Enthalpy of solution of CO2 in aqueous solutions of methyldiethanolamine at T=372.9K and pressures up to 5MPa

Experimental enthalpies of solution of CO2 in aqueous solution of methyldiethanolamine (MDEA) of 15wt% and 30wt% are reported. The measurements were performed using a flow calorimetric technique at temperature of 372.9K and pressures range from 0.5MPa to 5MPa. Gas solubilities data at same temperature and pressures were derived from the enthalpy data. Experimental enthalpies of solution are combined with available literature data in order to examine pressure and composition influences.
