PROBLEM 2 A hydrocarbon system is flashed in a drum at 325 psig and 300 K. Assume that the system obeys Raoult's Law and Antoine's equation is sufficient to model their vapor pressures. Antoine's Coefficients Component A B с Feed Composition Methane 6.6956 405.4200 267.7770 0.1300 Ethane 6.8345 663.7000 256.4700 0.1700 Propane 6.8040 803.8100 246.9900 0.3500 Butane 6.8090 935.8600 238.7300 0.2900 Pentane 6.8763 1075.7800 233.2050 0.0600 Antoine's equation is given by: B log psat (mmHg) = A-; T (°C) +C a. Calculate the bubble P and dew P of the said feed mixture. b. Determine the composition of the vapor and liquid streams and the fraction of feed vaporized. c. If the feed rate is 1000 mol/h, what are the flowrates of the liquid and vapor streams?
