ABSTRACT

This work measures oxygen concentration in the system MEA/H2O/CO2. A polarographic probe and the Winkler s method have been used in this study. The influence of several parameters have been studied: MEA concentration in the range 100 w = 0 to 80, CO2 loading in the range 0 to 0.5, and temperature from 10 deg C up to 60 deg C. Measurements have been carried out at atmospheric pressure. We show that oxygen concentration decreases as temperature drops, but also as CO2 loading increases. MEA concentration does not affect oxygen solubility.
