文摘

Direct contact between oil, gases, and water often occurs in petroleum reservoirs and in many refining operations, where the phase behavior study is fundamental to design and optimization. Accurate experimental data and thermodynamic models are required for a satisfactory prediction of phase equilibrium. The objective of this work is to obtain experimental solubility data for the system of carbon dioxide + hexadecane since this organic compound has properties similar to the average properties of Brazilian heavy oil. The carbon dioxide + water system was used to validate the experimental apparatus and to obtain additional data to complete literature reports. The operational conditions used were a temperature range from (303.2 to 323.2) K and a low-pressure range from (51.7 to 535.4) kPa. Moreover, the results were correlated using a simple thermodynamic model to describe the behavior of both systems, demonstrating satisfactory bubble point calculation measurements.
