Biodiesel (fatty acid methyl esters or FAME) – biofuel that can
be used as an alternative to conventional diesel fuel. Biodiesel can be used either alone or in a mixture with a conventional diesel fuel. Produced in Europe biodiesel shall comply with EN 14214 standard. Biodiesel has many advantages compared to a conventional diesel fuel: cleaner emissions (CO, NOx), better combustion, purifying impact on engine, etc.

Biodiesel is typically produced by alcoholysis (particularly methanolysis) from vegetable or animal fats in the presence of a catalyst. Most processes are based on alkali catalysis with the use of potassium hydroxide to carry out so-called transesterification of fats.

Reaction time is usually several hours. In order to accelerate the reaction are used increase in temperature (heating) and pressure. More sophisticated approaches use special intensifiers of the process to accelerate the reaction. The principle of operation of such intensifiers based on various physical methods, such as cavitation, turbulence, ultrasound and other.

We have developed a technology of cavitational cascade biodiesel fuel production. It combines cavitation, turbulence, ultrasound and other physical processes to accelerate the catalytic process of biodiesel production. Intensifier of the process constitutes the core of the proposed technology.

Raw materials (vegetable oil) are mixed with methanol and the catalyst (potassium hydroxide) in a flow mixer with a proper proportion set by means of Automatic measurer.

Afterwards, the emulsion is fed into cascade cavitation reactor. Designed flow rate through the reactor ranges from 500 to 1000 liters per hour depending on the type of feedstock, operating temperature, and the customer’s wishes.

Then the emulsion enters the separation system (settling cone) for separating glycerol (usually runs for three hours at room temperature of 20°C). The number of settlers may be increased to ensure continuous production. Switching between the settlers carried out by means the pneumatic valves. Glycerol is drained via separate valve after separation.
