Application of advanced process control technology in refining unit of cyclohexanone
During the production process of the crude alcohol ketone refining unit in the cyclohexanone unit,there are problems such as fluctuations in the amount of feed,feed components and steam pressure.These problems affect the smoothness of the overall operation of the plant,as well as the quality and yield of the final product.In order to solve these problems,according to the process characteristics and process control requirements of the cyclohexanone plant,the project adopts the APC-Suite advanced control software system on the basis of DCS conventional control,combined with the real-time operation data of 100 kt/a cyclohexanone plant,use multi-variable model prediction,combined with advanced control technologies such as expert intelligent control,the optimal control of the whole process of the crude alcohol and ketone refining unit is realized.After the advanced control system is put into use,compared with conventional control,the standard deviation(fluctuation range)of key process parameters is significantly reduced,the operation frequency of operators change from 155 times per day to 10 times per day,and steam consumption is reduced by more than 2.4%.
