Ultrasound Sensor for Process and Fouling Monitoring in Emulsion Polymerization Processes

In order to produce emulsion polymerization in continuous systems, it is necessary to monitor the process very precisely. To do so as energy- and cost-efficiently as possible, monitoring of fouling is essential to perfectly adjust cleaning cycles. Therefore, an online measurement method is needed, which is not commercially available for these applications. In the present work a measuring system is developed, which can be integrated in continuous systems, and which can measure the fouling and evaluate it in real time. In addition, the reaction and substance properties in the process are to be monitored. The measurement system is realized with a single channel ultrasound echo measurement.
