Abstract

The solubility of CO₂ in isooctane at 270.8 K, 275.0 K, and 282.5 K and at pressures from (1.46 to 3.64) MPa and the solubility of N ₂ in isooctane at 269.9 K, 274.5 K, and 282.3 K and at pressures from (2.70 to 9.45) MPa were measured. The solubility of CO₂ in isooctane is one order of magnitude greater than that in water at the same conditions. Temperature has no significant effect on the solubility of N₂ in isooctane. The equilibrium compositions of CO₂ and N₂ binary mixtures in isooctane at 273.8 K and at a CO₂ mole fraction range of (0.079 to 0.675) in the gas phase were also determined. The selectivity of CO₂ over N₂ in isooctane ranges from (7.2 to 14.6) at 273.8 K.
