Phase behavior for carbon dioxide + ethanol system: Experimental measurements and modeling with a cubic equation of state
چکیده انگلیسی

Vapor–liquid equilibria (VLE) data for the carbon dioxide + ethanol system at 293.15, 303.15, 313.15, 333.15, and 353.15 K up to 11.08 MPa are reported. The experimental method used in this work was a static-analytical method with liquid and vapor phase sampling. The new experimental results are discussed and compared with available literature data. Measured VLE data and literature data for carbon dioxide + ethanol system were modeled with a general cubic equation of state (GEOS) using classical van der Waals (two parameters conventional mixing rule—2PCMR) mixing rules. A single set of interaction parameters was used to calculate the global phase behavior in the binary mixture carbon dioxide + ethanol in a wide range of temperatures (283.3–453.15 K).
