摘要
讨论CO_2气提法和NH_3自气提法尿素生产工艺中气提塔的作用。由此产生的气提效应决定了工艺操作条件、装置的设置,以及所引起的蒸汽、电的消耗问题。
This article mainly discusses the function of the stripper in urea production with CO2(tripping process and NH2 stripping process respectively, from which the stripping effects gained decide the operation conditions, plant settings as well as the related steam and power consumptions.
