摘要
SCR脱硝技术中还原剂氨的来源主要有液氨、氨水和尿素,另有少量使用碳酸氢铵的技术方案。碳酸氢铵和尿素一样,是农业化肥,具有安全无毒的特点。通过对碳酸氢铵和尿素制氨法所使用原料的物理化学性质、制氨技术工艺、系统安全性、稳定性等作出分析,比较每种方案的技术优缺点;对制氨原料价格进行市场调查,进行经济分析。最后,对主要技术经济指标进行数据对比,得出结论。
Ammonia used as reducer for SCR technology, generally there are three methods to produce ammonia： liquid ammonia,aqueous ammonia and urea, in addition, ammonium bicarbonate method is also used in a few technology schemes. The same as urea, ammonium bicarbonate is also a fertilizer for agriculture, which is safety and non-toxic. It was analysied physical and chemical propoties, process, safety, stability of ammonium bicarbonate and urea, it was also compared the advantages and disadvantages of each scheme;An inventigation on raw-material prices, and a technical analysis were done. The technical and economic datas were compared,then giving conclusions in the end.
