97-13: PGDP Enhances Plant RCW Reliability Oxidizing BiocidesThe recirculating cooling water (RCW) system has served the Paducah Gaseous Diffusion Plant (PGDP) since 1951. Over the years, there have been changes to the system: cooling tower additions, cooling tower replacements, pump upgrades and the installation of a cathodic protection system. However, the basic system of headers and piping remains the same as the original construction. This paper will illustrate the problems experienced in a 40+ year old
Computational results are capable of reproducing the main feature of the plume
and new technology in every industry over the past decade
as part of a robust cooling water treatment program
dispersant and chelant variety are discussed in detail along with their effect on fouling materials
which rejects the heat to the atmosphere
An alternate method using the measurement of the conductivity of the filter washing water is easy to perform on-site
The new program utilizes new chemistry that is completely halogen stable and provides performance far superior to that obtained with the industry-standard phosphonate and azole (tolyl triazole)
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
For rotating machinery utilizing drive shafts
detect upsets and take appropriate corrective action becomes increasingly important as systems are pushed harder to reduce total cost of operation
It includes two specific case studies of creosote cooling towers in the Gulf Coast area
