| Bio-Diesel Introduction Continued
By morning, there should be a clear separation between the crude Bio-Diesel fuel on top and the heavier and darker Glycerine layer below. The ratio, depends on the quality of the oil used and should be approx. 80% : 20%. The Glycerine layer is then drained off and used in compost production or stored for waste collection.
The crude Bio-Diesel fuel is then ‘washed’ with water. This may appear a big mistake, adding water to a fuel, but is part of a simple physics operation. As the water is added to the Bio-Diesel it falls though it and removes most of the trapped impurities.
This initial washing process usually takes 6 hrs and uses approx 20% by volume water. After settling for 18 hrs, the water should appear ‘milky’. This in fact is a very good sign as it indicates the amount of impurities that have been washed out of the Bio-Fuel. The whole process is repeated at least two more times, by which time the fuel on top is clear and sparkles and the water layer is virtually clear as well. A further 3 days of settling ensures that all the impurities have ‘fallen out’ of the Bio-Fuel.
The Bio-Fuels generator (processor) performs the mixing stage of Bio-Diesel production. As stated, it contains a heater element, to assist the chemical reaction and a paddle mixer. It is a relatively simple device but effective and robust in its construction.
The settling tank is a simple I.B.C container and is readily available second hand for £50-£100. The ‘Washing Machine’ again is a simple but robust device. It incorporates a constant ratio pump, a sprinkler system and a heater again based on an I.B.C. container. It allows for the waste water to be disposed of quickly.
