Estudo de confiabilidade aplicado ao aumento da disponibilidade da instalação de um laboratório de uma indústria alimentícia

Abstract

This work aims to present a feasibility study for the implementation of electrical solutions, in principle the IT grounding system with current monitoring, which optimize safety and reliability aspects of an industrial installation located in the municipality of Maranguape in the state of Ceará. This study was motivated by verifying the low reliability and safety of the industrial electrical installation of the Agricultural Cooperative of Maranguape, as well as the limited investigation of solutions that aimed to optimize these topics of the electrical installation. The work included the characterization of the situation of the laboratory sector, the modeling and calculation of the operational reliability of the laboratory sector, the analysis of the implementation of the IT system and the retrofit, and the comparison of these solutions. The choice of the plant's industrial laboratory was due to the history of failures and bearing in mind that it carries out the physical, chemical and biological analyzes of all batches manufactured daily, via the sampling process and, therefore, can be characterized as a vital sector. At the end of the work it was possible to conclude that, for the case studied, the IT grounding system project presented itself as a technically implementable solution, presenting itself as a reliable predictive measure for a sector whose operation is vital for the industry's production process however, given the verification of the problems currently existing in the installation and in view of the considerable difference in the investment cost between the solutions addressed, the recommendation was made to adopt the retrofit of the electrical installation as the best solution.
