Transport consumes about 20% of the world's primary energy, mainly oil. This situation is unacceptable for countries that do not have their own oil reserves and want a stable economy and energy independence. Communities in many countries recognize that these problems continue to accompany the use of road transport and have long paid serious attention to the use of alternative fuels for vehicles, including biofuels, natural gas and hydrogen. However, in the current increase in the number of food industry facilities, it is necessary to deal with food products that have a negative impact on the environment (food fats). According to some data, the amount of garbage per day can range from a few kilograms to tens of tons.

Approximately 90% of diesel biofuels (DBs) are mainly derived from processed oils and raw materials, including fats and oils of animal or vegetable origin that are recyclable. Biofuel is a biologically harmless product. In contact with water, the wine does not harm aquatic flora and fauna. In water or soil, it undergoes almost complete biological decomposition. Combustion of diesel biofuels emits much less carbon dioxide (CO₂) than combustion of conventional fuels. Of course, there are drawbacks. First, biofuels have low frost resistance. Undiluted biofuel damages rubber hoses and gaskets. Biofuels have a certain shelf life. Due to increased maintenance costs, deposits can contaminate fuel equipment and filters during operation. Particular attention should be paid to the free glycerin that remains during production.

The article considers biofuel production technologies and methods of glycerin removal. The focus is on devices that allow you to remove glycerin mobile. As a result, a faucet was proposed in which a filter was installed to remove residual glycerin and a study of its operation using the FlowVision program was performed. The simulation model of operation of the mixer with reception of indicators of its work is executed.
