6. Ethylene can be produced by the thermal cracking of ethane C3H6C2H4+H2 C2H60.5 C2H4+Ch4 The reaction takes place at 1500 oF and 50psia. We desire to produce 875 mol/hr of ethylene with 75% purity. Assume that the selectivity is given by mol C,H, Formed mol C,H, Converted 00381 The ethane feed contains 5% CH4 and cost $1.65/mol. Ethylene at 95% composition is worth $6.15/mol. Fuel is worth $4x10^-6 per Btu. Draw the input output flowsheet and plot economic potential.
