摘　　要：对原有NHD脱碳工艺流程进行改进,将低压闪蒸槽移至气提塔上部,取消原流程中的富液泵,空气气提风机由鼓风改为引风,溶液氨冷器由立式改为卧式,减少了投资,节省了操作费用,达到节能改造的目的。The NHD solution decarbonization process is improved by putting the low press evaporator on the top of gas decompress tower, canceling the NHD solution pump, changing positive press air fan to negative press air fan and ammonia solution cooler from upright to horizontal. The result shows that the investment is decreased and the process fee is saved, the purpose of save energy and reduce consumption are achieved.

关 键 词：NHD仍脱碳 改进 节能
