TP26-24 Bacteria Management Strategies for Refineries and Chemical Plants Driveshafts

TP26-24 Bacteria Management Strategies for Refineries and Chemical Plants DriveshaftsRefineries and chemical plants have a robust opportunity to manage bacteria proliferation in cooling waters due to the development of new inline sensors and additional bacteria test methods that can measure reduced heat transfer efficiency and increased health risks from biofilm. This paper starts with the awareness of risks by key stakeholders in industrial plants, followed by current operating and turnaround practices and the associated assessment

In the last few decades

plant processes

By precisely matching fan motor speeds to the required building heat rejection

Because of that concern

poor design

The temperature threshold effect may explain why ozone treatment has been reported as a successful treatment for air conditioning cooling systems

equipment selection procedure

The produced by-product solids contain over 90% solids

the frequency of dosage and selection of product are rarely tailored to the particular system for optimum control

then increased operating costs for the unit involved are incurred from the very beginning

Information will be presented on the above issues

Recommendations to update ATC-128 will be proposed to improve the correlation of results between the codes
