摘要
利用水溶液循环法尿素装置产生的尿素残液,替代液氨或氨水作为氨法烟气脱硫系统的脱硫剂,降低尿素装置深度水解系统负荷,使尿素外排废水达标排放的同时,提高氨法烟气脱硫系统的经济性。此技术在尿素生产企业具有较为普遍的推广性。
Using residual liquid produced by urea plant with total aqueous solution recycle process instead of liquid ammonia or ammonia spirit as desulfurizer for flue gas desulfurization can not only lessen the load of deep hydrolysis system in urea plant, make waste water discharged by urea plant meet the GB standard, but also improve economic efficiency of flue gas desulfurization system. This technology can be promoted for urea plants adoption.
