Abstract
The invention is a process for increasing the system thermal capability of a splash filled cooling tower where cooling water is circulated and splashed against splash bars during the cooling process. The process comprises contacting the circulating water of the cooling tower with a nonionic surfactant composition in an amount effective to increase the system thermal capability of the cooling tower.
Claims20
A process for increasing the system thermal capability of a cooling tower comprising:
- contacting the circulating water of the cooling tower with a nonionic surfactant composition in an amount effective to increase the system thermal capability of said cooling tower, said nonionic surfactant composition comprising at least one nonionic surfactant having the following characteristics:
- (a) a hydrophobic segment;
- and
- (b) a hydrophilic segment;
- such that the average HLB of the nonionic surfactant composition is from 9-12;
- monitoring the thermal capability of said cooling tower;
- and adjusting feeding of said nonionic surfactant when needed based upon the said monitoring.
