Description
Summary:The many years of experience in the use of sorbents of hot-contact coal carbonization (HCCC) in the power industry is used for substantiation of their prospects for solving problems of power and materials saving and improving the reliability and safety of operation of power equipment. Results of tests of sorbents in systems of water conditioning of thermal power plants, cleaning of return condensates, mazut- and oil-contaminated process wastewaters, makeup water in heat networks, and biosorption cleaning of sewerage are presented. The sorption methods of cleaning are shown to have many advantages, to save expensive ion-exchange resins and reagents, to decrease the cost of desalinated water, and to prolong the service of power equipment. Comparative data are presented for basic commercial kinds of activated carbon and HCCC (sorbents activated crushed brown-coal coke (ABD)). The technical characteristics of sorbents of hot-contact coal carbonization are shown to be at the level of commercial sorbents or be higher at a much lower cost (by a factor of 2.5 - 3). It is shown that the creation of several HCCC installations with an output of 25 - 30 thousand tons of sorbents a year at coal-fired power plants will solve many water-cleaning problems of the 'EES Rossii' Co. ('The United Power Systems of Russia') and make it a monopolistic producer of activated carbon in the Russian market.
