Project, supply of equipment and construction of gasoline hydrotreating and isomerization unit are fulfilled by corporation JGC Corporation (Japan) on technology of UOP firm (USA).

General designer of the enterprise – is JSC "Nizhegorodniinefteproekt."

2006 - commissioning of the Unit.

Gasoline hydrotreating and isomerization unit includes:

  • section of hydrotreating and stabilization of gasolines from atmospheric distillation unit and delayed coker unit;

  • section of division of wide petrol fraction for a purpose of allocation of BP-85 C fraction

  • section of isomerization of BP-85 C fraction.

Section of gasolines hydrotreating and stabilization is intended for purification of gasolines from sulfur, nitrogen - and oxygencontaining hydrocarbons on the special catalyst in the presence of hydrogen, and also stabilization of gasolines from section of diesel fuel hydrotreating and dewaxing unit by a rectification method.

Design capacity of the section of gasolines hydrotreating and stabilization on raw material in continuous work 330 days/year is:

  • on the node of hydrotreating - 470 000 tons / year (60 tons / h);

  • on the node of stabilization - 554 000 tons / year (70 tons / h).

Production: hydrotreated gasoline, liquefied gas.

Section of division of wide gasoline fraction is intended to increase the octane number of wide gasoline fraction by distillation of low-octane components C5 - C6 from its composition.

Design capacity of the section on raw material, including gasoline from existing hydrotreating unit is - 870 000 t / year (110 t / h).

Production: fraction BP-85 C (raw material of  isomerization), fraction BP 85-180 C (raw material of reforming).

Isomerization section of fraction BP-85 C is used to increase the octane number by its isomerization on the special catalyst in the presence of hydrogen.

Design capacity of the section of isomerization on raw material is:

173 300 tons/year (22 t/h). Production: isomerizate (high octane component).

Characteristic of finished product:Mass fraction of sulfur, ppm no more – 0,5

Concentration of actual resins, mg / 100 cm3 of petrol , no more- 5,0

Volume fraction of benzene,%, no more - 3

Appearance – pure, transparent.
