Isothermal Vapor-Liquid Equilibria of Binary Mixtures of Nitrogen with Dimethyl Sulfoxide, N-Methyl-2-pyrrolidone, and Diethylene Glycol Monobutyl Ether at Elevated Pressures
Weng, W. L.[Wen-Lu], Chen, J. -T.[Jui-Tang], Yang, J.-W.[Jei-Wai]
High-pressure vapor-liquid phase equilibrium (P, x, y) were measured for the binary systems of nitrogen + dimethyl sulfoxide, nitrogen + N-methyl-2-pyrrolidone, and nitrogen + diethylene glycol monobutyl ether over a temperature rage between (323.15 and 393.15) K. In addition to the new data, the Soave-Redlich-Kwong, Peng-Robinson, and Patel-Teja equations of state accompanied by several types of mixing rule were also used to correlate these vapor-liquid phase behaviors. In general, the Patel-Teja equation incorporated with mixing rule-C (linear temperature-dependent combining rule for aij) yielded the best representation.
