Concerning Corrosion and Maintenance for CO_2 Stripper in Urea Plant by CO_2 Stripping Method 关于二氧化碳汽提法尿素装置汽提塔的腐蚀与维护
Briefly presents the operation and overhaul of ammonia stripper of urea plant over the years, especially sums up the turnover of the stripper during its overhaul in2004. 简要介绍尿素装置汽提塔历年来运行及检修情况,特别针对2004年汽提塔调头检修的情况作了总结。
By improving startups and shutdowns method and adding a stripper, the process gas condensate and carbonate dioxide condensate from purification section of ammonia plant are properly treated, thus ensuring the environmental protection recovery, recycling usage and energy economizing. 通过改进开停车方法和增加1套汽提塔设备来处理合成氨装置净化工段的工艺冷凝液和二氧化碳冷凝液,确保环保回收,循环使用,达到节能效果。
Analysis of Differential Pressure Fluctuation in CO_2 Stripper for Melamine Plant 三聚氰胺装置C02汽提塔压差波动原因分析
Analyzing of CO_2 Stripper and NH3 Stripper in Urea Plant CO2汽提法与NH3汽提法尿素装置汽提塔的分析比较
CO2 concentration in solvent and the pressure of stripper are the two key factors. The reduction of efficiency of power plant would be decreased if proper concentration and pressure are chosen. CO2在吸收液中的浓度和再生塔压力是最关键的影响因子,研究表明恰当的CO2浓度和再生塔压力将有效地减少电厂效率的降低。
