Provocarea
The ISO OCTANE refinery operated batch-wise with limited cooling loop circulation during non-production periods. Heavy fouling caused by organic material was found during inspection of the cooling water system. The biofilm affected all pipes, valves, cooling towers and heat exchangers. Despite biocide treatment, heavy growing of algae was found at the cooling tower.
Soluția Merus
Multiple Merus Rings were installed at strategic locations throughout the cooling water loop. The system was then run at full capacity to flush out existing deposits.
Rezultate
→Within two months, the existing fouling had vanished and inner surfaces of the pipes started to get clean. The corrosion rate decreased from 8.5 mpy to less than 1.5 mpy in two months.
