A method has been investigated for regeneration of CO
2-saturated monoethanolamine (MEA)aqueous solution at low temperature and atmospheric pressure, with a rapid regeneration rateand low evaporation solution loss. The solution of 50 wt % MEA, 35 wt % water, and 15 wt %glycol was saturated with CO
2 through addition of dry ice, and the regeneration rate wasmeasured as a function of temperature and flow rate of an inert gas through the solution in apacked bubble reactor. An infrared CO
2 detector was used to measure the CO
2 concentration inthe flushing gas to determine total percent regeneration over a period of time at a giventemperature. The bubbling flow through the reactor was found to greatly enhance theregeneration rate and total amount of regeneration. It is possible with the packed bubble reactorto regenerate MEA solutions to 40% CO
2 at temperatures below 90
