The diagram of the production of the Biodegradation process is presented schematically. This figure shows that in order to produce a high conversion rate of triglyceride, this process is carried out in two steps, initially in the first stage, 90% of a solvent such as methanol or ethanol with a catalytic form such as sodium hydroxide or potassium hydroxide with the available seeds The first reactor is added and before the second step, the glycerol is eliminated to a great extent. Then add 10% of the remaining catalyst and solvent to the second reactor and wash it with hot water to make soap and foam and a small amount of glycerol Remove BIOS and get BIOS. Biodiesel separation methods.4 Due to the cost of raw materials and processes, cost…show more content…
It can be said that the wet process is used to remove impurities such as soap, catalysts, glycerol and the remaining biodiesel alcohol. While the main harmful factor for using water to clean biodiesel is to increase process costs and increase production time. In addition, the biodiesel phase separation from the water phase is hard and produces a large amount of sewage. For each biodiesel liter, about 11 liters of wastewater is produced. The biodiesel refinement alone accounts for about 10 to 11 percent of the total biodiesel production cost. Therefore, dry washing technology has been used for the use of ion exchange resins and the use of special powders to eliminate biodiesel contamination. This technology needs to be integrated into the business environment for the purification of…show more content…
The use of membrane methods has many advantages that it can be considered as an appropriate replacement for wet and dry washing methods to eliminate the defects of these methods. When the raw material contains a large amount of water and free fatty acids, it can easily interfere with the process of exchange of the ester and form the soap and, in that direction, it is effective in reducing the biodiesel purification process by lowering the percentage of alkyl ester. Therefore, the European Standard (EN 14214) and the American Test Materials Standard (ASTM D6751) must be considered for the purity of the biodiesel required [4]. Table 1The values for these two standards are given. 5. Biodiesel isolation vote methods .1 Wet biodiesel washing5 In this process, add some water to the raw biodiesel, and peel off slowly to form the emulsion. This process continues until the wash water is completely colored, indicating complete removal of the pollutants. As a result, pure biodegradation is achieved after these steps. The disadvantages of this approach include the high consumption of water and the high cost of it. 5.2 Biodiesel drying This type of technology is usually done using silicates, active fiber, active clay, activated carbon, cellulose. These materials are essentially acidic, absorbent sites that are good for
