摘要
针对氨汽提法尿素生产过程中中压吸收塔液位难以控制的问题,介绍了中压吸收塔工作原理;从氨碳比稳定、温度调节、投料量、排放量、阀门控制等方面阐述了控制中压吸收塔液位的方法;提出了中压吸收塔液位过高或过低时的判断方式和处理措施。
In allusion to the problem being difficult to control the liquid level of the middle pressure absorber in the urea production process with ammonia stripping method,the author has introduced the working principle of the middle pressure absorber;described the method controlling the liquid level of the middle pressure absorber from aspects of stabilizing the ammonia/carbon ratio,temperature adjusting,raw material quantity put,discharging quantity,valve control etc.;presented the diagnosis type for the liquid l...
