Item Aproveitamento do bagaço de cana-de-açúcar para produção de etanol de segunda geração(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-04-05) Santos, Carlos Gabriel Inácio Guedes; Leitão, Ana Laura Oliveira de Sá; Leitão, Ana Laura Oliveira de Sá; Rocha, Martha Suzana Rodrigues dos Santos; Santos, Taciana do NascimentoThe sugar and ethanol industry has a prominent place in the Brazilian economy, because of that, Brazil is responsible for generating a large volume of waste. About 5 to 12 million tons per year of bagasse are produced due to the production of sugar and ethanol. All this may become an environmental pollutant if residues are improperly disposed of. Therefore, it is valid the effort for new alternatives of use for these residues. In this context, second-generation ethanol (2G) has proved to be an attractive alternative, since it has environmental advantages, as it is produced from lignocellulosic residues. Thus, the aim of this work is to present, through a literature review, the potential of bagasse of sugarcane to obtain 2G ethanol, describing all stages of the production process. For this, a search was made on websites, scientific articles found on Google Scholar, as well as monographs, dissertations and thesesItem Cana-de-açúcar e a produção de etanol(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-03-18) Moreira, João Igor Andrade; Cunha, Simonise Figueiredo Amarante; Cunha, Simonise Figueiredo Amarante; Cavalcante, Maria da Conceição Matos; Tavares, Andreia Macleybiane GoisThus, the objective of this work is to present the production of ethanol from sugarcane (Saccharum spp), its history in Brazil, cost reduction, ethanol production process, types of ethanol and by-products produced. Compared to other countries, Brazil has some advantages in ethanol production, such as mastery of the entire production process, plenty of land, skilled labor and worker safety. Usually, ethanol production involves the following steps: milling, juice treatment, fermentation and distillation and in some cases dehydration processes. The first generation of ethanol is a traditional system that produces ethanol from sugarcane juice, and which still leads the sugar and ethanol industry and its production by-products such as vinasse, bagasse and filter cake, which are of lower cost for the industry. As for anhydrous ethanol, in addition to the aforementioned stages, there is also the dehydration stage. Production is a positive perspective, given the increase in sales of flex-fuel vehicles, increased consumption and exports of sugar and ethanol, increased domestic consumption of anhydrous ethanol and hydrated and expansion of production, in this perspective it was possible to perceive the importance of the study of the sugar-alcohol area to understand how the process that transforms glucose into ethanol is carried out is of paramount importance.Item Impactos ambientais causados através da produção do etanol(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-03-18) Santos, Adrielle; Cunha, Simonise Figueiredo Amarante; Cunha, Simonise Figueiredo Amarante; Tavares, Andrea Macleybiane; Silva, Wcleuton OliveiraIt is known that with the need for independence from oil and the search for fuels that were less polluting, the Proálcool was created, with the objective of encouraging the production of ethanol. Thus, ethanol is known to be a sustainable fuel alternative, in which it is generated from renewable sources. However, it is observed that during the production of ethyl alcohol some impacts to the environment are triggered. Therefore, this work aimed to analyze, through a literature review, the environmental impacts caused during each stage of agricultural and industrial production of ethanol. Therefore, impacts such as reduction in soil quality, soil and water bodies pollution by the exacerbated use of pesticides and fertilizers, in addition to atmospheric pollution and loss of biodiversity resulting from the burning, were identified, finally, soil and water pollution were also found due to incorrect disposal or uncontrolled use of residues and effluents from stages of the industrial process of manufacturing ethanol.Item Parâmetros de qualidade relacionados à produção de etanol anidro e hidratado na usina Caeté - Unidade Marituba(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-04-11) Rolembergue, Kawany Monteiro; Leitão, Ana Laura Oliveira de Sá; Leitão, Ana Laura Oliveira de Sá; Oliveira, André Luiz dos Santos; Santos, Taciana do NascimentoEthanol production in Brazil is mainly from sugarcane. The elaboration of this product - crucial for the national economy - is carried out in the sugar-alcohol plants and for commercialization it is necessary to maintain the quality of production. Therefore, it is essential to monitor the quality at each manufacturing stage. Hence, this report aims to present and describe the lessons that were learned during the internship at CAETÉ S/A MARITUBA plant, producer of ethanol and other sugarcane derivatives, emphasizing the quality parameters related to the production of anhydrous and hydrated ethanol at the plant. Fermented must, feed must, unleavened wine, water, CO2, concentrated milk, treated milk, final honey, vinasse and vat are the samples analyzed in order to maintain the industry parameters. The analyzes include Brix, pH, acidity, conductivity, T.R.S., T.R.R.S., alcohol contente and yeast percentage, which aim at the stability and quality of the final product. The internship triggered the curiosity to learn the role of a chemistry technician at the plant, being of great importance for the consolidation of this professional career.Item Processo de produção do etanol de segunda geração a partir de resíduos agroindustriais(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-03-31) Ferreira, Carlos Manoel Guimarães; Rocha, Martha Suzana Rodrigues dos Santos; Cabral, Mirelle Márcio Santos; Cabral, Mirelle Márcio Santos; Rocha, Martha Suzana Rodrigues dos Santos; Cunha, Simonise Figueiredo AmaranteAs a result of the scarcity of fossil fuels that have lasted for years, the renewable energy sources are getting worse in the present century, being a promising and more sustainable alternative in relation to the environment. With the growing demand for ethanol as a fuel, research has been developed to increase the production of this product without increasing the plant’s cultivation area. Thus, second generation ethanol – 2G arises, being produced through waste often discarded from other cultures. These residues go through steps to provide fermentable sugars and are then fermented by yeasts. The major obstacle of this product is the high cost of production that makes the process unfeasible. Thus, the present work aims to describe and analyze the stages of the 2G ethanol production process, through bibliographic research, also addressing its main raw materials. It was possible to conclude that second-generation ethanol is an advantageous product, but it still needs to be developed so that the process becomes economically viable.Item Processos industriais da fabricação de álcool na usina Caeté S/A - Unidade Marituba(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-04-27) Honorato, Micaele dos Santos; Rocha, Martha Suzana Rodrigues dos Santos; Rocha, Martha Suzana Rodrigues dos Santos; Cabral, Mirelle Márcio Santos; Silva, Wcleuton Oliveira; Santos, Lenilson de AlmeidaLa caña de azúcar tiene la característica de ser una planta delgada, con hojas grandes y puede alcanzar hasta los seis metros de altura. Es a través de él que se inicia la producción de azúcar y etanol, productos esenciales para la vida humana. Se originó en la isla de Nueva Guinea y junto con la migración humana se extendió por todo el mundo con el tiempo. Llegó a Brasil en 1520, tras la llegada de los portugueses. El etanol es un compuesto orgánico, de color transparente, tóxico e inflamable, soluble en agua y de fuerte olor. El mismo es un producto derivado de la caña de azúcar, maíz, avena, arroz, cebada y trigo. Producto muy importante para la elaboración de bebidas alcohólicas, industria farmacéutica, combustibles y entre otros. Brasil comenzó a lograr la autonomía en relación con los combustibles líquidos y la reducción de costos en su producción, lo que convirtió al etanol en un biocombustible competitivo con relación a la gasolina, cubriendo los mercados internos y externos. Por lo tanto, es de gran importancia en el proceso de desarrollo del país. Por lo tanto, el presente trabajo presenta de forma resumida los pasos del proceso del etanol en la industria sucroalcoholera, así como los parámetros de control de calidad adoptados por la Usina Marituba. El mismo presenta informes de experiencias de una pasantía supervisada, así como análisis de laboratorio realizados a lo largo de la misma.
