We are interested in determining the vapor-liquid equilibria for the system of n-Butane and n-Pentane at 14.7 psia. You may assume that the mixture behaves ideally and Raoult's law can model it's properties. Use Antoine's equation for the vapor pressure. Calculate the boiling points of the two pure substances at this pressure. Use about 8 points (including the boiling points and approximately well- spaced) and plot the Txy diagram. For this, you may use Excel. However, you are expected to use one representative temperature and show how the calculations are done. You can print out the plot and table from Excel. A 40/60 (butane/pentane) mixture flowing at 100 kmol/h and 14.7 psia is heated so that 50% of the feed is vaporized. Assuming the vapor and liquid streams are in equilibrium, calculate the flow rates, composition of the vapor and the liquid. Also calculate the temperature of the vapor leaving the system.
