Abstract

Industrial installations with corrosion resistance and asepsis requirements are designed and built based on strict criteria to ensure the sterilization of industrial processes and product protection. The deterioration of the equipment and consequent contamination of the product often occur due to degradation by corrosion of the welded joint, since the welding procedure qualification standards require only mechanical strength test and the corrosion resistance is not evaluated properly. Thus, this research and development project aims to evaluate the parameters and determine the optimal conditions of use of a portable electrochemical microcell for commercial applications. The methodology consists in detail of the mechanical design of the microcell, and this, industrial chemical processes studies will be conducted to better knowledge about the application of microcell environment. Tests and simulations will be conducted to support the technical development and consolidate the mechanical design. Another highlight is the participation of a large industry with aseptic requirements in industrial processes that will serve to feed the project data on the application of microcell, assist in the scope of services and define the application model microcell in an industrial environment. With the completion of Phase 1 of the PIPE project the company will have the electrochemical microcell design specification for commercial application, technical feasibility and scientifically, designed with a focus on industrial processes of customers and the presentation of results from the perspective of maintenance and engineering managers who will be the users of the results from the use of electrochemical microcell.
