Title in Portuguese
Extração de óleo de soja com etanol e transesterificação etílica na miscela
Keywords in Portuguese
Biodiesel
Etanol
Extração de óleo
Abstract in Portuguese
Os modelos atuais de produção de biodiesel contam com a fábrica de biodiesel independente da fábrica de extração de óleo, causando desgaste logístico e falhas no sistema que, para não sucumbir, atrela matérias-primas desfavoráveis à produção, encarecendo o produto final, e perdendo competitividade no mercado com o combustível diesel. Para o trabalho foi montado um equipamento de extração que funcionou também na produção do biodiesel. Com a extração do óleo com etanol é possível conseguir uma miscela, que resfriada à temperatura ambiente, produz uma fase oleosa, capaz de gerar ésteres etílicos com rendimento bastante favorável. Para a produção do biodiesel o álcool utilizado foi o etanol, que por apresentar certa miscibilidade com o óleo, favorece a reação à temperatura ambiente. Ao final, foi utilizada a glicerina na fase de separação dos ésteres em lugar da destilação a vácuo, atingindo 92% de rendimento em massa, e um biodiesel de qualidade. Esse trabalho demonstrou a viabilidade técnica e produtiva de sistemas de extração e biodiesel conjugados, com menor demanda de energia, e a perspectiva de aproximar também a destilaria de etanol formando um complexo mais estabilizado e econômico

Abstract in English
The present models of biodiesel production is based on biodiesel plants regardless of the oil extraction industry location, causing many logistic problems and fails on the system, which in order not to go unactive, adopts unusual fat sources, raising the costs of the final product, and losing market competitiveness to diesel fuel. In this paper, we developed an extraction equipment that can be also used for the production of the biodiesel. Resulting from the oil extraction with ethanol it is possible produce a miscelle that cooled to ambient temperatures generate an oily phase, able to yield ethyl esters efficiently. In order to produce biodiesel ethanol was the alcohol used, that due to a certain miscibility with the oil, favored the reaction at ambient temperature. At the end, the glycerin was used, instead of vacuum distillation, in the esters separation, with a 92% of mass efficiency, and a quality biodiesel. This work demonstrated the technical and product viability of conjugated extraction and esterification systems with lower energy requirement, and the perspective to be close to the ethanol distillery becoming a more stable and economical complex
