Abstract:
A recurring problem of industrial cooling systems is deposition
of particulates brought into the cooling system from outside the
unit and those particulates generated within the system.
Polymers and co-polymers have been applied with considerable
success to specific types of particulates. The types of
particulates can be quite varied depending on both the treatment
and the nature of the water. Frequently, a single polymer or
co-polymer is effective in one specific application and much
less effective in another. One solution to this problem is the
use of a variety of materials. Another is the use of blended
polymers. The latter is often desirable for both cost of
treatment and the effectiveness. This paper deals with methods
of determining a blend of polymers for optimum adsorption and
effectiveness for a particular solid phase found in a cooling
system. The method measures the adsorption of polymer on a fixed
amount of slurry of solid phase. The polymers used are chosen on
the basis of the overall isotherm and the slope in the Henry's
Law region of the isotherm. By using the isotherms for the
individual polymers and the isotherm for the blend, the maximum
adsorption can be obtained. The liquid for the slurries of
material can be distilled water, system make-up, or cycled
make-up. Several temperatures are run to give an indication of
the effect of temperature on adsorption. Illustrations of the
application of the technique and field application of the
results are given.
