摘要
云南沾益化肥厂原设计采用气动仪表进行控制。1987年对尿素生产控制部分进行改造,用TDCS-2000两台基本控制器对尿素生产中与节能及产品质量有关的关键控制点,如NH_3/CO_2比、O_2/CO_2比等进行控制,至1987年7月投运以来,取得了一定的经济效益,受到各方面的欢迎。
Renovation of an urea process control system was worked out with two TDCS-2000 basic controllers. Key control loops, such as NH_3/CO_2 and O_2/CO_2 ratio controls, are deliberately included, which provide plant economy results.
