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.
You can get the n2o.zip file to compute N2O solubility.
The file contains
- Fortran source code
- neural model parameter file
- solubilty data bank
