Abstract

The pressure of gas condensate reservoir will decrease at the production process. The reduction of pressure under dew point causes gases to condensate into two phase systems i.e. vapor-liquid and its composition. The prediction of phase equilibrium constant of vapor liquid and its compositions is obtained by applying Peng-Robinson equation. Especially for component of hepthane plus (C7+), a new correlation is proposed to determine equilibrium constant gas-liquid and its composition. The data used in this study was field data from several gas wells in Sumatera and Java. The results are an equilibrium constant and a composition as a function of pressure, temperature, specific gravity and molecule weight. The use of a new correlation to other components of gas condensate system (C1–C6 and CO2–N2), gives a good agreement with the standard data in a PVT chart.
