Biodiesel is a proven alternative to petroleum diesel fuel. Once produced, biodiesel contains several impurities such as soap and glycerin. The free fatty acids in the oil react with the sodium or potassium catalyst to form soaps. After the biodiesel and by product glycerin are separated, trace amounts of glycerin remain in the biodiesel. Soap and glycerin impurities in the biodiesel can lead to engine wear and fuel storage problems.
Traditionally, soap and glycerin are removed from the biodiesel by water washing. Water washing has several disadvantages such as producing large amounts of waste water that requires treatment and causing plant operational problems such as emulsion. Recently, several alternative “waterless” purification procedures have been used, such as ion exchange resins
