Measurement and modeling of solubility of H2S in aqueous Diisopropanolamine solution

In this work the apparatus similar to the device of Hayduk and Chen (1970) which had been improved by Pahlavanzadeh and Motahhari (1997) for the measurement of gas solubility data by the synthetic method was used for the experimental determination of hydrogen sulfide solubility data in aqueous Diisopropanolamine (DIPA) solution in the concentration range of 30-40 mass% and temperature range of 313-343°K at atmospheric pressure. The experimental solubility data of DIPA were used to predict the interaction parameters of modified UNIQUAC-NRF model for calculating the activity coefficient.
