Biodiesel

A mix of vegetal oil and anhydrous alcohol capable of reducing the presence of polluting gases on the environment, generate funds and bring economic development. This is the biodiesel scenery in Brazil, all the time more competitive against the inevitable future scarcity of fossil fuels and the systematic actions of the global warming fight. For those who desire to take advantage of the moment and invest in this promising market, Ecirtec offers several equipment and develops projects for the production of biodiesel from several raw materials, always according to the ANP (NATIONAL PETROL AGENCY) specifications. Biodiesel Biodiesel production is done from oil or available fat. If we have available a certain oleaginous seed, the following processes:: 1. OIL EXTRACTION:

the oleaginous seed will be properly prepared and pressed for oil extraction. In large scale the extraction is done by solvent. The cake (solid part) resultant of the pressing will be treated and can be utilized as fertilizer, animal food and even human food. The cake application will be according the quality and raw material type and the operational conditions adopted in the extraction. The obtained oil follows to the next step; 2. OIL TREATING:

depending on the oil quality obtained in the previous step (or from third parts and/or recycling), we’ll have one or more of the following processes: filtration, degumming, neutralization, draining and winterization. To this point we’ll have clean oil, without gums, without acidity, without waxes and dry to be sent to the biodiesel production section through transesterification. 3. TRANSESTERIFICATION:

in this process, the oil is mixed with alcohol (ethanol or methanol) in a tank with mechanical agitation, in the presence of a catalyzer. The reaction originates biodiesel and glycerin, substance present in 20% of vegetal oil. 4. SEPARATION:

with specific equipment (decanters or centrifuges) the glycerin is separated from biodiesel. At this point we’ll have biodiesel and glycerin still with alcohol presence. Through evaporators, condensers, washing and draining system biodiesel will be purified. Glycerin then without alcohol can be sold gross or go through a specific purifying and be utilized in the industry.
