尿素装置CO_2压缩机组控制策略

Control Tactics for CO_2 Compressor of Urea Unit

详细介绍了尿素装置CO2压缩机组的控制策略。一套完善的控制方案能够有效地保护压缩机安全和节能降耗,同时减轻工艺操作人员工作强度。尤其是在多机组串、并联应用时,采用一套完善的、合理的、自控程度高的控制方案时,只要对整个控制目标(主变参数)进行设定,就完全可以达到预期要求。

Details are given of the control tactics for the CO： compressor of the urea unit. A per-fect control plan is able to protect effectively the safety of the compressor and save energy and lowerconsumption, and also reduce the work intensity of the process operators. In particular, with several compressors connected in series or parallel, the adoption of a perfect, rational control plan with a high degree of automatic control will meet the expected requirement completely as long as the whole control objective （principal variable parameter） is set.
