The phase and volumetric behaviour measurements of a five-component synthetic gas condensate are presented. Vapour-liquid equilibrium volume measurements were performed by carrying out constant composition expansion (CCE) tests at 278.15, 303.15, 313.15, 333.15, 353.15 and 383.15K. The pressure change was in the range of 10.45-41.47MPa. A high-pressure-high-temperature oscillating tube densitometer was employed to measure vapour-liquid equilibrium phase densities at 303.15 and 353.15K and various pressures. © 2002 Elsevier Science B.V.
