Оцінка ефективності реагентів для стабілізаційної обробки води циркуляційних систем

The problem of stabilizing treatment of water for cooling systems is very relevant for the energy industry. Increasing water quality will reduce the volume of water discharged during purging of the systems. This, in turn, leads to a reduction in the contamination of natural water bodies. This publication considers both already available and synthesized reagents. Oxyethylidenediphosphonic acid was used to compare the efficiency of antiscalants. The known reagents under study include gipan, carboxymethylcellulose, citric and tartaric acid, and nitriletrimethylphosphonic acid. The efficiency of reagents has been evaluated as for stabilization of tap water and model solutions with different mineralization for different temperature conditions. The efficiency of a number of reagents is determined as for the СaSO4 precipitation from concentrated solutions. The possibility of using available and synthesized reagents for water stabilization at higher temperatures is evaluated. Tartaric and citric acids are quite effective stabilizers in the concentrates of the reverse osmosis seawater desalination. A new inhibitor of precipitation of sodium methyldisulfonate is synthesized on the basis of sodium sulfite and formaldehyde; its efficiency is subject to evaluation.
