METHOD OF DEAERATION Russian patent published in 2011 - IPC C02F1/20 

FIELD: process engineering.

SUBSTANCE: invention relates to heat exchange equipment and may be used fort deaeration in make-up water heating in nuclear power plant water preparation system. Proposed method consists in that nuclear power plant forced circulation and heat exchange systems are fed by chemically desalted water fed via feed water circuit into separator to be mixed therein with its boiler water. Corrosive gases are removed from make-up water by heating ahead of saturation line. For this, steam bled from separator steam circuit is used with contact in deaeration column. Deaerated water is drained from deaeration column into bypass line communicating condenser with feed water pipelined feeding water into separator.

EFFECT: higher efficiency and reliability of nuclear power plant.
