Reuse Concept - Vital Segments in a Clean in Place Project

Abstract: The aim of this project was to examine if it is feasible to develop and apply a reuse concept regarding clean in place (CIP) processes. The concept is based on different topics such as lim-itation, structure, future and reliability. Three CIP processes were chosen to represent the wide variety of cleaning processes available to the food and pharmaceutical industries, Single use Food, Recovery Food and Single use Pharmaceutical. Each were developed according to a pre-determined structure in order to cover all chemical engineering aspects of a project; process description, process flow diagram, calculations, heat and mass balance, piping and instrumen-tation diagram, component list, chemicals as well as sales and promotion. The process description resulted in an overview of main features for each system. Heat and mass balances describes how the content and energy of the different flows are changing throughout a cleaning cycle. Differences and similarities between the examined systems are lucid through the P&IDs. The component list resulted in facilitation of documentation, design, purchasing and installation for the project. Quotation regarding the three systems were calcu-lated and combined with reuse some costs are reduced or excluded. In order for a reuse concept to work, the CIP process must be sold in sufficient volume. Broadening the customer base from an international perspective is the best way to facilitate, maintain and sustain a recuse concept. Time has been a limiting factor due to the versatile variation of systems included in the field of CIP. The sectioning concerning the three main systems has tough delivered a secure and fun-damental base considering further work. One important segment, not included in the reuse con-cept is automation. The lack of automation is leading up to a reuse concept not covering the entire spectra. A corrective action is to use an automation engineer in order to get as much as possible of the software ready for being handled in a reuse concept. A CIP project have an obvious extent when studying application and area of usage compared with several other tech-nologies. This is the logical explanation for why CIP projects are a good area trying out a reuse concept. Transferring the reuse concept to other projects could include problems not covered by this concept. A larger area of application are making unexpected events more realistic and project frames more obscure. Studying former projects in each area over time combined with inspiration from this CIP reuse concept as a foundation will hopefully generate a more efficient future way of working. A final conclusion regarding this project is in accordance to the Pareto principle, the reuse concept is making up 70 % of the results within 30 % of the time. This fact is pin pointing at the level of reliability, main segments in a CIP project are handled and in-cluded even though adaptions are requiring much time.
