摘要

Graphical abstractEquilibrium total pressure – loading curves for Aqueous of AEEA (Total concentration of unloaded solvent?=?10?wt%) solution (○:T?=?313.2?K; □:T?=?328.2?K; Δ:T?=?343.2 K; ?:T?=?358.2?K and solid line: correlating by Deshmukh-Mather).Display OmittedHighlights?Equilibrium solubility of hydrogen sulfide in aqueous amine solutions of AEEA have been measured in temperature range of 313.2–358.2?K and pressure range of (9.5–1594)?kPa.?Two different concentrations of AEEA aqueous solutions (10 and 30?wt%) have been studied.?The equilibrium solubility of H2S in aqueous solutions of AEEA were correlated by the Deshmukh-Mather model with AAD%?=?5.0.?The enthalpy change of the absorption of H2S in the 10 and 30?wt% aqueous solutions of AEEA was also estimat
