The project premise was to create a new temperature control scheme for an emulsion polymerization process at the pilot scale with intentions of implementing the system into a production facility in the near future. The data was collected using electronic instrumentation at a current emulsion polymerization pilot plant facility in real-time and saved in a Microsoft Excel format. The control scheme was based on three parameters: the rate of change, temperature dead band around the set point to determine heating or cooling, and a jacket fluid clamp temperature. After research and experimentation on actual emulsion polymerization batches it was determined that a rate of change of +/- 1°F/minute was ideal. The dead band was set at +/- 2°F of the set point and the jacket was clamped at +/- 17° F of the set point. Accurately controlling the temperature of incremental emulsion polymerization batches helps to improve particle size control and product quality.
