"We do not object to applying additional internal thermal insulation (based on ceramic compositions) with a High Emission Coefficient on the lining and on the external surface of the heating pipes for raw materials for the furnaces of the LK-6U installation (JSC "Achinsky Refinery VNK" of PJSC "Rosneft") in order to improve there thermal efficiency."

The Letter from JSC "Gazpromneft - Omsk Refinery" to LLC "LENGIPRONEFTECHIM" of PJSC "Surgutneftegas" dated May 4, 2017 Ref. No.78.10961
We inform you that from 2012 to the present [5 years at the time of writing the letter], the ceramic coating on the furnaces of the KT-1/1, Aromatics Production Complex, AVD-6 installations of JSC “Gazpromneft – Omsk Refinery” has been in an undamaged state.
During the period of operation of the furnaces after the use of HEC, a stable positive effect is observed in reducing the temperature of the wall of the furnace coils by an average of 100-150 ° C, increasing the efficiency of the furnaces to 3%, saving fuel by an average of 3-5% (depending on the type of furnace and the ratio of liquid and gas fuel).
The fuel used in the furnaces of these installations is combined (fuel gas and liquid process fuel). The fuel ratio varies depending on the production program, there are periods with the consumption of liquid process fuel up to 50-60%, at this time the share of liquid fuel is 10-30%.
Alexander Nikitin, Deputy General Director - Technical Director of JSC "Gazpromneft - Omsk Refinery"
