Abstract:
Cooling tower is a fundamental piece of equipment in any processing plant. As water
is used as a cooling medium in a cooling tower, there is a tendency of biocides
formation. Chloride ions are used in the form of NaOCl + NaBr to remove the biocides
so that they don’t corrode any equipment that uses cooling water. The problem
doesn’t end here, the chloride ions reach the limit where make-up water is added in
order to compensate for the loss of chlorinated water and the use of makeup water
is not cheap. Our project is to treat this chlorinated water by using a chemical
compound that will not only do the job of removing the biocides but also to keep the
chloride ions concentration under the threshold value to avoid addition of makeup
water. A full-fledged chemical dosing facility is designed for this purpose.
