GlobeCore develops and manufactures inline continuous USB biodiesel1Biodiesel refers to a vegetable oil- or animal fat-based diesel fuel consisting of long-chain alkyl (methyl, ethyl, or propyl) esters blending2A blending is the process of mixing. systems, designed for compounding of fuels and any other liquid ingredients, including bioethanol3Bioethanol is an alcohol produced from organic biomass such as sugar, wheat or maize, and represents over 80% of global biofuel production. and liquids of vegetable origin.

These biodiesel blending systems come in several types, can be designed stationary or mobile (installed on trailers, in vans or on railroad flatbed cars etc). The client specifies the type ingredients and the final product for customization of the unit. The blending units be used to produce any fuel blens: summer diesel4Diesel fuel in general is any liquid fuel used in diesel engines, whose fuel ignition takes place, without any spark, as a result of compression of the inlet air mixture and then injection of fuel., winter diesel, arctic diesel, Euro-45European emission standards define the acceptable limits for exhaust emissions of new vehicles sold in the European Union and EEA member states (Euro-1, Euro-2, Euro-3, Euro-4, Euro-5, Euro-6). high-octane gasoline6A Gasoline is a colorless petroleum-derived flammable liquid that is used primarily as a fuel in spark-ignited internal combustion engines., Euro-5 fuel etc.

The main purpose of these systems is intensification7An intensification is an increase in strength or magnitude (or intensity). of dispersion8A dispersion is a system in which distributed particles of one material are dispersed in a continuous phase of another material., homogenization9Homogenization or homogenisation is any of several processes used to make a mixture of two mutually non-soluble liquids the same throughout. This is achieved by turning one of the liquids into a state consisting of extremely small particles distributed uniformly throughout the other liquid. and emulsification10An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable). and blending of seemingly immiscible liquids and suspensions. The final product is a steady mix, which remains stable for a long time.

Hydrodynamic continuous mixers:

This type of equipment includes compounders, cavitators11Cavitation is a phenomenon in which rapid changes of pressure in a liquid lead to the formation of small vapor-filled cavities, in places where the pressure is relatively low., blenders, dispersers, homogenizers etc.

Light and dark petrochemical material production

This includes production of various materials from oil (high quality 95 octane gasoline, bio-gasoline, Euro-compliant diesel fuel, light heating oil16Heating oil is a low viscosity, liquid petroleum product used as a fuel oil for furnaces or boilers in buildings., dark heating oil, heavy oil according to Euro-4 standards, paints, biodiesel etc).

Our units and solutions are designed for:

  • Compounding of multi-component mixes to produce motor fuel, biogasoline and biodiesel, to improve octane number17An octane rating, or octane number, is a standard measure of the performance of an engine or aviation fuel. The higher the octane number, the more compression the fuel can withstand before detonating (igniting). of low-octane fuel etc;
  • Production of multi-component combustion18Combustion is burning a fuel in oxygen, which gives out heat energy and is called an exothermic reaction. fuels: water-fuel emulsions, water-oil emulsions for boilers, blending of various liquids and mixing additives to liquid fuels;
  • Production and preparation of diesel fuel, production of winter and arctic fuel by mixing in anti-gel and anti-freezing additives, economizing of heating fuel, water-oil emulsions, heavy fuel and coking industry products.

Our USB units have been supplied to over 53 countries, to hundreds of industrial facilities, where they are operated in all climate zones with temperatures from -65 to +55oC.

All USB unit types are very simple to operate, easy to install, have a small footprint and come complete with full documentation and installation assistance service.

The blended gasoline production units are built for 5 to 600 tons per hour capacity for 2 to 7 ingredients.

Each unit is designed for a specific client, according to client requirements. The equipment can easily be integrated into existing processing equipment.


Compounding means mixing two or more fuel, oil or other ingredients to achieve specific product parameters.

Processing of oil and petrochemical products in the USB units occurs under highly intensive hydrodynamic and cavitation conditions, created by the sharp drop of pressure in the hydrodynamic (also known as trans-sonic) jet mixer with powerful physical influence on the processed fluid.

The method and technology of treatment in a subsonic flow is capable to change the structure of the fluid, increases light fraction yield, improves such properties as viscosity, sulfur and paraffin composition, accelerates additive mixing when making blended gasoline, water-fuel emulsion and mixes, oils, greases and other fluids.

The unit is designed for petrochemical facilities, filling stations and refineries. Besides, the technology and the equipment is widely used in over 400 industries, such as paint production, food production, mining, metallurgy, perfumery etc.

The compounding units are used for:

  • Blended fuel production;
  • Blended gasoline production;
  • Blending diesel with biodiesel;
  • Blending gasoline and bioethanol;
  • Production of winter diesel fuel;
  • Production of arctic diesel fuel;
  • Improvement of hydro sulfur removal by pretreatment of distillates in production of modern environmentally clean fuel;

Our compounding units have a range of advantages, and first of all, it is a complete unit easily integrated into any production cycle.

Results of USB unit implementation

The USB units are operated by many heating facilities successfully, as illustrated by the results of commissioning and operational tests of boilers of varying capacity, which use heavy heating oil and water-oil emulsion for fuel, with water content 8-20% (boilers tested in similar operating modes):

Parameter changes when burning fuel-water emulsion fuel Savings of heating oil depend on combustion equipment (boilers, burners) and original fuel oil parameters. Saving range is 8 to 20%. The amount of emissions to the atmosphere drops by 70-75%, soot emissions decrease significantly Bottom water disposal is not required, bottom water is distributed uniformly in the fuel oil. Boiler reliability improves, since loss of flame due caused by water in the fuel is eliminated entirely. Uniformity of combustion is improved. The amount of solid deposits on the walls of the boiler and gas ducts is reduced.
