METHOD FOR WATER DECARBONIZATION Russian patent published in 2000 - IPC

FIELD: applicable in thermal power stations and boiler plants for preparation of feed water. SUBSTANCE: in the offered method for water decarbonization desorption of carbon dioxide from water is accomplished at a contact of treated water and free air, which feed flash steam to the decarbonizer, and remove decarbonized water from the decarbonizer. Rate of flow of air fed to the decarbonizer is controlled in accordance with the value of preset concentration of carbon dioxide in decarbonized water, which provides for maintaining the optimum rate of flow of air fed for decarbonization. EFFECT: enhanced economical efficiency and quality of decarbonization. 1 dwg
