1. Vapor-liquid equilibrium data for mixtures of carbon dioxide (1) and n-butane (2) at 0C are given in Table 1. a. Prepare Pxy and xy diagrams and label the regions and curves. Use paper or computerbased plotting tools. Do not draw free-hand. b. You are tasked with separating a single phase mixture containing 95mol% carbon dioxide at 0C and 1.5atm. Is this initial mixture in vapor or liquid phase? c. When this mixture is compressed, what is the pressure at which the two-phase system is first created? What is the composition of the liquid and vapor phase? d. At an applied pressure of 30atm, what is the vapor liquid composition? Report the corresponding K-values for carbon dioxide and n-butane. e. What fraction of the feed leaves the separation unit in liquid phase? Table 1: Binary vapor-liquid equilibrium data for a carbon dioxide (1) - n-butane (2) mixture at zero degrees celsius
