Effect of Hydrogen Sulfide Loading on the Density and Viscosity of Aqueous Solutions of Methyldiethanolamine

The change in the density and viscosity of aqueous methyldiethanolamine on the addition of hydrogen sulfide was investigated in this study. At 25 °C densities and viscosities were measured for loadings up to 0.5 mol of H2S per 1 mol of amine for amine concentrations up to 50 mass %. Solution densiti...

Description
Summary:The change in the density and viscosity of aqueous methyldiethanolamine on the addition of hydrogen sulfide was investigated in this study. At 25 °C densities and viscosities were measured for loadings up to 0.5 mol of H2S per 1 mol of amine for amine concentrations up to 50 mass %. Solution densities and viscosities were measured at 40 °C for an amine concentration of 50 mass % and for H2S loadings up to 0.5. It was found that the solution density increases with H2S loading whereas the viscosity decreases as the H2S loading increases.
