In BDF producing processes, separations of glycerol, methanol and catalyst with gravity are insufficient, so crude BDF must be rinsed with a large amount of hot water. As a result of rinsing, tremendous amount of methanol dissolved in wastewaters. In a typical BDF production process, all the wastewater are distilled to recover methanol and water. To distill the wastewater, large amount of energy is needed. The energy consumption is estimated as 6.43% of higher heating value of BDF. This estimation indicates that reducing wastewater amount can contribute to save energy consumption in BDF producing process. So, we tried to reduce wastewater amount by applying emusilication/demulsification technique.
