In wood processing industries, which use electrical equipment in the production process, in most cases these are badly scaled or operate under inadequate conditions, resulting directly in industrial energy efficiency, which proves important because besides having technological innovation, also with practices and policies, aims to decrease power consumption. So in a wiring project should take into account the variables that influence energy efficiency. Thus this work has been reviewed and subsequently calculated some of these variables, such as active power, power factor and demand for the entire industry (global) and also for specific equipment, the chipper. The network analysis was performed in a wood processing industry in the city of Taquarivaí - SP, and evaluated these variables with a network analyzer and also by analysis on energy bills, which were found in both analysis levels below those found in literature. These factors are due to poor design, improper use, storage of equipment or even by characteristic of the production process, ie, the equipment running on empty because of the volatility of production

Este presente trabalho relata primeiramente o nascimento e desenvolvimento da indústria cultural brasileira em seu sentido integral, priorizando seu lado econômico, que se deu basicamente em 1930 com tentativas não tão bem sucedidas, mas que em 1960, com ajuda do governo militar (por interesses claros), se destacou e cresceu grandemente. Da mesma forma, pretendeu abordar aspectos que envolvem o amadurecimento e a estabilização deste mercado de bens no Brasil, de forma a descrever a situação atual, do século XXI, das firmas e empresas que integram esta cadeia que acaba por representar a cultura brasileira, principalmente na análise da qualidade de cada mercado de bens culturais inseridos dentro deste ramo da economia brasileira. Assim sendo, devido à complexidade e a profundidade do tema, esta monografia atreveu-se também a expor situações e fatos que levem o leitor à reflexão das influências que esta indústria causa na própria cultura brasileira, sendo capaz de modificar todo um cenário social, político ou econômico

Ethanol, the main automotive biofuel, has its production based on the fermentation of sugars found in biological materials and on the distillation of the alcoholic media formed during the fermentative process. Stillage is the main residue from ethanol production, containing a high organic loading in addition to acidic and corrosive characteristics. Considering the available technologies to treat stillage, we highlight anaerobic digestion, which allows the reduction of the impacts associated to pollutants loading of this effluent and the generation of energy from the methane gas produced in the process. Based on the high treatment efficiency usually associated to the anaerobic process, this work aimed to assess whether anaerobic systems applied to the treatment of stillage are energetically self-sufficient. First we evaluated the energy recovery capacity in an anaerobic reactor applied to the treatment of stillage resulting from corn-to-ethanol processing. The results indicated the great influence that a correct selection of electrical equipment and their respective operating periods have on the net energy balance of the anaerobic treatment. The high energy consumption of the heater would not allow the system to achieve a positive net energy balance – the maximum energy recovery would reach only 0.68% of the consumption. However, the replacement of the mixture equipment would result in energy gains ranging from 8.5 to 967.9% of the consumption. In this work we also assessed the efficiency of methane yields for a few studies and the correlation between some parameters of the anaerobic process. With respect to the methane yield, we noted that mesophilic systems tend to be more advantageous than the thermophilic ones (efficiency of 76.45 ± 22.51% vs. 69.40 ± 30.36%). Considering the study...

The growing demand for quality at competitive prices and fast production process put to the test function in the industrial Maintenance. The need for equipment with high availability to fit this fierce competitiveness makes maintenance becomes essentially reliable. Despite this current context, many companies still have an old view of maintenance, focused only on corrective services, and proposals for change are often neglected due to the sense of urgency day to day. Thus, this study aims to demonstrate through theoretical applicability of simple tool, but of great value in increasing reliability within the maintenance sector of an industry, applying the concepts of Reliability Centered Maintenance – RCM and Analysis tool Failure Modes and Effects – FMEA in equipment of a chemical company directly involved in the manufacturing process of the brake fluid, which this product is used in vehicles around the country. That way, you can identify the types, occurrence and criticality of each failure and evaluate assertively decision making for each device, avoiding unnecessary downtime and potential failures of the same

The cosmetic industry has presenting growth in Brazil and one way to support this demand is improving production and reducing waste. Wastes can be related to setup time, which is spent to support demand of product´s mix and volume. One of the methodologies used to reduce setup time is SMED (Single Minute Exchange of Die). This paper aims to describe and analyze the setup process in a production line in a cosmetic industrial branch, before and after the application of SMED methodology, highlighting good practices and difficulties in order to help other companies develop fast setup. The research method used was the case study. From the analysis of the implementation of the methodology on the company which is object from the case study was possible to summarize good practices, such as: the use of pillar E&T to store information about the training on the SMED methodology; creation of a multifunctional teamwork and involving different areas; creation of a “From-To” matrix. Difficulties were identified, such as: high and constant turnover of people who work on the shop floor; lack of discipline in filling the forms and by doing the setup activities that were standardized; lack of financial resources; lack of people´s availability in orer to conduct necessary meetings and trainings. Recommendations for other companies have also been proposed, such as: training of the team involved, before starting the project and a refresher training; standardization of training, forms and documentation of all steps of the project; create a multifunctional team; training after an employee, who is responsible for the setup, leaves the company

The reason of this work is perform a study about using of electrical energy to identify the opportunities through rational use of electrical energy. For that it was necessary perform an analysis of hired energy against consumption. Based in a guide of energy analysis were found the main consumers and verified the main problems, which generate excessive use of electrical energy in a plastic injection factory. It was also analyzed the painting line because there are some thermal equipment that use electrical energy. Based on the data obtained will be proposed ways to reduce the needless consumption and energy use of rationally and efficiently, in addition to re-evaluate the contracted demand based on the new policy of supplying and charging.It were also proposed thermodynamics solutions to reduce the energy consumed in thermal process

This work has as main objetive to analyze fiscal/tax collection of municipalities after the political-administrative decentralization in Brazil and its new role in this scenario, bringing up the competition for Decasa Sugar and Alcohol between the municipalities of Caiuá and Maraba Paulista in the context of expansion sugarcane cultivation in the Presidente Prudente Geographic Micro Region. The analysis has considered the geographic scales, in order to highlight the power relations on local/regional territory, determined by the Agroenergy Policy Guidelines in Brazil (2006-2011). The two municipalities have from the point of view economic dynamics, irrelevence, proven through the São Paulo Index of Social Responsibility (IPRS), maximizing the importance of the constitutional transfers, such as Participation Fund of Municipalities (FPM). Given this situation, we analyze the four taxes raised by the experts as the most impactful for municipal tax collection before the presence of sugarcane activity: the Territorial Urban Property Tax (IPTU), the Tax on Services of any Nature (ISSQN), the Tax Vehicles owned Motor (IPVA) and the Operations tax on the Circulation of Goods and on Transport Services Rendered Interstate and Intermunicipal (ICMS). It was verified, that only the ISSQN can be seen as an indicator increase in fiscal/tax collection before the presence sugarcane activity...
