Abstract

Cooling systems are very important for the functioning of industry and energy facilities. The most common problems in open cooling systems are: corrosion, deposits and biological growths. In this work we covered the subjects of: causes and effects of deposit creation and the protection of the cooling system against deposit creation. The dosage of inhibitors - deposit preventing agents was determined experimentally, with and without dosing corrosion inhibitors. Polymaleate was used as a deposit inhibitor here. The results showed that the success of deposit inhibition depended on the degree of thickening, i.e. the salt concentration in the system. Another important factor is the use of corrosion and deposit inhibitors. In the case of using corrosion inhibitor based on phosphonates, the consumption of polymaleates is decreased by up to 30% due to the synergetic effect of phosphonates and polymaleates.
