Can start bio-diesel production unit as a small scale basis
at any place. You need to select a location where the main
raw material Jatropha oil is easily available.
Basically, the term biofuel is used to define fuels that are
obtainable from plants or animals. Jatropha Curcus is a large
3 to 4 Meter high shrub, It kernel yields 55 percent by weight
of oil, which is 35 percent of seed weight.
The oil is generally called Circus oil. On Etherification,
the oil becomes Bio-Diesel. You can blend it with high-speed
Diesel from 20 to 80 percent by volume.
Various types of engines are coming today to run on a wide
variety of fuels. Including premium motor spirit (petrol),
gas or diesel as their primary fuel, with all these types
of engines, the diesel engine is the one most suitable to
run on bio fuel.
Bio fuels are very similar to diesel fuel in composition;
therefore, there is no need for engine modification to run
on bio fuels. Diesel engine burns less fuel producing the
same amount of work when compared to a petrol engine.
Bio-diesel is a carbon-neutral source of fuel and is
increasingly becoming popular.
License & Permissions: Register your firm first and must
obtain Trade License from local Municipal Authority. Apart
from these, you need to apply for following permissions:
Factory Licenses: For setting up of any Factory, one needs
to take an approval from the District factory Inspectorate.
Explosive License: For storage of Methanol, one has to obtain
an Explosive License from the Directorate of Explosive.
Pollution Control Board Clearance: You must need to have the
clearance from Pollution Control Board.
Bio-Diesel Production Unit Setup & Process:
You can establish bio-diesel production unit by two ways. One
is producing bio-diesel from jatropha oil. Another one is
producing jatropha oil and then biodiesel from that.
For the first option, the main raw material is jatropha oil
and for the second one, the main raw material is jatropha
seed. Here we will discuss the process and equipment for
bio-diesel production from jatropha oil.
Machinery used in the production of the biodiesel are as
follows: thermometer, retort stand, pipette, measuring cylinder,
magnetic stirrer, separating funnel, oven, water bath, hydrometer,
conical flask, digital weighing balance, stopwatch, hot plate,
distilled water, methanol, and jatropha oil.
Manufacturing Process: Bio-diesel production process using oil
in methanol in a shaking incubator at 250 rpm and 45° C for
1. First, dissolve the lye into the methanol. Shake or swirl
until all the lye has dissolved.
2. This may take 10 minutes. It is normal that temperature
rises. This mixture is called sodium methoxide. Make sure
the J Oil is in a vessel large enough (at least 150% of its
volume), preferably with a valve at the bottom, and heat it
to about 60 °C, then stop heating. Then add the methoxide
mixture. Make sure that you mix it well for at least 10
minutes. Leave the vessel and let the different constituents
separate by sedimentation.
3. The glycerin will settle out at the bottom. After 8 to 24
hours the sedimentation is complete and the glycerine can be
4. What remains is raw biodiesel. If the reaction went well
and the biodiesel is clear, you can use it straight, although
its quality may be inferior because of impurities. Water washing
will remove most of these impurities.
Commonly used methods for bio-diesel production are batch
and continuous processes. Smaller capacity plants and variable
feedstock quality warrant use of batch systems. Continuous
systems generally lead the operation on a 24×7 basis, requiring
larger capacities to justify larger staffing needs and also
requiring uniform feedstock quality.
This standard prescribes the requirements and methods of sampling
and tests for bio-diesel suitable for fuel in diesel engines.
