Phase Equilibria of Carbon Dioxide, Propane Hydrate in the Presence of Glucose and Fructose

Article Preview

Abstract:

Phase equilibrium data for the hydrates formed in four three-component systems: CO2 + glucose + water system, CO2 + fructose + water system, C3H8 + glucose + water system, C3H8 + fructose + water system were measured in pressures range of (0.24 to 4.57 MPa) and temperatures range of (274.9 to 283.1 K) at 5% and 10% mass fraction of additives. The experimental data were determined using an isochoric pressure-search method. The effects of glucose (or fructose) on CO2 and C3H8 hydrate formation condition were studied. The addition of glucose or fructose increase the equilibrium pressure of the CO2 and C3H8 to form hydrate, and the presence of 10 mass% concentration of glucose (or fructose) showed more remarkable inhibition effect on CO2 and C3H8 hydrate formation.
