1. 100 kg/h of a feed mixture containing three species namely A, B and Care fed into a distillation column. The feed contains 50% A by mass and equal quantities of B and C. This feed mixture is separated into an overhead top stream (distillate) which consists 90% A by mass and no C. The bottom stream does not contain any A. (a) Draw the flowchart of the process. (b) Perform degree of freedom analysis. (c) Calculate the mass flowrate and composition of the top and bottom streams
