In this research work, to reduce the separation time of glycerin, increase in efficiency and purity of recovered methanol and pure biodiesel production, a novel biodiesel processor system is designed, fabricated and evaluated. In fabricated system, batch type stirred tank reactor (STR) with a capacity of 70 liters in which to more efficient mixing, two methods of mechanical and hydraulic mixing has been provided. In order to increase the purity and efficiency of methanol recovery process in designed system, facilities in the vacuum distillation method is provided. One of the innovations used in this system in addition of sediment glycerin separation, is utilizing electrostatic Coalescing method in separation of glycerin in which the high voltage / low current is used. Another innovation used in this system, is possibility of using ion exchange dry wash by absorbing column and magnesol powder as filter aid. All tanks, pumps, piping, valves are made from 316 Stainless Steel to ensure no erosion. Biodiesel produced by fabricated system showed close value to the requirements of biodiesel standard.
