RESUMO
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
