Bio Diesel Extraction Plant For every type of edible/non edible oil, we engineer and develop Bio-Diesel extraction Plant. In our range, we have different capacities of extraction plants ranging from 500 liter/day. In addition to this, transesterification plant comprises of reaction tank, catalyst mixture, washing system and settling tanks and methanol recovery. Bio-diesel is the product obtained by transesterification of any vegetable oil. Derived from renewable lipid sources, biodiesel is defined as the mono alkyl esters of long chain fatty acids. In the presence of a catalyst, the reaction of a vegetable oil or animal fat with methanol is carried out to yield glycerin and biodiesel.
