Question 1: (Distillation) 30 marks A fractionating column is required to distil a liquid containing 49% of component A and 51% component B (mol basis), to give a product of 90% (mol basis) of A. A reflux ratio of 4.5 is to be used, and the feed will enter at 90C. The waste product should not contain more than 15% (mol basis) of A. (0) (0) (iii) Mr (A) = 78.12 kg.: kmol 1: Mr (B) = 92.15 kg.; kmol; Heat of vaporization is 25 000 kJ.kmol, and Specific heat capacity 150 kJ.kmol-1K-1.
