DESIGN OF A MONITORING AND CONTROL SYSTEM IN THE BIODIESEL PURIFICATION PROCESS

Methyl esters in the transesterification process containing impurities can cause problems when they are used and stored. Some things that are strictly related to the biodiesel purification process are the monitoring and control process. A real-time monitoring system with multiple sensors and controls in the purification process is needed to ensure temperature, pH, level and dielectric can be achieved in optimal washing and drying times. This study aims to provide a conceptual model design of monitoring and control systems in the biodiesel purification process through a needs analysis using Business Process Modeling and Notation. The conceptual model in the biodiesel purification process that was built with BPMN produced four stakeholders who integrated each other and outlined each task and rule to optimize each function. The formulation in the monitoring and control system recommends the installation of Arduino and Xbee-based sensors that can be accessed through the Local Area Network. The system has been designed to facilitate the monitoring process in real-time and accurately.
