摘要：The 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. (C) 2014 The Authors.
