biodiesel washing

Washing biodiesel will remove contaminants left over from transesterification. These contaminants include soap, catalyst, methanol, and free glycerin. There are different techniques for biodiesel washing, including agitation washing, mist washing, and resin based biodiesel washing. In this manner, it is just fitting to have more consideration on the matter of biodiesel washing. This is on account of biodiesel is a renewable fuel source and is extremely sheltered to utilize with regards to ecological assurance. Excess methanol is suspended in the unwashed biodiesel. The soaps, catalyst, and glycerin are suspended as well and ‘hold on to’ the methanol. While washing, water is passed through the biodiesel. The methanol is attracted to the water and the biodiesel repels it. More traditional biodiesel washing method widely used in biodiesel production and additional contaminated substances to remove the remaining chemicals is used for.
