Title Design of the biodiesel refining system’s monitoring software based on SIMATIC WinCC
Abstract As a truly green fuel,the biodiesel is known for its environmentally friendly and renewable,and it is much pro-gaze at home and abroad.With the vigorous development of production preparation and the improvement of the refining system automation degree,biodiesel product quality and production efficiency is also of concern at the same time.This topic’s research is based on biodiesel refining system automation reconstruction project of one enterprise.
This paper uses SIMATIC WinCC software to design biodiesel refining process monitoring system,including:monitoring modules and function modules.The main designs of the monitoring module are monitoring interfaces of esterification reaction process,ester exchange reaction and washing process,flash evaporation and rectify process of supernatant liquid,flash evaporation and condensation process of lower liquid,and methanol recovery process.The function modules are:parameter setting,trend curve,report output and alarm display.At last,this project achieves the function of data communication system between the host compute’s monitoring system and direct controller PLC.
