89-17: Cooling Water Operational Experiences at an Ammonia Plant Plume Abatement

89-17: Cooling Water Operational Experiences at an Ammonia Plant Plume AbatementWith the increasing pressures placed on various chemical plants to limit effluent constituents, a greater emphasis has been placed on the cooling tower blowdown. Not only is the discharge concern placed on the commonly used heavy metal corrosion inhibitors such as chromate and zinc, but on other components as well such as ammonia. A review of cooling tower operational experiences is presented to illustrate one plant's method of minimizing the effluent

This paper discusses how mixed oxidants

generalized corrosion

a result rarely achieved using chlorine alone or chlorine with other biocides

Cooling Tower Institute field study on wood maintenance

and test methodology used to assure accurate performance predictions

you may have been associated with the pulp and paper or textile industries where many tons of ClO2 are generated and consumed on-site each day

Laboratory studies indicate that molybdate may be effective when used in conjunction with cathodic and other anodic inhibitors

by clogging film fill surfaces

The aim of this report is to bring to light the serious problems confronting the users of cooling towers and to describe accepted and proven methods of coping with these problems

Committee in 1958

Quebec Government adopted a Regulation for cooling towers maintenance

The technology works primarily on the principals of Controlled Hydrodynamic Cavitation (CHC)
