Do you have any experience in this.

Failures in the HP condenser can usually be traced back to corrosion and salt deposition. These mechanisms are controlled with water washes at the main fractionator overhead condenser, the LP condenser and the HP condenser. The effectiveness of these washes is monitored by regularly checking the pH, and composition of the water being drawn from the water boots of these same condensers. It is also important to make sure that the rate of water injection is sufficient to assure wetting of all surfaces in the condenser. It sounds like you might have some spots near the end of the tubes where water is not reaching. In such a case you could be measuring good quality water but still seeing some corrosion.
