CO_2汽提法尿素工艺降低蒸汽消耗的根本途径

The Prime Way to Reduce Steam Consumption of CO_2 Stripping Urea Process

CO2汽提法尿素工艺是市场占有率最大的尿素工艺,但经历数十年的发展,蒸汽消耗始终无法大幅度降低。介绍了CO2汽提法尿素工艺的技术特点,在分析了影响蒸汽消耗的各种因素的基础上,提出了增加中压段是CO2汽提法尿素工艺降低蒸汽消耗的根本途径。

CO2 stripping urea process has the maximum market share in the world, but sharp reduction of steam consumption is still not evident even through dozens of years’ development. This paper introduces the technical features of CO2 stripping urea process and addresses that adding medium pressure section is the prime way to reduce steam consumption of CO2 stripping urea process based on analysis of various factors which affect steam consumption.
