尿素深度水解控制方案的改进与实施

Control scheme improvement and implement of urea deep-hydrolysis

分析了尿素深度水解装置中解吸塔温度、压力波动的原因,并从控制方案、仪表选型等方面提出了改进措施及控制回路的实施方法。

This paper analyzes reasons why temperature and pressure fluctuation of desorption tower in urea deep-hydrolysis device, not only proposes improvement measure from control scheme and instrument selection, but also introduces implementation method of control loop.
