Plant For The Production Of Biodiesel

Model No. DL BIO-10

Biodiesel is a liquid biofuel obtained by chemical processes from vegetable oils or animal fats and it is an alcohol that can be used in diesel engines, alone or blended with diesel oil.
ASTM International (originally known as the American Society for Testing and Materials) defines biodiesel as a mixture of long-chain mono alkyl esters from fatty acids obtained from renewable resources, to be used in diesel engines.
The chemical reaction that converts vegetable oil or animal fat to biodiesel is called transesterification. This is a long name for a simple process of combining a chemical compound called an ester and alcohol to make another ester and another alcohol.
Oils and fats are included in the ester family.
When they react with methanol or ethanol, they make methyl or ethyl esters and a new alcohol called glycerol or, more commonly, glycerin.

Technical Specifications
Structure:
– The plant is mounted on a structure made of 40x40x2 square tubes of stainless steel AISI 304.
– The total dimensions of the plant are 1100 mm. long and 650 mm. deep.
Methoxide tank:
– A 5-litre capacity tank made of plastic material in which the methoxide is stored.
Pre-treatment tank:
– The oil to be treated is stored in a stainless steel tank of 200 mm. diameter and 350 mm. height for a volume of about 10 liters.
– The tank is provided with flanged caps for easy dismantling and cleaning. It is used to perform the pretreatment of the oil, by means of a stirrer, a heating resistor and a temperature sensor with digital controller to maintain the desired value.
Reactor:
– The oil is transferred to the reactor by a metering pump with the regulation of the flow, which is subsequently used to perform
the recirculation in the reactor while the reaction takes place.
– This reactor is a stainless steel tank of 200 mm. diameter and 350 mm. height for a volume of about 10 liters. This tank is also provided with flanged caps for easy dismantling and cleaning
Pump:
– A peristaltic pump with an adjustable flow rate that, by means of a valve system, is responsible for: the transfer of the oil from the tank to the reactor, the metering of the methoxide, and the recirculation.
– By means of the same metering pump the methoxide, comes from a tank of 5 liters. made of plastic material, is added to the reactor.
Electric Box:
– The inside of the box has all the necessary elements for the activation of the electrical components, as well as the necessary protections against electrical failures, like overloads, short circuits, or currents that derive to earth, according to the electro-technical standard in force for the protection of people and equipment.
– The activation switches of the various elements (Resistances, Stirrer, Pump) are located on the front.
– There is also a general on-off switch and an emergency stop button.
