Conclusion and Evaluation
In the filtration tests performed with the filtration of Filternox® NTU Terminator filters;
At Refinery Clean Tower Point:
- TSS removal was achieved on average of 47% in one stage and 67% in two stages.
- Turbidity removal was achieved on average 56% in one stage and 73% in two stages.
As a result of the filtration to be performed in the cooling line with Filternox® NTU Terminator filtration system;
- Lifetime of the tower filling will increase
- The amount of chemicals used in the system will be reduced
- The amount of tower blowdown water will be reduced
- Cooling efficiency will be increased
- Unnecessary stops / work interruptions will be prevented
- Operation, maintenance and energy costs will be reduced
- The cooling line will be protected from particles
With all of these mentioned benefits, cooling efficiency is increased incredibly.
