摘要:
The solubility of nitrous oxide (N2O) in aqueous solutions of 0-50 mass % methyldiethanolamine (MDEA), 0-30 mass % diethanolamine (DEA), and 50 mass % total amine with DEA/MDEA weight ratios of 0.04413-0.5883 was measured over the temperature range 293-353 K and at N2O partial pressures near atmospheric. The solubility data from this work were found to be in fair agreement with the literature where data were available. The N2O solubility data for the aqueous MDEA and aqueous DEA solutions were fitted using the extended scaled-particle model proposed by Li and Mather (1994) (which was based on the work of Hu et al. (1985)). The parameter estimates obtained from these fits were then used to predict the N2O solubility in the aqueous DEA + MDEA solutions. The model predictions were found to agree with the experimental data with an average deviation of 3.4%
