Modeling of the process of retaining the concentration of aggressive gases during the operation of deaerators

Abstract

In this article, in the process of deaeration of feed water in thermal deaerators in the saturation temperature range of 20-105 °C, a method is proposed for determining changes in partial pressure, absorption coefficient and concentration values of aggressive gases such as carbon dioxide, oxygen and nitrogen in the gas phase and dissolved in water is modeled according to Henry’s law, and the results obtained are graphically depicted; conclusions are given on how the correspondence of the saturation temperature to an increase in pressure affects the change in the concentration of aggressive gases.
