蒸氨工段运行总结

Sum-Up of Operation of Ammonia Still Section

采用蒸氨工艺回收浓氨水(180 tt)制成液氨,实现等压氨回收工段氨水零排放,环境效益显著。实际运行情况表明:蒸氨工段每天可回收液氨超过8 t,年直接经济效益可达180万元以上1,年即可收回投资。

The ammonia still process is used to recover concentrated aqua ammonia（ 180 tt）for the production of liquid ammonia, to realize zero discharge of aqua ammonia from the isobaric ammonia recovery section, so the environmental benefit is remarkable. The actual operation shows that over 8 t of liquid ammonia can be recovered from the ammonia still section a day, the direct economic benefit can reach more than 1.80 million yuan a year, and the investment can be recovered in a year.
