| Summary: | 碩士 === 中原大學 === 化學工程研究所 === 84 === The equilibrium solubility of mixture of carbon dioxide and
hy- drogen sulfide in aqueous mixtures of diethanolamine ( DEA)
with sterically hindered amine, 2-amino-2-methyl-1-propanol
(AMP) has been measured at 40 ℃ and 80 ℃ at partial pressure
of the acid gases between 0.1 and 200kPa.The systems selected
for this study are six blended amines solutions (total 30wt％)
consisting of 30 wt﹪ DEA, 24 wt﹪DEA＋6 wt﹪AMP, 18 wt﹪DEA
＋12 wt﹪AMP, 12 wt﹪ DEA＋18wt﹪AMP,6wt﹪DEA＋24 wt﹪AMP,30wt﹪
AMP.The solubility mo- del of Deshmukh and Mather has been
used to represent the data. The model reproduces reasonably the
equilibrium partial pressur- es of CO2 and H2S above the
solutions for the systems tested.
