1. A chemical process uses a distillation column to separate a feed stream comprised of 14.0 mol.-% carbon disulfide (CS) 5.0 mol.-% chloroform (CHCI), 66.0 mol.-% carbon tetrachloride (CCL), and 15.0 mol.-% diethyl ether (DEE). The bottoms product contains 3.3 mol/s CHCI, 258.1 mol/s CCl, all of the entering DEE, and no CS. The overhead product entering the condenser contains 90% of the entering CHCl, and is 29.4 mol.-% CS. The distillation column operates with a reflux ratio of 71.4%, meaning that 71.4% of the liquid condensate is returned to the column as reflux. Draw and completely label the process flow diagram and write equations for any process specifications using the notation provided on the diagram
