How To Make Bio Diesel?
Although it is barely a new concept, the idea of making a bio diesel has gained much popularity these days. Actually, the idea was conceived with the development of the first compression-ignition engine, which used peanut oil. This is an important point to remember when one wants to learn how to make bio diesel.
Bio diesel therefore refers to the non-petroleum-based fuel made from animal or vegetable fat. This fuel is usually mixed with ordinary diesel or used alone with an ordinary diesel engine. As such it is a viable alternative fuel source especially with the increase in fossil fuel prices.
Making bio diesel is not a very difficult process. This makes it possible to learn the skill from different sources. There is a wide selection of materials that can be used in producing this product. These include feedstock and oils such as soybean or rapeseed oil. Bio diesel can also be extracted from vegetable oils especially from hotels. Animal fats such as chicken fat lard and tallow. In some cases, algae is also used but not for commercial production.
The first step when you want to learn the art of making bio diesel is identifying the source oil. This is because the process varies slightly with different materials. Some of the materials will also necessitate the acquisition of special equipment like a bio diesel processor. Some of the cases however do not require such equipment like in the case of making the diesel from used cooking oil with methanol and sodium hydroxide. This method however, does not produce large amounts.
After establishing the oil source, the next step is testing it. This is necessary since the quality of your final product is usually determined by the ingredients. The two main factors that determine the quality of bio diesel you get are how acidic the source oil is and how wet it is.
The best oil sources, which will make the process easier, are those with relatively low water and acidic content. This necessitates the need to learn how to test the oil using different methods such as heating or using a water testing kit. Acidity is tested by adding the oil to a pH neutral alcohol, a process called titration.
Filtration is another major step in making bio diesel. This is vital especially when one is using vegetable oil from restaurants as it helps remove food particles or any other contaminant. Filtration is normally done using drums, which are highly effective. For better filtration, it is good to understand micron rating. A filter with a smaller rating has smaller holes.
Before you can embark of full production of bio diesel a test batch is very important. You should therefore learn how to make this using items obtained from the local grocery stores. You will also need to obtain the actual production equipment. Some of the equipments needed include oil collection containers, oil transfer and filtering capability, a bio diesel processor and bio diesel washing vessel. You also require storage containers, transfer pumps and a titration kit.
Normally the projected production capacity is one of the main factors determining the equipment to be purchased. With all this information in mind, it will be possible to learn how to make bio diesel.
