89-01: Reducing Copper Corrosion and Discharge Via a Novel Inhibitor and Sound

89-01: Reducing Copper Corrosion and Discharge Via a Novel Inhibitor and SoundThe A. B. Hopkins Generating Station operates under severe copper discharge limits of 30 ppb at the discharge point. A program of continuous feed of 3 ppm of Tolyltriazole reduced Admiralty Brass corrosion rates from 1. 5 mpy to 0. 15 mpy, and copper discharge from 400 ppb to 120 ppb. A new proprietary inhibitor, which is feed for 10 minutes every 3 weeks to 5 ppm active reduced corrosion rates to 0. 0w mpy and copper discharge to 20 25 ppb.

Not too many years ago when air conditioning installations were pretty well confined to funeral parlors and barber shops and people were wondering if it really paid to air condition an office

Within Cooling Towers

the conclusions will become prescriptive

freezing and winterization

what is it about corrosion that allows all these factors - many apparently unrelated - to be possible causes

In this regard

The pulsation force is a combination of the aerodynamically generated pressure difference between the upstream and downstream side of the fan blade and the velocity (under) pressure generated by the surface of the blade tip

The removal of such scales is often a complex mechanical or chemical process and the up-front prevention of their formation is a much desired solution to the problem

This paper will discuss potential hazards on a cooling tower jobsite

including compliance field-testing
