Report dated 31.01.2013 of the Heat Engineering Survey of Furnaces of the AVD-6 Unit after one annual inter-repair run of the Unit
Analysis of completed work:
The actual economy of equivalent fuel on comparative loads of 1.3 kg per ton of raw materials (4.6%). At the same time, the actual (currently) negative ambient temperature is a lowering factor (about 0.5 kg equivalent fuel per 1 ton of raw materials), because these furnaces operate on injection burners. The comparative graph is in Appendix 3.
Conclusion:
The implemented measures aimed at energy efficiency of the furnaces correspond to the expected effect (the declared effect was 3.5% fuel economy).
Furnace Blackening Technology (FBT) was proposed as the Best practice for furnaces of JSC “Gazpromneft - Omsk Refinery” in 2016
The Letter from JSC “Gazpromneft - Omsk Refinery” to LLC “LENGIPRONEFTECHIM” of PJSC «Surgutneftegas»
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%.
