Solubility of carbon dioxide in aqueous solutions of amino acid salts
A. F. Portugal; J. M. Sousa; F. D. Magalhães; A. MendesThe solubility of CO2 in aqueous solutions of potassium glycinate was measured in a stirred reactor, at temperatures from 293 to 351 K, for amino acid salt concentrations ranging between 0.1 and 3.0 mol dm(-3) and CO2 partial pressures up to 6 x 10(4) Pa. CO2 Solubility in potassium threonate 1.0 mol dm(-3) was also measured at 313 K. It was observed that amino acid salt solutions can be very interesting for CO...
Carbon dioxide absorption kinetics in potassium threonate
A. F. Portugal; F. D. Magalhães; A. MendesThe absorption of carbon dioxide in potassium threonate aqueous solutions is studied at concentrations ranging from 0.1 to 3 M and temperatures from 293 to 313 K. This study includes experimental density, viscosity, solubility of N2O and absorption kinetics of CO2 (using a stirred cell reactor) data obtained for the various potassium threonate solutions. The diffusion coefficients Of CO2 and potassium threonate...
Characterization of potassium glycinate for carbon dioxide absorption purposes
A. F. Portugal; P. W. J. Derks; G. F. Versteeg; F. D. Magalhães; A. MendesAqueous solutions of potassium glycinate were characterized for carbon dioxide absorption purposes. Density and viscosity of these solutions, with concentrations ranging from 0.1 to 3M, were determined at temperatures from 293 to 313 K. Diffusivity of CO2 in solution was estimated applying the modified Stokes–Einstein relation. Solubilities of N2O at the same temperatures and concentrations were measured ...
