Abstract-The solubility of nitrous oxide (N2O) in 13 amine solvents and solutions was correlated to amine mole fractions and temperature using feedforward neural networks. This general correlation, using a massive data base, predicted N2O solubility at temperatures between 283 K and 398 K in pure solvents: H2O, monoethanolamine (MEA), diethanolamine (DEA), methyldiethanolamine (MDEA), 2-amino-2-methyl-1-propanolamine (AMP), in binary aqueous amine solutions: H2O/MEA, H2O/DEA, H2O/MDEA, H2O/AMP, and in ternary aqueous amine blends: AMP/MDEA/H2O, AMP/DEA/H2O, DEA/MDEA/H2O, MDEA/MEA/H2O, AMP/MEA/H2O. Combined with “N2O analogy”, this present improved correlation can be advantageously implemented in an amine plant design software and procedures for the prediction of CO2 solubility in amine blend solutions over wide temperature and concentration ranges.
