5. Draw a block flow diagram for the vinyl-chloride process, in which the three main sections in the process namely, ethylene chlorination, pyrolysis, and separation-are shown, together with the principal flow topology. Note that the diagram also indicates the overall material balances and the conditions at each stage, where appropriate. Information/data: C12 113,400 lb/hr, C,H, 44,900 lb/hr; Direct Chlorination 90C, 1.5 atm; Pyrolysis 500C, 26 atm; HCI 58,300 lb/hr, C2H3CI 100,000 lb/hr; CH.CI, Recycle, 105,500 lb/hr.(15 points)
