TECHNOLOGIES

The enterprise was designed and built in accordance with the process scheme of the fuel type of an oil refinery. The main complex of process units was constructed in the 1970s, then reconstructed and brought into compliance with the relevant process standards. The main designers of the projects of construction and reconstruction of the process units were such major design and engineering organizations as LENGIPRONEFTEKHIM, All-Russian Scientific Research Institute for Oil Refining, VNIPINEFT, UOP, KOCH GLITSCH.

Technological structure of the complex comprises the following units:

  • crude distillation units (AVT-1, AVT-2, AVT-6, АТ-3, АТ-8);
  • diesel fuel and kerosene hydrotreatment (L-24/6, L-24/7, LCh-24/7, L-24-9х2);
  • catalytic reforming (L-35-11/300, L-35-11/600, L-35/6, LCh-35-11/600, LG-35-8/300B);
  • paraxylene, UOP PAREX, ethylbenzene, mixed xylenes, orthoxylene, pseudocumene;
  • selective solvent oil refining (A-37/1, A-37/3, VT-1);
  • oils dewaxing (39/7, 39/7M);
  • VR deasphalting (36/4);
  • bitumen (19/5, 19/6);
  • sulfuric acid;
  • additives to lubrication oils (alkylphenol, succinamide, sulphonate);
  • cogeneration gas turbine plant (CGTP);
  • automated lines for bottling of lubrication oils into small package for vehicles;
  • automated lines for bottling of solvents for consumer purposes in small package.

Besides, OJSC Naftan possesses an extensive tank farm with tanks of 5, 10, 20 thousand tons capacity, loading/unloading racks, wide transport network including railway, serving to receive and store feedstock and oil products.

The refinery carried out and continues automation of technological processes, tankage facilities, and accounting of power and utilities consumption.

IN HARMONY WITH THE ENVIRONMENT

Environment protection and rational use of natural resources is one of the top priority directions in the enterprise activity.

Industrial and consumer wastes from the refinery undergo a full cycle of deep cleaning at the waste treatment facilities including the units of mechanical, physical and chemical, and biological purification.

Naftan introduced a state-of-the-art system of local monitoring that ensures continuous control over discharge into the atmosphere and open waters, with further analysis of air and water basins.

The depth of purification of industrial wastes of the plant often exceeds similar parameters at many industrial enterprises of Western Europe and America.
