99-15: Online Cooling Tower Cleaning and Water DivisionThis paper highlights specific problems associated with a Cold Water Basin Cleaning in an eleven (11) cell cross flow cooling tower in Northern Alberta at the Syncrude Canada Site. The cleaning involved structural modifications of nine (9) of the eleven (11) cells and a diversion of 100,000 gallons of water per minute to maintain plant operation. This would be the first cleaning of the tower in 20 plus years of operation and two major hydrogen mishaps

In light of these developments

adjuvant material that increases the efficacy of oxidizing and non-oxidizing biocides against bacteria both in biofilms and in cooling water

This paper discusses the development and application of a new alkaline cooling water treatment program that is completely halogen stable

Every cooling system operates under stress

the filter operational reliability is high and the operation and maintenance costs are extremely low

without significant problems

A project was started in which the water distribution system and the splash pack grids of four existing natural draft cooling towers at a large petrochemical plant were to be replaced without shutting down the water flow to the cooling towers

The purpose of this paper is to discuss what is involved in changing the shade for the Cooling Tower applications and what pitfalls could occur with other pigmentations

and instrumentation to be used for testing and evaluating the performance of evaporatively cooled
