Chapter 10 Practice Problem Solutions To accompany Introductory Chemical Engineering Thermodynamics J.R. Elliott, C.T. Lira, 2001, all rights reserved. (07/06/01) 1 of 4 (P10.5) (a) Perform bubble P calculations 1-CO2, 2- ethylene. For kij = 0 Output from PRMIX.exe bp COMPONENT IS CARBON DIOXIDE ID NO. IS 909 COMPONENT IS ETHYLENE ID NO. IS 201 T(K)= 222.00 P(MPa)= .8725 ZL= .2138E-01 ZV= .8674 ID LIQUID X VAPOR Y Yi/Xi 909 .5000 .4057 .8114 201 .5000 .5943 1.189 repeating across the composition range: x1 y1 P(MPa) 0.0 0.0 1.02 0.1 0.0795 0.995 0.5 0.406 0.873 0.9 0.834 0.7012 1. 1. 0.642 End points were determined using bubble point pressure calculation using PRMIX for a single component. No azeotrope exists. Answer is 0.87MPa (b) Output from prmix.exe: Kij MATRIX MODIFIED 909 201 201 .1100 bp COMPONENT IS CARBON DIOXIDE ID NO. IS 909 COMPONENT IS ETHYLENE ID NO. IS 201 T(K)= 222.00 P(MPa)= 1.126 ZL= .2867E-01 ZV= .8358 ID LIQUID X VAPOR Y Yi/Xi 909 .5000 .4237 .8475 201 .5000 .5763 1.153 For kij = 0.11 x1 y1 P(MPa) 0.0 0.0 1.02 0.1 0.139 1.09 0.5 0.424 1.126 0.9 0.691 0.882 1. 1. 0.642 at small x1, x1<y1. At large x1, x1>y1. Also, P maximum in mixture. Therefore, maximum P (minimum T) azeotrope will exist. Answer is 11.3 bar.
