The primary aliphatic amine Primene JM-T was investigated as a potential absorbent for H2S removal.The solubility of H2S in JM-T was measured at 298,313,333,353,and 368 K with H2S partial pressures from 20 to760 kPa and H2S loading from 0.02 to 0.8 mol H2S per mol JM-T.Relevant physical properties,such as density,viscosity and dielectric constant,of the material were measured.The thermodynamic model with two-suffix Margules equation was used to correlate the experimental vapor-liquid equilibrium data.Furthermore,the absorption mechanism in non-aqueous system is suggested and the difference between non-aqueous and aqueous absorption system is pointed out.

The solution of H2S in JM-T was measured at 298,313,333,353, and 368 K with H2S partial pressures from 20 to 760 kPa and H2S loading from 0.02 to 0.8 mol H2S per mol JM-T. Recipient physical properties, such as density, viscosity and dielectric constant, of the material were measured. The thermodynamic model with two-suffix Margules equation was used to correlate the experimental vapor-liquid equilibrium data. absorption mechanism in non-aqueous system is suggested and the difference between non-aqueous and aqueous absorption system is pointed out.
