The purification of biodiesel of the production process by transesterification of oils and fats require the removal of glycerin waste. It presents a strategy for separation of glycerin dispersed in biodiesel using an optimized hydrocyclone of the Rietema family. As calculation methodology correlations that lead to the sizing diagrams were converted into mathematical models involving significant dimensionless numbers. It presents a strategy for separation of glycerin dispersed in biodiesel using an optimized hydrocyclone of the Rietema family. They had been simulated and analyzed the conditions of separation of the mixture biodiesel-glycerin, integrant stage of the process of production of this biofuel of separation of oils and fats, in optimized and not optimized operational conditions. The optimization strategy was the use of economic and geometric correlations, which had led to the attainment of a minimum cost. One of the stages most important of the process of production of biodiesel is of its purification. One hidrociclone of the conventional type was considered for the related stage. The used strategy for elaboration of the objective function was composed of three terms: cost of acquisition, cost of operation and the associated cost does not collect of biodiesel, all as function of the diameter of the equipment. As programs of calculations for sizing and optimization the electronic spread sheet Excel and its tool had been used to solve. The results had shown that the strategy and optimization had supplied values of not optimized sizing very next to the ones of condition, demonstrating that the same one can be used as reinforcement, at a time where the economic criteria are important justifications of investments in the improvements of the productive processes.
