Seleção de motobombas para o setor sucroalcooleiro

This work has the purpose to explain how the sugar and alcohol sector works, detail all the processes which uses pumps and assist in the selection and specification of pumps attached with engines, that will make part in important industry processes in the manufacture of sugar and alcohol. A bibliographic revision about the working of sugar and alcohol sector and about pumps were made to help the analysis of a case. This case had the purpose to analyze the selected pumps that were part of a initial project of an industry which aimed a future expansion. The pumps that were selected to made part of the initial project were over dimensioned and were operating out of the best performance point, making the pumps inefficient because the expansion didn't happened. The solution was to select another pump with bigger performance and less power consumption to have a decrease in the energy consumption and in the operational costs of the industry and using the extra electric energy in the industry or selling it

Análise crítica de um vaso de pressão do setor sucroalcooleiro

This study aims to evaluate structurally a heat exchanger that has been in operation since the mid-60's and was built COSAN for operation in one of its sugar production plants in São Paulo, this equipment as well as many similar devices are operation in plants throughout Brazil, and thus to be acquired by large corporations as in the case of COSAN, pass the scrutiny of inspection work, and work such as recalculations in the latter case in structural evaluations to verify the possible need for adjustments to project or operation and thus ensure the structural integrity of the equipment. To this were first done field survey using techniques of NDT and NDT's for determining the thickness of the main parts of the equipment, made the revaluation dimensional and existing project and considering the loads operating performing the characterization of the equipment as specified in the standard regulatory number 13 - NR13 and the other for this type of equipment and finally an analysis using a static approach, as an analysis tool using the finite element method

O setor sucroalcooleiro no Pontal do Paranapanema: uma análise a partir do licenciamento ambiental

The development of the sugar and alcohol sector and its sugar cane cultivation has been given in an accelerated way in Pontal do Paranapanema, mainly from the last decade, and with this has taken quick changes in the dynamic socio-economic and environmental of the region, further accentuating some conflicts and dilemmas social and environmental legacy. This work was done in order that these issues are further explored, that of moving towards a greater theoretical-scientific maturity, and even has a better apparatus to support measures (corrective or preventive) that show required anti such conflicts. For this purpose, we used the environmental licensing as a means of doing this analysis, since it is one of the main instruments of control/ regulation of the State against the development of activities of the sugar and alcohol sector. We also used a little of the vast potential of information that is contained in the environmental agencies. In this case, we used six Environmental Impact Study / Environmental Impact Report (EIS /EIR), six Preliminary Environmental Reports(PER), five Characterization of Enterprise Memorials (CEM), among other documents /studies present there. Some of the information, organized and made available in this work, has even greater potential to be exploited. It was also made an essential literature survey and of the laws related to licensing and alcohol and sugar sector

A territorialização do setor sucroalcooleiro no Pontal do Paranapanema: estudo de caso do município de Martinópolis - SP

The sugarcane agribusiness has expanded by Brazil in recent years, especially with government incentives, which funded the construction and expansion of distilleries and sugar mills and alcohol throughout the national territory, as well as the expansion of the cultivation of sugarcane sugar. The state of São Paulo is the main focus of expansion in the sector, and its municipalities impacted significantly. The Pontal do Paranapanema is one of the last frontiers of cane sugar in the state, so that the culture has brought transformations mainly from 2003. Thus, we take the case of the municipality of Martinópolis analysis, which investigated some transformations in economic dynamics from 2004, the year he began the deployment of Plant Athena. For this, we conducted interviews with several subjects and analyzed statistical data from IBGE, LUPA, MAPA and CANASAT. Aware that these changes are limited to the capitalist market economy, we analyze the benefits and disadvantages brought by the activity of the plant for the population as part of economic growth characteristic of this scenario, taking it to the very prospect of local subjects. Alongside this growth, all other forms of inequality and exploitation of surplus value also grow which is not understood or perceived by residents. Hence the need to confront views and discourses on development promoted by the alcohol sector

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

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
