Equipment and process for producing biodiesel cracking fat with the help of ultrasound and hydrogen peroxide, where preliminary filtered fat is placed at least into one tank (1) and its temperature is raised with the help of heat exchanger (2) up to 35 - 50 C° to reduce the viscosity. Fat is circulated in the tank (1) through the ultrasonic device (3), which is mixing fat in micro scale. 'When the appropriate viscosity is reached, the fat will be transported irtfo the next ultrasonic device (4) where the cracking is continued using ultrasound and hydrogen peroxide. The frequency of ultrasonic sound in all devices is 15 - 55 kHz. After that the fat is transported into at least one tank (5), where aqueous and fat phases will be separated by settling. Temperature of the fat will be kept still at 35 - 50 C° using heat exchanger (6) and to stimulate the process the grease will be circulated in the tank (5) through the ultrasonic device (7). Produced biodiesel will be filtered. Resulting water with its ingredients (possibly table salt for example) will be handled in an appropriate way.

Description

Equipment and process for producing biodiesel using ultrasound and hydrogen peroxide
FIELD OF THE INVENTION
The present invention relates to equipment and process for producing biodiesel, where ultrasound is used to destruct heated fat and hydrogen peroxide is used as an oxidant.
BACKGROUND INFORMATION
Biodiesel is commonly produced by using esterification process, where fats (triglycerides) react with alcohol (ethanol or methanol) forming long chained fatty esters. As a catalyst, sodium or potassium hydroxide is used in the process. While using ethanol, ethyl esters will be formed, while using methanol, methyl esters will be formed, etc. As a side product raw glycerol will be formed, which has to be removed from biodiesel. Additionally there are small amounts of soap or sodium and potassium esters of fatty acids present. There will be formed at least 10 % of glycerol, but it can be even half of the amount of the final product. This is unwanted as a product. Refined glycerol can be used for example in cosmetic industry as a raw material, but raw glycerol has no economical value.
Common esterification reaction is described by the following formula:
o CH2O - C - R ?H20H
CH-O -I- R + CH OH S CH-OH
I O + CH3OH QH ^ 3CH3O- C-R + I
CH2O -C - R Catalyst Esters CH20H
Alcohol Glycerol
Glyceiide
Glycerol and biodiesel will be separated from each other by settling or centrifugalizing. Alcohol which has not been reacting will be separated from the end product by evaporating or distilling. Biodiesel can be washed with water to remove the remains of soap and alcohol. Such process is described for example in publication US 2005011112.
Publication US 6440057 describes an equipment and a process for producing biodiesel, which differs from above mentioned, by influencing chemical reactions with physical means, using for example pressure and ultrasound. A disadvantage of both of these solutions is that a significant amount of raw material will be turned into unwanted side products like glycerol or soap; in both methods alcohol and catalyst are needed.
SUMMARY OF THE INVENTION
Purpose of this invention is to provide a simple, reliable and easy-to-use as well as more efficient than known solutions and more environmentally friendly (as no glycerol will be formed) equipment and related to that process to produce biodiesel, where animal or/and vegetable fat consisting raw material (below the term "fat" is used). The whole process takes place in 35 - 50 0C, which is considerably lower than in known processes, where the temperature is usually about 70 0C. Fat is cracked in several tanks using ultrasound and hydrogen peroxide. Ultrasound will mix fat in micro scale. Frequency of the used ultrasound is 15 — 55 kHz. Fat is also circulated from the bottom of the tank back to the top, which will provide additional mixing. Hydrogen peroxide is added into the equipment to act as an oxidizer. Amount of the added hydrogen peroxide depends on its concentration and is 1 - 10 % of the amount of fat
Hydrogen peroxide gives away oxygen atom so that water still exists in tanks. Most of the table salt fat possibly consists, extracts into the water phase, which is good from the point of view to the burning of biodiesel, as chlorines corrode materials in connection with the burning. Water and fat phases will be separated from each other by evaporating. Water sinks to the bottom of conical shaped tank. Biodiesel needs no more purification except the removal of water and filtering.
BRIEF DESCRIPTION OF THE DRAWINGS
For better understanding of the invention and to describe it: FIG 1 shows the equipment for producing biodiesel; FIG 2 shows the process for producing biodiesel.
DETAILED DESCRIPTION OF THE INVENTION
FIG 1 shows schematically equipment for producing biodiesel which consists at least one unit which consists at least one tank 1 , at least one heat exchanger 2 and at least one ultrasound device 3. Tank 1 is for mixing prefiltrated fat (filter is not shown) and the heat will be raised by the help of a heat exchanger to 35 — 50 0C to lower its viscosity. Also to lower the viscosity and to improve cracking the fat is circulated from at least one tank 1 through at least one ultrasound device 3, which mixes fat in micro scale. At least one mixing tank 1 and at least one ultrasound device 3 are connected to each other in series or in parallel, or the ultrasound device 3 is situated inside the said tank 1.
Ultrasound device 4 is used to continue cracking the fat before it enters the next unit
Ultrasound device 4 is connected to the oxidizer tank (not shown). Hydrogen peroxide is used as an oxidizer. Ultrasound cracks fat and oxidizer reacts with the resulting smaller compounds. Used frequency in all used ultrasound devices in the equipment is 15 - 55 kHz.
At least one unit is used to separate water and fat phases from each other, which unit consists at least from one tank 5, at least one heat exchanger 6, and at least one ultrasound device 7. In tank 5 the water and fat phases will be separated from each other by evaporating. Using the heat exchanger 6 the temperature of fat will still be kept at 35 - 50 0C, and to promote the process the fat is circulated from at least one tank 5 through at least one ultrasound device 7. At least one tank 5 and at least one ultrasound device 7 are connected to each other in series or in parallel or the ultrasound device 7 is situated inside the said tank 5. Produced biodiesel will be filtrated (filter is not shown). Separated water with solutions will be handled duly.
Subject of the invention is also a process for producing biodiesel as shown in FIG 2, where fat is cracked with the help of ultrasound using hydrogen peroxide as an oxidizer. In a process at least one unit is used, which consists of at least one tank 1, at least one heat exchanger 2 and at least one ultrasound device 3. Prefiltrated fat (filter is not shown) will be added into tank 1, where it will be mixed and the heat will be raised to 35 — 50 °C to lower its viscosity. Also to lower its viscosity and to promote cracking of fat it will be circulated from tank 1 through ultrasound device 3, which are connected to each other hi series or in parallel or the ultrasound device 3 is situated inside the said tank 1. Fat is circulated from mixing tank 1 to the ultrasound device 3 and back. Used frequency in all used ultrasound devices in the equipment is 15 - 55 kHz.
When the desired viscosity is reached, the fat will be removed into the next ultrasound device 4, where the cracking process will continue.
After that the fat will be removed into a unit, which consists of at least one tank 5, at least one heat exchanger 6, and at least one ultrasound device 7. In tank 5 the water and fat phases will be separated from each other by evaporating. Temperature of the fat will still kept at 35 - 50 0C, and fat will be continuously mixed to promote the process and to prevent the produced biodiesel to sediment from tank 5 through ultrasound device 7, which are connected to each other in series or in parallel or the ultrasound device 7 is situated inside the said tank 5. Produced biodiesel will be filtrated (filter is not shown). Separated water with solutions will be handled duly.
A person skilled in the art understands, that one can make changes to above-described embodiment without violating scope of the invention. For example there may be added valves, pumps, filters or monitoring elements and different equipment to control the biodiesel producing process.
