Conclusions
-
1.
Commercial tests have been performed on the inhibitor IKB-4, and the following have been established: (a) with an inhibitor dose of 50 mg/liter (calculated on makeup), the rates of corrosion and sediment formation in shell-and-tube heat exchangers are reduced on the average by 93 and 54%, respectively, (b) The IKB-4 inhibitor gives the circulating water a certain amount of detergency, so that the overgrowth rate decreases by 50%.
-
2.
Before treating the circulating water with IKB-4 inhibitor, the system must be prepared by cleaning the heat exchangers, oil-separator tanks, and pans and intake chambers of the cooling towers to remove silt and slime.
-
3.
Studies in pilot-scale water blocks have furnished data from which optimal regimes have been selected for treating circulating water with corrosion and scaling inhibitors, along with chlorine.
