosphere.

将温室气体CO2以碳酸盐（如CaCO3、MgCO3）的固体形式永久储存起来，即CO2矿物碳酸化固定，是减少大气中CO2含量，解除温室效应的一种全新方法。
