Popis: Growing interest in the study of production conditions in the presalt led to the need to study complex systems at high pressures and temperatures, such as up to 70 MPa and up to 393 K. The aim of this work is to obtain vapor–liquid equilibrium data at high pressures and temperatures for hydrocarbon systems with carbon dioxide (CO2). To obtain these data, an experimental setup and procedure using a synthetic cell were designed. Experimental data of the binary system CO2 + cyclohexene (C6H10) and CO2 + squalane (C30H62) over a range of temperature between 303 and 398 K and the ternary system CO2 + C6H10 + C30H62 at various temperatures (318–393 K) and compositions are reported. It is noteworthy that the reported measurements in this work were not studied in the literature, and experimental data may contribute to industrial and scientific interests. The phase behavior of the system was also described using the Soave–Redlich–Kwong equation of state together with Mathias–Copeman alpha function. Interaction par...
