HVO | BIODIESEL

In general terms, the technological side of HVO production is hydrorefining of vegetable oils or oil and fat waste with their subsequent heating to high temperatures. As a result, they are separated into impurity fraction and odorless substance which is as close as possible to fossil fuels in its chemical structure. Low distillation range, increased cetane number and absence of aromatic substances significantly affects the stability of the composition and characteristics of this fuel, and consequently - the safety of its storage and use, the cheaper engine operation. Therefore, hydrogenated vegetable oil is positioned as an advanced, renewable and environmentally friendly synthetic alternative to conventional diesel fuel. Thus, use of 100% HVO reduces CO2 emissions into the atmosphere (the percentage varying depending on the type of feedstock), as well as significantly reducing the release into the environment of nitrogen oxides NOx, carbon monoxide CO (up to 65%) and particulate matter (up to 80%).

Blends of HVO with conventional diesel fuel also have a noticeable effect on the energy and emission parameters, allowing the maximum use of all the advantages of the first fuel and leveling the disadvantages of the second. Thus, unlike more fastidious biodiesel from FAME, hydrogenated vegetable oil can be mixed with conventional diesel fuel in any proportions, and 100% can be used to run diesel engines without any modification. There are no problems of special pumps at the gas station, special methods of transportation and storage, expensive engine maintenance, additional staff training and many others. That's why this biofuel is more and more often used by producers and owners of diesel transport and stationary power generating equipment. In Europe HVO is actively used in such industries as manufacturing, construction and agriculture. The combination of HVO diesel or blends with electricity, the creation of a wide range of fuel additives as well as the further improvement of fuel production processes, including new raw material types and the maximization of by-products generated in the process are seen as particularly promising. Due to the gradual withdrawal from fossil fuels due to the depletion of their reserves and the high level of environmental damage, the industrial production of HVO should be seen in Russia, especially since the country has both the necessary areas for planting the appropriate crops (such as rapeseed), and sufficient oil and fat waste and technical capabilities for the transition to more advanced fuels.
