URGENT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The process for the production of yinly chloride from ethylene is shown in the following block diagram. Each block represents a reactor and sexeral other processing units. The main reactions are: Chlorination (A) Oxyhydrochlorination (B) C2H4+Cl2C2H4Cl2, vield on ethylene 98 per cent C2H4+2HCl+1/2O2C2H4Cl2+H2O, xields: on ethylene 95 per cent on HCl90 per cent Pyrolysis (C) C2H4Cl2C2H3Cl+HCl, yields: on DCE 99 per cent on HCl99.5 per cent The HCl from the pxrolysis step is recycled to the exyhydrochlorination step. The flow of ethylene to the chlorination and oxyhydrochlorination reactors is adjusted so that the production of HCl is in balance with the requirement. The conyersion in the pyrolysis reactor is limited to 55 per cent and the unreacted dichloroethane (DCE) separated and recycled. Figure 1. The block flow diagram of production of vinly chloride Using the yield figures given, and neglecting any other losses, calculate the flow of ethylene to each reactor and the flow of DCE to the pyrolysis reactor for a production rate of 12,500 kg/h yinyl chloride ( VC).
