Ethylene can be produced by the thermal cracking of ethane

C$3$H$6->$C$2$H$4+$H$2$

C$2$H$6->0\mathrm{.}5$ C$2$H$4+$Ch$4$

The reaction takes place at $1500$ oF and $50$psia. We desire to produce $875$ mol$/$hr of

ethylene with $75\%$ purity. Assume that the selectivity is given by S$=$ mol C$2$H$4$ Formed$/$ mol C$2$H$4$ Converted$=1-0\mathrm{.}0381/(1-$x$)^0\mathrm{.}241$ The ethane feed contains $5\%$ CH$4$ and cost $$1\mathrm{.}65/$mol$.$ Ethylene at $95\%$ composition is

worth $$6\mathrm{.}15/$mol$.$ Fuel is worth $$4$x$10^-6$ per Btu.
