Question 1.3: A mixture consisting of 1 mol-% ethane, 5 mol-% propane, 44 mol-% n-butane, and 50 mol-% isobutane is bro...
(1) A mixture that is 20 mol% propane, 35 mol% n-butane, and 45 mol% n-hexane is fed into a flash drum operating at 400 kPa. (a) What is the highest temperature at which the flash drum can operate and still have vapor and liquid present? Use the DePriester chart for equilibrium. (b) If the flash drum operates at 50°C and 200 kPa. Find the vapour to feed flow ratio, liquid mole fractions, and vapor mole fractions.
Question 1.2: A mixture contains ethane (1), propane (2), isobutane (3) and isopentane (4). If the temperature is maintained constant at 60 °C. Using De-Priester calculate; (a) the bubble point pressure, given xl-0.10, x2 0.20, x3 0.30 (b) the dew point pressure, given y1-0.48, y2-0.25, y3-0.15 13 marks] Question 1.2: A mixture contains ethane (1), propane (2), isobutane (3) and isopentane (4).

The stream "1" consisting of yP1 mole % propane and yEl mole % ethane is blended with the stream "2" containing propane alone and the stream "3"containing nitrogen alone in a mixer in order to produce a gas mixture at Qp inch'/hr. The gas mixture produced with the streams "I". "2", and "3" contains xPP mass % propane, XEP mas % ethane, and XNP mass % nitrogen. The pressure and temperature of the product stream are PtPpsig and TP®F, respectively....
