(222z) Experimental Determination of Hydrate Formation Systems CO2 + H2O and CO2 + H2O + n-Heptane

This paper presents experimental results for hydrate formation systems CO₂ + H₂O (from 273.17 to 281.67 K and 12.51 to 37.41 bar) and CO₂ + H₂O + n-heptane (270. 40 to 279.07 K and 9.58 to 24.40 bar) which were determined by the isochoric method using a blind cell supporting pressures up to 300 bar and temperatures from 258.15 to 343.15 K. The temperature control equipment is a PolyScience bath in which employed a water-ethanol mixture as cooling fluid and a ISCO pump for supplying the CO₂ and pressurize the cell. Experimental results for CO₂ + H₂O system were compared with data reported in literature with deviations ≤0.5 bar.
