2. Try to sketeh the residue curve map for a system containing three components A,B, and C using - The boiling points for the pure components: A=120.4C;B=100.02C,C=88.4C. the following information. (15%) - There are two binary azeotropes. (1). A=20mol%,B=80mol%,T=97.2C; (2) B=40mol%, C=60mol%,T=76.5C. - A ternary azeotrope ( A=25mol%,B=25mol%,C=50mol%,T=55.4C ) inside the system
