Methylester and Glycerin Production

DSEC's commitment on the construction of Biodiesel plants is based on a very specialized technical knowledge of the Biofuels production processes; in this article you will find a more detailed understanding about the process of Methylester and Glycerin Production. Transesterification The transesterification reaction is accomplished in continuous, using reactors in series operating under mild conditions. The raw material is dried in flash chamber and then is continuously fed to the first reaction loop. Catalyst is continuously dosed. The Methanol is fed to the reaction unit in a proper excess. The separate glycerin is rich in soap and is directly sent to the glycerin treatment. The light phase outgoing from the head of the first reaction loop is transferred to the second reaction loop after the addition of fresh methanol and catalyst. The light phase coming from the top of the second reactor is transferred to the third reactor with addition of methanol and catalyst. The third transesterification reactor is a stirred vessel. The glycerin separated at the bottom of the second separator, relatively rich in methanol and catalyst, is recycled to the transesterification unit. The reaction mixture leaving from the third reactor containing the product (Methylester), the excess of methanol and the glycerin (reaction by-product) and a limited amount of soaps is sent to the Methylester purification section.
