Below we are presenting the glossary, thanks to which even the most complicated elements will be bright and clear


  • Atmospheric distillation - a physicochemical process used to separate component products of a mixture, using differences in the boiling point temperatures of individual components. In the process of atmospheric distillation, individual fractions of gases, benzene, paraffin and diesel oils become separated. Atmospheric distillation is a process carried out at a pressure close to atmospheric pressure


  • Barrel - a primary unit of measurement used in crude oil production. One barrel contains 159 litres
  • Biofuel - a fuel manufactured by adding more than 5% biocomponents to gasoline or diesel oil


  • CDU/VDU -

    a basic installation system used for crude oil processing comprising a Crude Distillation Unit and Vacuum Distillation Unit

  • CNHT -

    a Coker Naphtha Hydrotreating Unit

  • CS-LF -

    a Coke Storage and Loading Facilities


  • DCU -

    a Delayed Coker Unit


  • Heavy heating oil -

    an oily liquid representing a residue from the distillation of crude oil. Heavy heating oil finds its use in industrial installations of large manufacturing or processing facilities, as well as in combined power plants. It is also used as bunker fuel for ships

  • HGU -

    (Hydrogen Generation Unit) a system for hydrogen production


  • Light heating oil - a product obtained in crude oil processing characterized by lower sulphur content and density than heavy heating oil. LHO is mainly used in household boiler rooms, in SMEs and institutions. It is also successfully used as the heating fuel in the boiler rooms of residential estates
  • LPG - a liquefied gas, being a mixture of propane and butane, obtained in the processing of crude oil. Among its other applications, LPG is used as engine fuel or as fuel for household gas stoves
  • LPGTU -

    a LPG Treating Unit


  • OGU -

    an Oxygen Generation Unit


  • Vacuum distillation - a process analogical to the process of atmospheric distillation, conducted, however, at a reduced ambient pressure. It uses a physical property, whereby the boiling point decreases as the ambient pressure is reduced. It makes it possible to separate vacuum distillates in the atmospheric residuals. Heavy remnants of the distillation process are so-called vacuum residuals
