Desorption of carbon dioxide from monoethanol ethylene diamine solution with the use of SHF was compared to the thermal technology both in static condition and with a fixed absorbent expenditure. In the static condition, CO2 evacuation by SHF was more complete, without precipitation, and within a short interaction time. With absorbent expenditure and CO2 production rate permanent, SHF desorption occurred at a lower temperature and, therefore, lower absorbed power than the conventional thermal process. Testing demonstrated efficiency of the non-inertial volumetric SHF heating in regeneration of the liquid absorbent charged in physicochemical life support systems for different pressurized habitats.
