1. Compute the equilibrium vapor and liquid compositions for the following LPG (Liquefied Petroleum Gas) mixture at 30°C and 3.8 bar. Assume that the LPG mixture behaves like an ideal solution. Use Antoine equation for vapor pressure calculations (do your calculations at n= 0.700 and 0.718). Fill in the following table to summarize your findings. Do calculations by hand and do not use any spreadsheet application. Component Mole fraction Propane (CaHe) -Butane (-CaH1o) n-Butane (n-CaHso) n-Pentane (n-CsH12) 0.210 0.030 0.700 0.060 Σ 1.000 Also calculate bubble and dew point pressures, vapor composition at the bubble point pressure and liquid composition at the dew point pressure at 30°C. Remember that at the bubble point pressure xz and at the dew point pressure yz. NL= 0.718 @ Putele @ Poe XI Propane -Butane n-Butane n-Pentane Remember that y, @ bubble P=, (x, ==) x@ dew P
