Examination of the Process of Establishment of Equilibrium During the Condensation of a Gas-Condensate System

摘要

Helium was used to model the porous medium, in order to study the effect of porous medium on the establishment of thermodynamic equilibrium. (Sorption effects were ignored.) A system with a gas-condensate factor of 6500 m exp 3 /t at 20 exp 0 C was studied. Presence of helium in the gas-condensate system was found to reduce the deviation from equilibrium; the greatest effect is produced by small additions of helium. The effect also decreases with increasing pressure reduction rate. It is concluded that the presence of the porous medium results in more rapid establishment of thermodynamic equilibrium in the gas-condensate system. 3 figures. (ERA citation 08:004198)
