水溶液全循环法尿素装置节能改造技术应用总结

Application Summary of the Energy-Saving Technologies in the Total Urea Plant

针对水溶液全循环法尿素装置消耗偏高的问题,实施尿塔塔盘更新、分解气热能充分回收、水解流程改造、蒸汽分级利用等举措后,实现了装置的节能降耗、增产增效。

To solve the high energy consumption problem in the total urea plant, take the following measures：replace urea tower trays, fully recycle the heat from the decomposition gas, revamp the hydrolysis process, and utilize the grading steam, etc. After revamp, the energy is saved, the consumption is decreased, the yield is increased and also the benefits.
