Aspectos técnicos e ambientais da incorporação de novas tecnologias no setor sucroalcooleiro: produção de hidrogênio e gaseificação do bagaço

The purpose of this work is to study the incorporation of hydrogen production (Case A) and the process of gasification of sugarcane bagasse associated with combined cycle gas turbine and steam turbine (Case B) for Distillery Pioneers process. These technologies can be used to improve the energy supply in the sugarcane mill. Initially the processes for obtaining sugar and ethanol from sugarcane is discussed, with a theoretical introduction to hydrogen, the process of steam reforming and gasification of biomass (bagasse) by inserting a turbine associated with the recovery boiler gas. Subsequently makes up the energy and exergy analysis of the incorporation of the above technologies. In end stage makes it an ecological analysis considering or not the carbon cycle (photosynthesis), to determine the levels of emissions of pollutants, carbon dioxide equivalent, indicators of pollution and ecological efficiencies associated with technological developments proposed. It is concluded that hydrogen production by steam reforming of ethanol and gasification of bagasse are viable alternatives from the point of view of technical and environmental applications in the biofuels industry, contributing to the development of the sector in the country

The dynamics of the health services sector can be seen in studies of geographical features as analysis on the quantity and quality of médical and hospital services provided and the demand or need sensed by the population, whether the public sector, whether private sector within a defined portion of space, in analysis in this study, the Administrative Region of Barretos, State of São Paulo. This study seeks to better understand the dynamics of the health services sector (Public and Private) in the production of urban space of the Administrative Region of Barretos, for it will be reviewed, in particular, the Cities Health Centers, Bebedouro and Barretos. Also proposes through this, try to clarify the central regional Barretos and Bebedouro in the context of health services

Incorporação de novas tecnologias no setor sucroalcooleiro: produção de hidrogênio e aumento da oferta de eletricidade

This work studies the incorporation of new technologies in the sugarcane sector. Are considered the ethanol steam reforming and the gasification of sugarcane bagasse(by-product) processes associated with combined cycle systems (Gas Turbine + Steam Turbine), aggregating hydrogen production and increased electricity supply in the sector, respectively. To verify the technical feasibility of the incorporation processes was performed a thermodynamic analysis, considering data from a typical Brazilian Sugar Cane Industry. In another step the economic viability study of the hydrogen production process was made, with consideration on hydrated and anhydrous ethanol steam reform, comparing the cost of hydrogen production. Also considered studies of economic engineering of the gasification process and the generation of electricity associated. As conclusions, it follows that the ethanol steam reforming is a great alternative for hydrogen production, presenting production cost relatively low, especially when is considered the steam reforming of hydrated ethanol. For the gasification process associated with combined cycle, can be observed an increase of 8.56 times of the electricity production in the sugar cane industry, indicating a positive annual saving when the sales price of the supply electricity is greater than 0.070 US$/kWh. Finally it can be concluded that the incorporation of these new processes allow greater profitability and operational flexibility of Brazilian sugarcane mills

Estudo das características fluidodinâmicas do bagaço de cana de açúcar para aplicações da gaseificação no setor sucroalcooleiro

In this work is studied the fluid dynamic characteristics of sugarcane bagasse for gasification applications and use of syngas in the sugarcane sector. This is an experimental work, which is initially performed the particle size separation of sugarcane bagasse particles, using appropriate equipment. Through the experiment is possible to determine the average diameter of particles pomace typical sugarcane mill. The equipment used for the grading sieve separation assembly consists of several dimensions, arranged vertically and which shows adequate for good separation from the pulp. Later, it makes immediate analysis for the determination of moisture, ash, volatile materials and fixed carbon. The study also determines the gross calorific value and allows analysis of densities of particles of sugar cane bagasse. Also studied the bagasse morphology using electron microscopes, where it was possible to visualize the geometry of the particles of bagasse. The use of Electronic Scanning Microscopy (SEM) provided better understand the morphology and particle size measured by using photography methods. Two methods for determining the sphericity of the particles were also used. The experiments carried out using appropriate standards and specific equations, allowing compare the present results with the values found by several researchers. Subsequently, fluid dynamic simulations were performed for the determination of porosity and minimum fluidization velocity theoretical. It follows that the sphericity and porosity of the bagasse particles influence the minimum fluidization velocity of biomass

A reprodução capitalista no setor habitacional e as transformações no espaço urbano: o caso do Jardim Letícia (Leme-SP)

This paper discusses urban space focusing on the housing sector, the capitalist reproduction and some changes occurring in that space as a result of the dynamics of the real estate sector and interests of financial agents, developers and urban land owners/speculators. The changes imposed to cities value abstract spaces over concrete ones, showing the unbalance between the interests of agents, who have in view the market, and those of dwellers, who live daily in such areas. Based on these reflections, a case study was carried out in the Jardim Letícia neighborhood in Leme city (state of São Paulo) in order to understand the space production and reproduction in that area, analyze some of the main problems faced by local people, and identify some agents involved in the 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
