CHE 3333 - Separation Processes Dr. Bui Homework 1 Due: 10 AM Tuesday, March 1", 2022 SUBMISSION OF ANSWERS (DOC, PDF, XLS FILES) ON CANVAS Problem 1 (30 points) A group of engineers is exploring a binary system of benzene (l)and m-xylene (2) They want to calculate the vapor and liquid phase splitting and the compositions of the respective phases of this system when an equimolar mixture of benzene (1) and m-xylene (2) is flashed at T-37C dp -0.1 atm. Initially they assume that benzene (1) and xylene (2) follow Raoult's law, and calculate the flash products using the following Antoine equations benzene logammHgD6.90565 - (1211.033 / (TCC) + 220.791) -xylene log/pmmHg) - 7,00908 - 1462.266 (TCC) +215,051) One of the team members found the experimental data for this system at T-37C (published by Benson G.C. "Molar Excess Gibbs Free Energies of Benzene-m-Xylene MixturesCam. J. Chem 47 (1969) 539-542). The experimental data are tabulated as follows VAPOR-LIQUID EQUILIBRIUM DATA FOR BENZENE AND -XYLENE AT 37C Moll Blue PaPa LiquidV 0.017 0.296 300 0.012 314 0.012 sol 47 7.341 9.21 0619 076 0.137 0.26 94 0474 0.535 0651 0.745 0:19 09 0.916 0948 18.07 2009 971 1.
