Design Of Control System For Reboiling Part Of Distillation Process

This paper selects the control system for re-boiling part of distillation process for major research. The control scheme is determined according to the influence of the relevant parameters on the distillation process. The hardware part uses the Siemens S7-200 series PLC as the main control machine. The lower position machine uses STEP 7-Micro / WIN programming software, and writes the control program through the ladder diagram. It combines the PID algorithm and single closed-loop control to complete the field data collection and processing and communication with the host computer. The host computer uses the configuration king named kingview6.55 monitoring system software to complete the automatic control system monitoring.
