BIODIESEL PROCESSOR: MODERN BIODIESEL PRODUCTION TECHNOLOGIES
Unlike companies which manufacture biodiesel production equipment (biodiesel processor) based on outdated, tank technologies, which have been used for over a century, our company uses the high-frequency magnetic impulse cavitation principle, previously used in classified technologies, allowing us to achieve some significant advantages:
Low demands on the quality of the raw oil High-frequency magnetic impulse cavitation reactors work successfully and steadily with both raw and purified oil, and with all types of animal fats and fat mixtures with vegetable oils. This wide range of oils (sunflower oil, rapeseed oil, linseed oil, palm oil, mustard oil etc.) can be used for biodiesel fuel production with almost any acid number and it is also possible to use waste from livestock and poultry processing plants. The equipment does not need to be adjusted when the type of oil is changed.
“One pass” reaction procedure Unlike in outdated “tank” technologies, no re-etherification reaction is needed in magnetic impulse cavitation technology. This innovation means that the time taken to obtain biodiesel is reduced by a factor of 8-10.
Purifying sorbates, washing and drying are not required When using conventional technologies, it is not possible to obtain proper quality biodiesel fuel immediately. Therefore a process of impurity elimination, involving washing or purifying using sorbates, is needed. This requires additional equipment for primary biodiesel product washing (a mixture of water and alcohol is usually used for this purpose) and additional units for what is known as vacuum drying. When the cavitation biodiesel manufacture method is used there is no need for the finished product to be washed or dried, and this therefore eliminates waste water and sorbate utilization processes.
Minimal alcohol and catalyst quantity. No alcohol recovery process One of the main problems with “tank” technologies is the need to add, and consequently to recover, additional methanol to the reactor. This requires additional equipment and wastes electric power. In cavitation technology, the alcohol quantity used for the reaction conforms precisely to the stochiometric composition, i.e. the minimum volume. There is no need for a re-etherification reaction. The use of expensive and dangerous equipment for methanol recuperation is excluded from the process. Any inevitable alcohol losses during recovery are eliminated, which improves the environmental conditions and explosion-proof characteristics.
Minimum energy consumption Conventional biodiesel production methods are based on heating the oil to 67-70 °C. This involves significant electric power costs; in addition, the methanol recovery process (required when the reaction is carried out using conventional technologies), additional re-etherification and also vacuum dehydrating lead to considerable electric power consumption. The use of cavitation processing eliminates all the stages mentioned above, which means that 5-7 times less electric power is used.
Low-temperature reaction In high-frequency magnetic impulse cavitation, processing takes place in the reactor on molecular level. All components are exposed to magnetic-directed cavitation pulses. Fatty acid molecules are split using micro-explosions; this results in a decrease of viscosity, a cetane number increase, an improvement in the energetic parameters of the future fuel and a considerable acceleration and improvement of the etherification reaction quality. It must be noted that the reaction takes place at room temperature and there is no need to heat the oil.
- Minimal overall module dimensionsOur automatic modules take up 5-10 times less floor space than conventional equipment of a similar capacity.

Based on PULSAR-CT 805 the small-scale biodiesel plant can be organized with little effort. There are one input and one output on each side of the cavitation reactor, which makes it possible to connect two mixing tanks to the reactor at the same time. The operator can fill the second tank with the initial products, while in the first tank the mixture is being processed and further separation of the processed mixture to biodiesel and glycerol occurs (see the figure below).
Thus the operator can produce biodiesel in two tanks, one by one. In this mode the operator can produce up to 300 liters of biodiesel per 8-hour shift.
To increase the output of biodiesel four tanks can be connected simultaneously – by two on each side of the reactor.
BIODIESEL MADE OF ANIMAL FAT
Biodiesel derived from animal fat (waste from the processing of livestock) using the cavitation reactor PULSAR-CT. Animal fat was first liquefied (heated up to 60°C). Source components ratio: Animal fat – 5350 ml Methanol – 700 ml Catalyst (potassium methylate) – 50 g Processing time – 50 seconds Separation time (gravity method) – 20 minutes
BIODIESEL MADE OF CRUDE SUNFLOWER OIL
The picture shows the source oil (crude non-refined sunflower oil) and the result of source product treatment in the cavitation reactor PULSAR-CT. Test conditions: Crude sunflower oil – 7000 ml Methanol – 900 ml Catalyst (potassium methylate) – 65 g Processing time – 50 seconds Separation time (gravity method) – 20 minutes
