field-erected towers can only be tested on-site once built

This paper correlates chiefly noise data measured at Exxon process plants into a prediction technique for estimating induced draft cooling tower noise in communities adjacent to a plant

lowest cost to implement approaches were those most often implemented

89-01: Reducing Copper Corrosion and Discharge Via a Novel Inhibitor and Cooling Tower Water Treatment Programs metallurgyThe 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.
