Biodiesel Purification – Final Part 5
Overview In this fifth and final installation on biodiesel production we will cover biodiesel purification. Biodiesel Purification by Distillation There are two distinct process for biodiesel purification. One is removal of methanol by distillation and the other is removal of glycerin and the sodium methylate catalyst by ion exchange. The crude biodiesel product is preheated … [Read more...]
Transesterification – Biodiesel Part 4
Overview The transesterification unit is designed to produce ASTM grade biodiesel by reacting low FFA oil or preesterified oils with excess methanol in the presence of a sodium methylate catalyst. Evaporator An oil drying system (Evaporator not shown) removes water and methanol after the esterification unit but prior to the transesterification system. The recovered … [Read more...]
