Abstract—

The range and current quality level of cation-exchange resins available in the Russian market and intended for use in thermal power plant water treatment installations (WTIs) are analyzed. The article outlines changes that have emerged in the Russian market for the recent years and involved a significantly updated and extended range of cation-exchange resins that resulted from appearance of ion-exchange resins from new producers and new trademarks as well as new types of ion-exchange materials developed especially for dealing with various technological matters to be settled in the treatment of water at thermal power facilities. The article presents the main producers of ion-exchange resins and the types of cation-exchange resins offered by these companies to Russian customers. For determining the potential possibility of using new types of cation-exchange resins and confirming the quality of resins that have long been used in WTIs at domestic power industry enterprises, laboratory tests of samples in regard to the technological and physicochemical indicators characterizing their consumer properties were carried out. The results from comparison tests carried out on the samples of different types of cation-exchange resins produced by different manufacturers are considered, and the competitiveness of Russian types of resins is estimated. The modern quality level of the produced cation-exchange resins is estimated. It is established that, as of now, there are no cation-exchange resins whose quality complies with the requirements of the relevant state standard (GOST) issued in the former Soviet Union. It is also shown that the requirements of the regulatory document are not consistent with the quality of the produced cation-exchange resins that has been established taking into account the modern trends in the development of water-treatment technologies. The changes that occur in the quality and range of produced cation-exchange resins should be taken into account in drawing up the technical requirements for procuring ion-exchange materials and in selecting them.
