Bio-Diesel / Veg Fuel

Puric Filtration of cold pressed vegetable oil
We have designed a special Series Filtration Systems with our Past experience,we can now offer filtration solutions for cold pressed vegetable oil. Cold pressed vegetable oil is used in two main applications: as fuel oil and for food purposes. This oil can also be converted into biodiesel (rapeseed methyl ester, RME, or vegetable methyl ester, PME). Rape seed is the main raw material for the fuel oil. For food purposes also other vegetable oils are used.

Puric Procedure to filter cold pressed vegetable oil.
Cold pressed vegetable oil (from pressing the oil seed in the press) is normally treated with Seriese filtration steps after each other. Oil for fuel applications has to reach the required quality, according to the future set Quality standard E DIN 51605 for rape seed oil as fuel. The three step Abhishekfilters filtration system can reach the required fuel oil quality of less than 20 mg solids / kg oil very esiely.

Abhishek Filtertechnik can supply the individual components as well as the complete filtration system. Complete Pre Fabricated Unit on Skid are available in varying sizes for complete systems. The filtration units can be supplied either manually operated or fully automated. For installation and commissioning Abhishek Filters can offer a complete Cooperation.

We have supplied few Plant in U.K. for cold pressed vegetable oil are successfully in operations.

The higher the value of the viscosity, the thicker the plant oil becomes. A high viscosity of the oil can cause low pumping speed and harder filtering possibility. That's why it will be favourable for the filtering process to have a rape seed oil temperature between 20 and 35 C, depending on the filtering technology.

Biodiesel
Biodiesel is a fuel that has much the same characteristics as normal diesel oil, but as opposed to diesel it is not derived from petroleum but from vegetable oils or animal fat. Generally, vegetable oils are used such as sunflower oil, soy oil, rape oil or palm oil. Used oils may be used likewise very well indeed. To produce biodiesel from these oils, they are subjected to a chemical reaction, which is called transesterification. It is a chemical reaction that makes the glycerol present in the oil to be substituted by methanol, using a lye as a catalyst. Its result is a methyl ester. One of its examples is rape methyl ester (RME). A residue forms due to transesterification, called glycerine. This can be applied in various ways, one can think of such things as making soap.

Why?
Biodiesel's plus-points are obvious: It is biodegradable, it decreases soot-emission with 50%, it decreases emission of hydrocarbons and it is CO 2 -neutral. In addition to these environmental plus-points, it is safe indeed (its flashpoint is 170C ) and it is easy to mix with fossil diesel.

Where?In several European countries, including Austria, Italy, Spain, Frace and Germany biodiesel is seriously applied, with France and Germany as absolute leaders. Over 150,000 cars run on biodiesel in Germany, for instance, and scattered over the country there are well over 1,200 service stations with a biodiesel pump. The reason of the biodiesel success in Germany is the fact that no excise is levied on biodiesel, which makes its price an average of 4-8 cents below that of normal diesel. In the Netherlands we are hopelessly trailing behind in the use of biodiesel. One of its reasons is the uncompromising attitude of the Dutch government towards biodiesel. An example is the fact that it does not intend to lift excises on biodiesel. Eventually they will come round in the Netherlands, mainly due to pressure from Europe and European legislation with regard to biofuels.

What is transesterification?

The process of converting vegetable oil into biodiesel fuel is called transesterification, and is fortunately much less complex than it sounds.
Transesterification refers to a reaction between an ester of one alcohol and a second alcohol to form an ester of the second alcohol and an alcohol from the original ester, as that of methyl acetate and ethyl alcohol to form ethyl acetate and methyl alcohol  . Chemically, transesterification means taking a triglyceride molecule or a complex fatty acid, neutralizing the free fatty acids, removing the glycerin and creating an alcohol ester. This is accomplished by mixing methanol with sodium hydroxide to make sodium methoxider . This liquid is then mixed into vegetable oil. The entire mixture then settles. Glycerin is left on the bottom and methyl esters, or biodiesel, is left on top. The glycerin can be used to make soap (or any one of 1600 other products) and the methyl esters is washed and filtered.
