In this paper results of investigations of N2O absorption in water MDEA solutions were discussed. The solubility of gas was determined in amine solutions at a total pressure of 0.3 MPa in the temperature range 293 - 333 K. Values of mass transfer coefficients of N2O in water MDEA solutions were determined and correlated with physicochemical properties of the system in the form of dimensionless equation Sh = f(Re, Sc).
