Abstract—

The quality of the coolant at combined heat and power plants (CHPPs) can be improved by upgrading the water chemistry and its support systems. In the context of this problem, we should analyze the experience gained in operating the equipment, determine the advantages and disadvantages of the employed technologies and apparatuses, and propose promising solutions with the maximum use of reliable and environmentally friendly materials and process developments. A new water chemistry based on amine-containing reagents has been mastered at Russian CHPPs. The paper presents examples of the use of domestic complex reagents under the VTIAMIN brand, which differ from imported equivalents in composition and have been tested in actual applications at CHPPs, in implementing the proper water chemistry in the main and auxiliary coolant circuits. Membrane-based water treatment plants (WTPs) are used at CHPPs together with conventional WTPs. The results of the inspection of several WTPs at CHPPs are presented, and schemes combining ion-exchange and membrane processes are proposed to decrease the consumption of reagents and reduce the amount of effluents with a high process reliability of the equipment. Promising information technologies are widely applied at CHPPs. The potential is demonstrated for developing digital systems for chemical-process monitoring of the water chemistry based on the new generation of Russian-made analyzers.
