Density Behavior of CO2 + Decane Mixtures by Modified SAFT Equation of State

AbstractThe capture of CO2 and its storage in depleted oil reservoir is one of the most important technologies for reducing CO2 emissions. The knowledge about the CO2+hydrocarbon binary mixtures plays an important role in the design and operation processes involved in CO2 enhance oil recovery (CO2-EOR). In this work, densities of CO2+decane were predicted with PC-SAFT and tPC-PSAFT equations of state. Some modification of tPC-PSAFT has been done combined with existing experimental data, and the prediction results were improved markedly with the modification
