Estimate the maximum conversion of ethylene to alcohol by vapour phase hydration at 523 K and 34 bar, by the reaction CH4 (g) + HO (g) CH5OH (g) The equilibrium constant varies with temperature as 4760 In K=-1.558 In T+2.22x10T-0.29x106T -5.56 T The steam-ethylene ratio in the initial mixture is 5.0. The fugacity coefficients for ethylene, ethanol and water vapour are 0.98, 0.84 and 0.91.
