Dear all
We are facing with a issue of failure of copper strip corrosion of jet fuel product for a long time (1 month so far) even many adjustments of operating conditions of the kerosene treating unit have been taken. The unit is Merichem's licences, Merox technology.
The failure occurs at the inlet (rundown from distillation unit) and outlet streams of the unit.
We already checked:
- NaOH concentration of the Napfining: OK;
- Caustic circulation rate: OK;
- Water wash at Aquafining: OK;
- Water wash rate at Aquafining: OK
- ...
We really do not know the root causes of this issue. It may be from the crude compositions or other.
We are planing to replace salt at Salt dryer, Clay at Clay filter.
Please help to find solutions.
Thanks and best regards.
