Ultrasonics for the biodiesel production

Reading Time: < 1 minutes
One can’t emphasize enough the importance of the continuous production of biofuel. It is made from biological products and performs similarly to petrodiesel, it is known as biodiesel. Any amount of biofuel used in place of fossil fuel helps cut down on greenhouse gas emissions.

One can only accurately assess the effects of transitioning from fossil fuels to biofuels when carbon reduction is a top concern. Governments all over the world are favoring biodiesel leading to an acceleration of the requirement for it. Which naturally leads to an increase in the production of biodiesel.

What are the current methods of producing biodiesel?

Transesterification Method

The glycerin is extracted from the fat or vegetable oil to create biodiesel through a chemical process called transesterification. The chemical process of transesterification turns vegetable oils into an alternative fuel decreasing the viscosity. It has high combustion efficiency, low emulsion, and all renewable properties are present. The two byproducts of the procedure are methyl esters and glycerin. Biodiesel is known chemically as methyl esters, and glycerin is a common ingredient in many goods.

Pyrolysis Method

Oils undergo thermal degradation in the presence of air or nitrogen gas during pyrolysis method. Fuel produced by pyrolysis can be made more affordable than fuel produced through transesterification as it can be done by using low-quality raw materials.

Dilution Process

Dilution is the process of thinning waste and vegetable oils by combining them in a certain ratio with a solvent or diesel fuel. The mixing of lubricants and diesel fuel is the most typical of these procedures. Resulting in decrease in viscosity and reduces biodiesel fuel utilization.

Ultrasonics for the production of biodiesel

For the generation, numerous studies on hydrodynamic cavitation, ultrasonic cavitation, and mechanical stirring technique were conducted. The results favored that ultrasonic irradiation conditions are efficient, time-saving, and economically functional to produce biodiesel fuel.

The integrated transducer acoustic rod horn emits ultrasonic radiation that triggers the reaction. Cavities are produced by irradiating immiscible liquid (oil and alcohol are not miscible with each other) with power ultrasonic at a high enough energy level. As a result, microfine bubbles are formed, and these bubbles collapse at different locations throughout the reactor, disrupting the phase boundary between the two immiscible liquids and leading to the emulsification of the mixture.

Using ultrasound as a physical principle to produce biodiesel during research and experiments, has given promising outcomes so far.

Reaction time, temperature, and energy input can be significantly reduced when producing biodiesel using an ultrasonic sonicator. The process can be carried out continuously utilising such reactors as opposed to time-consuming batch processing. Ultrasonic devices on an industrial scale enable the daily processing of huge amount of biodiesel.

Ralsonics has been in business with Ultrasonic technology for over 49 years. Ultrasonic biodiesel processing using Ralsonics's Sonicator helps provide a significant improvement in yield. Ralsonics provides a full array of ultrasonic cleaners and sonicators. With the company's ability to design and build its own equipment, the products can be customized to meet specific requirements.
