Design of Multifunction Equipment for Middle-experiment Chromatographic Separation and Its Control System
Ling Xu · Journal of Zhengzhou University of Technology · 2002
Based on the idea of SMB,this paper presents a set of middle-experiment equipment for chromatographic separation used to separate citric acid and so on.The design of control system based on PROFIBUS and soft-PLC.The configuration of the control system,the assignment and implementation of the tasks,the design concept of program satisfy the requirements of application.The scheme not only clearly reduces the hardware configuration and meets the requirements of the equipment ,but also helps make different technics research and acquires good effects.
