ABSTRACT
The unit control of solenoid valve, pump and mass flowmeter instead of centralized control in sequential simulated moving bed chromatography(SSMB) for purification of xylitol mother liquor resulted in a low efficiency and other disadvantages. Therefore, a new SSMB separation system was developed based on PLC as controller and SSMB operation process as controlled object, adopting King View to design control screen, in order to achieve the control of industrial production process. Temperature, pressure, flow and mass concentration in separation process were input by measuring the analog connected with PLC and the results were output to an actuator following data processing and corresponding control operations. This paper described the compositions of the system and the realization of related functions including the control function. The creative system was validated by purifying xylitol mother liquor using SSMB and the excellent consequences revealed that the control system of SSMB based on PLC and King View had a positive effect on ensuring safe production and increasing production due to the suitable running temperature and simple operation and may have a realistic significance for improving modernization.
