85-15: Study of Cooling Water at High CyclesThe decreasing availability of high quality water, high pumping costs and environmental regulations are driving cooling water systems towards higher cycles, brackish makeup and zero discharge. This paper presents solutions to the difficulties of recommending chemical treatments for such systems. The methods used to obtain phase diagrams incorporating the kinetics of mineralization rather than pure equilibrium thermodynamics is discussed.

Also included are future plans for softening hot cooling tower blowdown water in a separate treat­ment plant

For given ambient conditions

Significant reductions in mechanical properties were found and consistent relationships between awl penetration and mechanical properties were observed

The benefits of proper control are measurable and translate to improved system efficiency and reliability

Frequent questions include: What test methods should be used to develop scale inhibitor performance data

In areas where water conservation

It was found that seawater cooling towers can satisfy the cooling needs of large-scale petrochemical development in the hot humid Gulf region
