水溶液全循环法尿素装置先后进行了真空预浓缩工艺改造和中低压循环系统优化改造,改造后水溶液尿素装置蒸汽消耗由1410kg/tur下降到1000kg/tur以下,取得了全循环法尿素蒸汽消耗的突破。
A full-cycle aqueous urea plant has been vacuum vacuum preconcentration process and the transformation of low-pressure circulation system optimization and transformation of the aqueous urea solution after the steam consumption dropped from 1410kg / tur below 1000kg / tur achieved full circulation urea breakthrough in urea consumption breakthrough .
