Estudo e análise de sistemas de refrigeração industrial integrados a plantas de processo químico

This work approaches the analysis of industrial refrigeration systems applied to a chemical processing industry that, in this case, consists of refrigeration machines, cooling tower system, cold water system and brine system. In this study it is highlighted the function and characteristics of different systems, including the main components, the most important features, their functionality and best practices. The motivation for this work is the fact that refrigeration systems are essential in many industrial processes, presenting a high energy consumption that is related to a significant parcel of production costs. It has aimed to understand the case studied in order to evaluate the energy efficiency of systems and to compare with Carnot efficiency and best available technologies. The assessment aims to identify irregularities, find opportunities and propose solutions that increases the performance of equipment and the overall system efficiency. Therefore, the studies intend to reduce the operation costs and generate gains for the company

Análise do funcionamento e a evolução de um programa de sugestões de ideias e seus benefícios

The competition for markets have created extreme challenges for companies that need an efficient management system. The transformational system involve all the employees in the task of eliminating waste, add value to products, reduce variations in processes, increase reliability and discover customer needs. The collaborative management is one of the focuses of this research. It was based on the analysis of the Fleury's suggestion program called Central de Ideias, The Fleury Group is one of the most traditional organizations of medical and health in the country. We pointed out the evolution of the program and we also showed the results of the changed of the management tool ideas. An extensive theoretical study was conducted in order to enhance the benefits that a suggestion system provides to the organizations. The Programa Central de Ideias has saved millions for Fleury and it has been made processes more efficient. The increasing of employees participation, the improvement of the internal communication and the refinement of the quality services are one of the suggestion system benefits

Análise de viabilidade de implementação de um centro inteligente de motores

Across the industry, regardless of the activity which is intended, the electricity distribution must meet the current and ever growing needs of the market, aiming at reliability and process efficiency. The energy must not only be available to ensure continuity of operation, but also to avoid the costs incurred due to deficiencies and failures. The tendency to migrate to intelligent systems is undeniable and this thesis will be analyzed the advantages that made this kind technology essential, focused on the analysis of the motor control center and as sturdy equipment fit to the concept of intelligent panels. The case study compares in a real scenario the acquisition of a system of low-voltage electrical panels comparing the cost to purchase the same set of panels made with and without the concept of intelligence
