  • flare system of the facility;
  • park of pumping equipment;
  • heat exchange system of the facility.
2) From 2000 to 2003 the vacuum unit of the facility was reconstructed thanks to which the nomenclature of the output production got the valuable oil product "vacuum gas oil" and the depth of oil refining (including the light and target oil) reached to more than 70%.

At the moment the design - survey works on the third consecutive reconstruction of CDU/VDU-7, the goal of which is:
  • modernization of the facility according to modern rules and regulations of industrial safety with increasing depth of oil refining and raw materials for its performance up to 110% of the existing one.
