We produce this system turnkey.
We manufacture these facilities in turn-key delivery. Our company produces biodiesel plants as turn key.
Apart from the normally produced reactor batch system, THIN FILM integration enables us to manufacture in compliance with EMRA norms to meet very high quality and specifications.
The desired batch can not be obtained in the normal batch reactor system, which causes damage to the engines of the vehicle due to the lack of biodiesel quality, but due to THIN FILM distillation, the methyl ester is separated from undesirable substances and bio diesel of high quality is obtained.
As ATILIM MACHINERY we manufacture turnkey biodiesel plants.
Biodiesel is an alternative fuel, equivalent to conventional fossil species.
Biodiesel can be produced from animal and vegetable oils, candle oils and household waste oils.
The process of converting these oils into biodiesel is called transesterification.
The most important useful sources of fat are oilseed products such as rapeseed, palm and soy. Among them, rapeseed is the most used product for biodiesel production.
Most biodiesel produced today is made from waste vegetable oil from industrial food producers and large restaurants.
Since the cost of crops produced for biodiesel production such as rapeseed oil is much higher than the cost of waste oils, the amount of biodiesel produced from waste oil is much higher.
Biodiesel is very important in terms of environmental pollution. Biodiesel is neutral carbon.
This means that there is no extra carbon output in the form of carbon dioxide after it has been used as fuel.
The reason for this effect is that the plants used in the production of biodiesel absorb carbon dioxide in the growth phase, as the amount of fuel that is attacked in the combustion stage.
However, it should not be forgotten that the fertilizers used in the growing stage of the produced plants also released significant amounts of carbon dioxide.
It would also be inappropriate to limit the sources of pollution associated with biodiesel production to fertilizers alone.
Other sources of pollution encountered during biodiesel production include: Esterification, oil solvent extraction, refining, drying and transport processes.
All these processes require a certain amount of energy input in the form of electricity or fuel, and both eventually release greenhouse gases.
However, the rapid degradation of the soil and the absence of any toxic effects make biodiesel waste much less risky than the wastes of fossil fuels, and these properties are considered to be one of the most important enhancements.
Another important detail is that the glare point is higher than fossil fuels. This feature also reduces the risk of explosion, especially during an accident.
Biodiesel production: As we have mentioned above, biodiesel can be produced from vegetable oils, animal oils, candle oils and waste oils.
Today, there are three basic ways to produce biodiesel from oils. These; Transesterification of the oil by base catalysis, transesterification of the oil by direct acid catalysis, and conversion of the oil into fatty acids.
Nearly all biodiesel is produced by base catalyzed transesterification, which is the most economical method and requires only low temperatures and pressures and can achieve approximately 98% efficiency. For this reason, we will point to this method in this article.
Transesterification process is the reaction of triglyceride with alcohol to form ester and glycerol.
The basic structure of a triglyceride is composed of glycerine molecules containing three long chain fatty acids.
The nature of the fat is determined by the structure of the fat acid bound to the glyceride found in its structure.
This structure of fatty acids also characterizes biodiesel. During the esterification process, triglycerides and alcohol molecules react in the presence of a catalyst.
The reaction of fatty acids with alcohol results in mono alkyl ester or biodiesel and crude glycerol.
The alcohol selected for the reaction is usually methanol or ethanol. As a catalyst, potassium hydroxide, which is usually a strong base, sodium hydroxide, is used.
While potassium hydroxide is more useful for ethyl esters during biodiesel production, both can be used for methyl esters. The most common transesterification process is the reaction of rapeseed oil as RME with methanol. There is a reversible reaction between oil and alcohol.
For this reason, it is necessary to put alcohol in excess amount of alcohol in order to increase the efficiency.
In order to obtain a successful transesterification reaction, it is necessary to separate the glycerol and ester layers after the reaction is complete.
Once the heavier and lowered glycerol is separated from the medium, it can be purified purposely for use in different industries such as pharmaceuticals and cosmetics.
Some vegetable oils can also be used directly instead of fossil The risk of causing serious motor problems is very high. Some vegetable oils with very high viscosity cause low atomization of the fuel, incomplete combustion stage, accumulation of injectors in the soot, and fuel in the machine oil.
The transesterification process helps to prevent these problems. The benefits of the transesterification process in the foliage can be listed as follows: Decrease in viscosity? Removal of glycerides completely? Decrease of boiling point ?? Decrease of flash point ?? Increasing the degree of fluidity Mixture of alcohol and catalyst Sodium hydroxide (caustic) and potassium hydroxide (potassium) are used as catalysts.
These catalysts dissolve in the alcohol with the aid of a standard mixer.
The alcohol / catalyst mixture is then transferred to closed reaction vessels and oil is added to the reaction.
This system is completely closed to avoid any alcohol loss during the reaction.
The reaction mixture is maintained at a temperature just above the boiling point of the alcohol so that the reaction time is rapid.
The recommended reaction time is between 1 and 8 hours and it is recommended that the reaction be carried out at room temperature for some systems.
In order to achieve complete conversion, the alcohol is added to the excess.
The amount of free fatty acids and water in the oil to be added to the reaction should be well observed.
If the amount of fatty acid or water is too high, problems such as soap formation and difficulty in removing the glycerin from the environment can occur.
After completion of the reconditioning, two main products are formed: glycerin and biodiesel.
Each contains the excess of the methanol used in the reaction, so neutralization can be applied at this stage if desired.
Since the glycerin phase is much more dense than the biodiesel phase, it can be separated gravimetrically by a simple process.
In some cases, centrifugation can be used to facilitate separation.
Alcohol Removal After separation of glycerine and biodiesel phases, the excess alcohol found in both phases can be separated by distillation or evaporation.
In some systems alcohol, glycerin and biodiesel phases can be neutralized by removing them before separation. In both cases, the alcohol is recovered and can be reused.
Glycerine Neutralization Glycerine, a side product of the preparation, contains catalyst and soap which are not used in the reaction.
For this reason, glycerin can be neutralized with acid and used for different purposes. In some cases, salt is formed at this stage and this salt can also be used as fertilizer.
Often this salt remains in glycerin. In order to obtain crude glycerin, the obtained glycerin should be removed from alcohol and water to reach 80-88% purity.
By applying some special procedures, the purity of the resulting glycerin can be brought to 99%. The biodiesel removed from the Glycerin of the Methyl Ester is sometimes washed with hot water to remove the catalyst or soap, which is then dried and ready for consumption.
In some processes this process may not be needed. This step is the last part of the production process and results in a greenish amber-colored and viscous oil-diesel-like liquid. Some systems may also be subjected to a final distillation step to remove the biodiesel-containing coloring matter.
After this step, colorless biodiesel is obtained. Quality of the product Before the commercial product is delivered, the product is analyzed with some special equipment to test whether it meets the required specifications.
To make sure that biodiesel is produced without problems, look at the parameters: ?? Do not drink glycerin ?? Does not contain catalyst ?? Do not drink alcohol ?? Contains free fatty acidWhite: //[ URL HIDDEN ]
