@article{2018, title={EVALUATION OF THE EFFICIENCY OF THE HEAT EXCHANGER EQUIPMENT WORKING SYSTEMS OF WATER-CIRCULATION SYSTEMS ON COKE PLANTS: Array}, volume={7}, url={https://khg.kname.edu.ua/index.php/khg/article/view/5333}, abstractNote={<p><em>In this paper, the closed turnaround system o</em><em>n </em><em>Kharkiv coke plant is considered, which consists of: pipeline, </em><em>water-supplying </em><em>system, heat exchange equipment with a cooling tower, a system of dumping.  The project is considered as the application of several stages: identification, preparation, implementation, exploitation, post-project audit. Technical appraisal of the work of heat-exchange equipment at coke plants is carried out as part of the overall economic effect of the implementation of the developed method.  It consists of: increasing the service life of equipment and pipes, replacing part of fresh technical water with phenolic wastewater and minimizing wastewater discharges. The purpose of the project is achieved as a result of the technology implementation of </em><em>supplying of water-circulation systems </em><em>through the mixing of </em><em>fresh</em><em> and purified phenolic water after, as well as the use of inhibitory composition in the </em><em>water-circulation </em><em>cycle.</em> <em>To determine the efficiency of heat-exchange equipment plant coke plants </em><em>of </em><em>water-circulation systems in the article was conducted techno-economic assessment of proposed work activities. Calculated economic efficiency, which amounted to 568 977,5 UAH/year.</em> <em>In the article it is established that the application of the proposed technical solutions allows to reduce the amount of discharge of sewage into urban sewer network at 36,000 m<sup>3</sup>/year and consumption of fresh industrial water to 52000 m<sup>3</sup>/year, and increase the service life of equipment from 6.5 to 8 years. These measures help to improve water and environmental situation, rational use water resources of </em><em>the</em> <em>coke-plant</em><em>, that is, to decrease the payment made for consumption of water</em> <em>resources and sewage plant.</em></p> <p><strong><em>Keywords: </em></strong><em>phenolic waste water, water-circulation systems, coke plants, technical and economic efficiency </em></p>}, number={146}, journal={Municipal economy of cities}, author={ and }, year={2018}, month={Dec.}, pages={257–263} }
