  • BIODIESEL PURIFICATION METHOD
    Publication number: 20110209981
    Abstract: The present invention concerns a process for purification of biodiesel obtained from castor seed oil for the purpose of promoting the efficient separation of the glycerine fraction formed during the transesterification reaction of a mixture of long-chain triglycerides derived from the oil in the presence of ethanol and an alkaline catalyst. The invention concerns the application of the method of electrostatic separation to biodiesel from castor oil in order to separate the glycerine from the stable emulsion then formed, in relatively short spaces of time.
