초록

An experimental apparatus was constructed to obtain vapor-liquid equilibrium data for $CO_2$/oil mixtures using mass analysis method with sample cylinder. Lubricants employed were POE(Polyol Ester) oil and PAG(Poly Alkylene Glycol) oil. The phase equilibria of $CO_2$/oil mixtures formed in high pressure equilibrium cell are observed through sight glasses at the opposite ends. Data were measured over the temperature range from -10 to $10^{\circ}C$ with $5^{\circ}C$ intervals under pressures up to 14 MPa. Mole fractions were calculated for $CO_2$/oil and $CO_2$/PAAG, respectively and were compared with each other.
