Bio Diesel

Bio-Diesel Production:

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 4 hours.

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 drained off.

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.
