The relevance of research is to ensure and improve the reliability of turbine generators (TG) with a
hydrogen-water cooling system by monitoring the content of dissolved gases in the water of a
hydrogen-water cooling system with monoethanolamine (MEA) – C2H7NO and water vapor in the
cooling hydrogen of the turbine. In this work, the influence of ultrasonic vibrations on the
decomposition of a mixture of water and turbine oil, organic acids (acetic acid - С2Н4О2, formic
acid - СН2О2, oxalic acid - С2Н2О4) or monoethanolamine was determined. The distribution
coefficients values were definedd for the following dissolved gases Н2, О2, N2, СО, СН4, С2Н2,
С2Н4, С2Н6, С3Н6, С3Н8, which are of degradation products of water mix components when
exposed to ultrasonic oscillation in the following system: «dissolved gas – mixture «water +
monoethanolamine» – extractant argon (Ar)». The obtained values of the Кі distribution coefficients
for dissolved gases in systems «dissolved gas – mixture «water + С2Н7NО» – extractant argon
(Ar)» at a temperature of 293 K and a concentration of С2Н7NО at the level of 1 g/dm3
are close to
similar values for dissolved gases in deionized water. The principle flow chart of multichannel gas
chromatograph for detecting dissolved gases in water and steam of water in hydrogen was
developed. Developed flow chart of 4-chennel gas chromatographer for defining dissolved gases in
water includes the one gas chromatographer with conductivity detector, methanator, flame
ionization detector, argon gas-bearing and supplementary gases of hydrogen and air.
