Implementação de um tuboexpansor na refinaria do Planalto Paulista – REPLAN com objetivo do aproveitamento da energia contida nos gases residuais do FCC – Fluid Catalytic Cracking na geração de energia elétrica

The steel type AISI 4130 (ultra-high strength steel) is an alloy of low carbon and its main alloying elements are chromium and molybdenum, which improves the toughness of the weld metal. It has numerous applications, especially where the need for high mechanical strength. It is widely used in equipment used by the aviation industry, such as cradle-tomotor, and this is the motivation for this study. Cots are of fundamental importance, because the engine supports and maintains balance in the fixed landing gear. This equipment is subjected to intense loading cycles, whose fractures caused by fatigue are constantly observed. Will be determined the effects caused by re-welding the structure of aeronautical equipment, and will also study the microstructure of the metal without welding. The studies will be done on materials used in aircraft, which was given to study. The results provide knowledge of microstructure to evaluate any type of fracture that maybe caused by fatigue. Fatigue is a major cause of aircraft accidents and incidents occurred, which makes the study of the microstructure of the metal, weld and re-solder the knowledge essential to the life of the material. The prevention and control of the process of fatigue in aircraft are critical, since the components are subjected to greater responsibility cyclic loading

Técnicas de energia elétrica sustentável aplicadas em edificações

One of the majors concerns in society today is to decrease the environmental impact caused by human activities and natural resource exploration. From this need to be more careful with the environment arose, in the field of civil construction, the term sustainable building. Projects that use natural resources rationally, without ceasing to bring comfort and functionality for customers, are becoming more a reality. This paper presents the share of electric energy in a sustainable building, with the analysis of the available renewable energies used in a project, presentation of new constructive techniques and technologies that are constantly emerging to achieve greater energy efficiency, with an appropriate use of energy received, also a decrease of the energy consumed by some devices present in a residence or business

Implementação da metodologia TPM em uma indústria do setor de higiene pessoal, saúde e beleza

This work presents a project of Action Search in a consumption industry of the sector of personal care, health and beauty. Following the implementation steps of Autonomous Maintenance Pillar of TPM methodology, stands for Total Productive Maintenance, this work aims to ensure the advancement of some machines in a production line of the company to the next steps of the methodology implementation, demonstrating the results achieved by the TPM. In the company in question, the TPM has been implemented in the past but lost strength over the years and some of its concepts were abandoned, producing then a drop in the equipments efficiency, increased wastes and breaks in the processes, as well as loss in product quality. Then, the need arose to restart the implementation process from the beginning, to strictly follow all the steps of the methodology, ensuring increased efficiency of equipment and processes. Through training and a changing in the company culture, it was possible a joint effort between Operation and Maintenance in order to enhance the knowledge of the operators on their machines. Initially, it was developed a general cleanliness program of equipments so that it could be possible to find the anomalies in the process. Subsequently, operators and maintainers were trained to detect anomalies, enabling equipments to work under their basic conditions of operation and subsequently building provisional standards of equipment cleaning, lubrication and inspection. Through the improvement presented by some indicators such as OEE, wastes, bankruptcies and unavailability, it was proved the importance and the positive effects of TPM implementation in manufacturing

Estudo da indústria farmacêutica brasileira: a queda das patentes e entrada dos medicamentos genéricos

The objective of this study is to examine the pharmaceutical industry and changes that the fall of patents and entry of generics may cause in the price and consumption of drugs. Thus, there is a brief discussion about the global pharmaceutical industry, from its origins to the present day, showing in particular the case of the United States, today considered the largest industry in this sector. From this, the work seeks to address specifically the Brazilian industry and its regulation. Since the generic law implementation, the participation of this type of medicine has grown significantly in the country. Because they have always been lower than prices of their brand, the cost of treating disease is reduced, which makes generic drugs represent an improvement for consumers in terms of welfare of society

A energia solar fotovoltaica e seu mercado no Brasil

A energia solar fotovoltaica tem se destacado como uma opção de fonte energética limpa e muito confiável. No entanto, é a Europa que detém a maior representatividade fotovoltaica no mercado mundial, indo contra o senso comum de que seriam os países pertencentes ao Cinturão do Sol aqueles com a maior capacidade instalada. Apesar das condições favoráveis para o desenvolvimento da fonte, o Brasil possui um mercado muito deficitário, contando apenas com poucos projetos de incentivo para levar eletricidade para comunidades carentes afastadas dos centros de geração ou das redes de distribuição. O país carece de programas exclusivos para a energia solar fotovoltaica que proporcionem incentivos ao mercado, a fim de impulsionar a indústria local e estimular o investimento no longo prazo para a maior diversificação da matriz energética brasileira. Assim, o presente estudo buscou ilustrar e analisar o cenário do mercado brasileiro atual da energia solar fotovoltaica, apresentando seus saldos comerciais com os quatro principais mercados mundiais para a fonte: Europa, EUA, Japão e China, segundo os dados disponibilizados pelo banco de dados Aliceweb para os itens 8541401, 8541402 e 8541403, classificados segundo a NCM
