Eficiência energética em uma indústria madeireira

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

Análise do consumo de energia elétrica e da eficiência energética em uma indústria de processamento de madeira

In the industries of wood processing (sawmills), where timber is sawn in equipment such as band saws, circular saws, trowel, thicknessers, among others, that mechanically transform this resource and use of electric motors, which are not unusually poorly scaled working or overloaded, often a factor that is not found in these industries and has fundamental importance in the production process is energy efficiency that is achieved by both technological innovation and through all the practices and policies that aim to lower energy consumption, lowering energy costs and increasing the amount of energy offered no change in generation. For both during the design of an electrical installation, both overall and in various sectors of the installation, investigations are necessary, considerations and uses of variables and factors that put into practice the theme of energy efficiency. Therefore, in this paper, these factors were calculated and analyzed for a wood processing industry (sawmill) in the municipality of Taquarivaí - SP, namely: active power, power factor, demand factor and load factor. Where they were small in relation to the literature, these events that occur when devices are connected at the same time and due to the conditions of processing the wood, where the engines have large variations in electricity consumption during the unfolding of the same, due to efforts with the load and idle moments between each machining operation in the equipment

Biorremoção de corante direto de efluente industrial simulado utilizando levedura liofilizada

One of the most primal ways of human work already known is the tessellation and ginning for the production of fabric and clothing - what used to be, back in those days, statement of power and status. The arrival of the Industrial Revolution - in the middle of the XVIII century at Britain - increased the textile industry production, and what used to be manufactured and hard to obtain, starts then to be produced in mechanical ways and large-scale. Despite all the boost given to the economy of an expanding capitalist market, it should be pointed out the consequences of this major industrialization, especially the environmental ones, more and more concerning nowadays. The emissions of waste - that sometimes could be toxic - in effluents can possibly contaminate the aquatic ecosystems, causing a huge damage to its fauna and flora, affecting therefore all the biodiversity, reaching inclusively the humans. To avoid these problems, a few strategies have been taking place in the attempt to eliminate - or at least reduce - the amount of dye found in the effluents, and as the textile industry constantly leaves waste, efficient methods - that present good results in a short period of time - with a low cost are needed. The present study will test the bioremoval capacity of yeast (Saccharomyces cerevisiae) in contact with dyes in a fix concentration, diluted in water with three different pH values. The tests will be done duplicate, and after the concentration analyses - made by spectrophotometry - it will be analyzed which pH shows major efficiency in the dye removal and what is the influence of the biomass in this process

Planejamento para a implantação da ISO 9001 em uma empresa do setor industrial

The fierce competitiveness of the current market and the sophistication of customer requirements made the commitment to quality a need within organizations. The search for quality has been carried out by the adoption of quality management systems, a formal organization that should be present throughout the organization, from the initial identification of market needs to the satisfaction of customer requirements. The methodology most commonly used for this purpose is based on the requirements of ISO 9001, latest version of 2008. Considering this scenario, was developed a case study in a small company of the industrial sector with the development of a plan for the implementation of ISO 9001. The proposed methodology involved the construction of a theoretical framework on the subject and the development of a case study with a qualitative approach. Initially, was applied a questionnaire to the representative of the organization about the company's operating procedures, activity logs held, current documentation, planning and resource management for the construction of an assessment about the adequacy of the company needs to ISO 9001. Were obtained as results the characterization of production processes and organizational structure of the company and examples of policy and objectives of quality, performance indicators, document control, system for visualization of non-compliances, among others. Finally, the benefits of adopting a quality management system based on ISO 9001 requirements for the company and its environmental issues such as increased process efficiency, less waste and greater profitability, were pointed out, and the conditions for effective certification in the future

Gestão para eficiência energética: levantamento e análise da produção científica divulgada em alguns periódicos das áreas de engenharia de produção e administração (2001-2011)

This research leads to a meta-analysis of scientific production in energy efficiency in industrial sectors, recorded in ten (10) leading journals in Administration and Engineering Production in Brazil, between 2001 and 2011. To this end, this scholarship was examined based on the following parameters: a) the total contribution and journal articles, b) methods used in studies, and c) the theoretical gaps to exploit. The diagnosis is that one infers: academic work in energy efficiency industries accounted for only twenty-nine (29) published articles, and only eight (8) have energy efficiency as a central theme of the work. Although the results still showed a rising trend in the number of publications since the last five (5) years analyzed showed 65.5% of all published files relating to energy efficiency. It contributes, therefore, the systematization of the academic production in the area of energy efficiency and business subsidies are provided for this field of research in Brazil.

