Chemical Engineering Clean-in-place (CIP) technology allows complete systems in manufacturing to be cleaned without disassembly. Advances in CIP technology can significantly reduce change-over times, which can save a company time and money. Stemming from the dairy industry, CIP technology has expanded to various industries including pharmaceutical and personal care. Most of the CIP technology improvements have been in processing. As companies are trying to improve productivity, they seek to optimize their current cleaning processes, reduce their water use and increase compliance with industry standards. This thesis focuses on potential CIP improvements for an industry partner (who wished to remain anonymous) who is currently trying to improve their processes in the packaging department. An engineering analysis was completed, and three steps in the CIP process were found to have the largest opportunities for improvement. These steps included the cleaning of the transfer pipe, buffer tank, and filling machine. The initial engineering analysis revealed improvement opportunities for the buffer tank and filling machine steps, but deeper analysis was needed to understand clearing the transfer pipe. Consequently, a model was created, and this model is the basis of this thesis. The model is based on simultaneous solution of the equations of energy and continuity. The Crank Nicolson (CN) and Control Volume Finite Difference (CVFD) methods were used to solve simplified forms of the equations of change to estimate numerically the total time needed to clear the transfer line. The results of this study suggest that the industry partner could save 5,640 L of water and 18.3 minutes per cleaning cycle. Although this analysis was on a specific CIP process for packaging equipment in the personal care industry, the principles can be applied to other industries and processes. 2020 English text University of Cincinnati / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ucin1613747962470201 http://rave.ohiolink.edu/etdc/view?acc_num=ucin1613747962470201 unrestricted This thesis or dissertation is protected by copyright: some rights reserved.
