One of the most difficult to process is oil supplied to the Samara Group and nearby region’s enterprises, due to its high corrosiveness. The IFO process reagent package based on its own patented inhibitor made it possible to achieve the target corrosion rates at JSC Syzran Refinery, Saratov Oil Refinery PJSC and JSC Novokuibyshevsk Oil Refinery. As a result, a decision to start the procedure for IFO reagents admission to be used in the kerosene TS-1 production at one of the largest units in the region – AVT-11 JSC Novokuibyshevsk Refinery, was made.