Eficiência de um filtro de mangas no tratamento de gases oriundos de caldeira de queima de biomassa sólida

Atualmente a implantação de qualquer planta industrial que possa gerar impacto ambiental, ou até mesmo adequação de equipamentos já instalados para a não geração de poluentes ou geração dentro de limites adequados, passa cada vez mais por fiscalização rigorosa dos órgãos ambientais. A ventilação industrial tem sido e continua sendo a principal medida de controle efetiva para ambientes de trabalho que contenham dispersão de efluentes gasosos e material particulado de natureza prejudiciais, e baseado neste fato de relevância inegável é que se fundamenta este estudo. Um sistema de tratamento de gases com enfoque em ventilação local exaustora engloba vários equipamentos, e dentre eles o filtro de mangas é considerado um dos principais, pois sua função é a de efetuar a filtração dos gases proporcionando emissões dentro das tolerâncias dos órgãos ambientais, refletindo desta forma o objeto principal deste estudo de caso, a eficiência do equipamento. Especificamente neste estudo apresentam-se dados de eficiência do filtro de mangas em questão, componente de um sistema de desempoeiramento de uma caldeira de queima de resíduos sólidos. Foram utilizados dados coletados em campo em dois pontos do circuito do sistema, entrada do filtro de mangas e descarga de gases limpos, além de análise do elemento filtrante. As coletas e análises foram realizadas de acordo com as normas para a correta aferição dos dados gerados. Os resultados permitiram observar patamares de eficiência de filtração para os resíduos gerados na queima, demonstrando os cuidados a serem tomados no dimensionamento do equipamento para esta aplicação.

Análise da eficiência energética em indústrias madeireiras através da lógica fuzzy

This paper presents the application of fuzzy theory to support the decision of implementing energy efficiency program in sawmills operating in the processing of Pinustaeda and Pinuselliotii. The justification of using a system based on fuzzy theory for analysis of consumption and the specific factors involved, such is the diversity of rates / factors. With the fuzzy theory, we can build a reliable system for verifying actual energy efficiency. The indices and factors characteristic of industrial activity were measured and used as the basis for the fuzzy system. We developed a management system and technology. The system involves the management practices in energy efficiency, maintenance of plant and equipment and the presence of qualified staff. The technological system involves the power factor, load factor, the factor of demand and the specific consumption. The first response provides the possibility of increased energy efficiency and the second level of energy efficiency in the industry studied. With this tool, programs can be developed for energy conservation and energy efficiency in the industrial timber with wide application in this area that is as diverse as production processes. The same systems developed can be used in other industrial activities, provided they are used indices and characteristic features of the sectors involved.

Relação entre a concentração dos compostos fenólicos do mosto e a eficiência da fermentação alcoólica por subprodutos em processo contínuo

The objective of this work was to evaluate the relationship between phenolic compounds and alcoholic fermentation efficiency. The yield of sugarcanebyproducts (glycerol, acidity, and biomass) was determined in a continuous process at SaoManoel Sugarcane Mill, (Sao Paulo, Brazil) during the 2011/2012 harvest period. The Saccharomyces cerevisiae strain used as inoculum was the CAT-1. During the harvest, the endogenous yeast outcompeted the selected strain, hence eliminating it from the process. This research consists of a case of study on the ethanol production facility. FolinCiocauteau and methylene blue method was used to assess phenolic compounds. The efficiencyof the byproducts generated during the fermentation processwas calculated. Statistics analyses were carried out using Pearson correlation and its significance, by thet-test. We concluded that the phenolic compounds within the must could not be correlated to the byproducts’fermentation efficiency calculated during a continuous fermentation process.
