摘要	In this work, experimental hydrate dissociation pressures of the (tert-butylamine + CO2) and (tert-butylamine + N-2) systems were reported at (0.005, 0.015, 0.03, 0.056 and 0.093) mole fraction of tert-butylamine with measurements made in the temperature range of (273.5 to 283.3) K and in the pressure range of (2.27 to 13.79) MPa. The equilibrium data were generated using an isochoric pressure-search method. The hydrate dissociation data for the (CO2 + water) system were obtained in advance and compared with experimental data reported in the literature, and the acceptable agreements demonstrate the reliability of the experimental method and apparatus employed in this work. Dissociation experimental. results indicated that tert-butylamine had an inhibition effect on the dissociation conditions of carbon dioxide, shifting the dissociation conditions of CO2 hydrate to lower temperatures/higher pressures, while for the (tert-butylamine + N-2 + water) system, tert-butylamine showed a hydrate promotion effect, which meant higher temperatures/lower pressures would be required for the formation of hydrate. The inhibition/promotion effect was the highest at 0.0556 mole fraction of tert-butylamine within the experimental range.
