Abstract: This paper summarizes the problems occurred in the operation of a 600 t/h desalination plant using ion exchange resin method, such as the vibration of steam condensate main pipe, the shedding of the lining of carbon steel lined plastic pipe and the shedding of the internal anti-corrosion of water storage tank. The reasons for these problems were analyzed, and the corresponding improvement measures were taken to eliminate the hidden dangers in system operation. The original process of the system was optimized, the load of plant was effectively reduced under normal working conditions, and the cooling capacity of the effluent was reused. Through a series of modification measures, the operation stability of the plant was improved and the energy consumption of the plant was reduced

Key words: ion exchange resin, desalted water, improvement measure
