77-01: The Evaluation of Nonchromium Low Zinc Cooling Water Corrosion Control Manual

77-01: The Evaluation of Nonchromium Low Zinc Cooling Water Corrosion Control ManualOverall performance achieved with a nonchromium low zinc cooling water corrosion control agent is reviewed, Duration of the test extended over almost a year of additive usage in a major cooling tower of the Shell Oil Company Wilmington Manufacturing Complex. This evaluation was the last in a comparative study of ten commercially available additive formulations1 the others contained neither chromium or zinc. Coupon corrosivities measured in the present

This paper describes how the application of a newly developed high cycle cooling water treatment program directly resulted in a substantial savings in water use and overall cooling water treatment costs while maintaining scale and corrosion control

in view of today's rules and regulations concerning pollution abate­ment

The limited cooling capacity of the HL&P W

it's important to understand the deterioration mechanisms operating and how best to mitigate the damaging effects before performing repairs and placing them into service

conducted in several regions

The paper will discuss several modifications that can be made to existing crossflow and counterflow towers to enhance overall energy savings

Some of the difficulties and anomalies encountered when computing separate heat and mass transfer coefficients from wet cooling tower fill test data are presented

The criterion of efficiency in every single phase of industry today is without question

a process was patented (1) utilizing an anion exchange resin to selectively remove chromate ions from waste water

while the supplies of uncontaminated water dwindle

Comparisons between a universal motor design and a more traditional motor design concept will be made
