乙醇胺法工艺特点与流程Process characteristics and flow of ethanolamine method缺点defect：（）

A、溶液易起泡，影响正常操作Solution easy to bubble, affecting the normal operation；
B、单位体积吸收过多酸气后易于腐蚀设备Too much acid gas per unit volume can corrode equipment easily；
C、不能脱除有机硫，当天然气中含羟基硫时将增大乙醇胺消耗量Organic sulfur cannot be removed and the consumption of ethanolamine increases when natural gas contains hydroxyl sulfur；
D、水、电、汽耗量大，硫磺回收需另增设一套装置Water, electricity, steam consumption is large, sulfur recovery needs another set of equipment
