Plot Vapor Liquid Equilibrium For Component

Question

The equilibrium concentration of component A of in the vapour phase yA, with concentration of component A in liquid phase, XA, can be given by:

yA = xAPAo/P

and

xA = (P - PBo)/ (PAo – PBo)

where P = system pressure

PA°, P B° = saturated pressure of component (A) and (B) respectively.

(a) Briefly indicate the laws used to obtain these relationships.

(b) Plot the Vapour Liquid Equilibrium (VLE) curve (xA, yA) using the data given in Table Q5 and assuming that the benzene - toluene system will be maintained under an absolute pressure of 760 mmHg.

TABLE Q5

 Temperature/°C Vapour Pressure/ mmHg PAo (benzene) PBo(toluene) 82.2 845 310 84.1 880 330 90.6 1080 410 97.3 1330 505 104.4 1640 620

Summary

The question belongs to Chemical Engineering and it discusses about plotting Vapor Liquid Equilibrium for a component in liquid phase and vapor phase.

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
