PLANT FOR THE PRODUCTION OF BIODIESEL
DL BIO-10
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 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 the 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 a 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 an 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.
Pump
A peristaltic pump with 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, coming 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 electrotechnical standard in force for the protection of
people and equipment.
The oil is transferred to the reactor by a metering pump with 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
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.
The power supply is single-phase with neutral and earthing.

Biodiesel production
The process to make biodiesel involves a chemical reaction. This means that
the biodiesel industry is a chemical industry. Those involved in making
biodiesel must have a good understanding of the underlying chemistry to ensure
they are making quality fuel in a safe manner. Biodiesel is an alternative
fuel for diesel engines. It is produced by chemically reacting a vegetable oil
or animal fat with an alcohol such as methanol or ethanol.
The vegetable oils and animal fats used to make biodiesel can come from
virtually any source. All of these products consist of chemicals called
triglycerides; so, biodiesel can be made from soybean oil, canola oil, beef
tallow, and pork lard, and even from such exotic oils as walnut oil or avocado
oil.
Even used cooking oil or waste oil can be used to make biodiesel.
However, these oils present special challenges for the biodiesel production
because they contain contaminants such as water, meat scraps, and breading
that must be filtered out before the oil is converted to biodiesel. Methanol
is the most common alcohol used for making biodiesel.
Description of the process
Oil and glycerin are inserted In the pretreatment tank and heated to 50 °C,
continuously stirring. The mixture is then settled and decanted to remove any
impurities from the oil.
The oil is then heated to 70-90 °C until the bubbles disappear. Then, by means
of the pump, the oil is sent to the reactor and heated, while keeping the
temperature between 50 and 55 °C. Methanol and sodium are mixed in the
methoxide tank. The recirculation of the oil starts with the pump and is
continued, while 75% of prepared methoxide is added in 1.5 hours. Let stand
and decant.
The recirculation of the oil starts again, while 20% of the methoxide is added
in 1.5 hours. Let stand and decant. The recirculation of the oil starts again,
while the remaining 5% of the methoxide is added in 1.5 hours. Let stand and
decant.
In this way biodiesel is obtained. The next step is to wash and purify it.
