*12.15 Hydrogen, important for numerous processes, can be produced by the shift reaction: CO+ H2O CO2 + H2 In the reactor system shown in Figure P12.15, the conditions of conversion have been adjusted so that the H2 content of the effluent from the reactor is 3 mole %. Based on the data in Figure P12.5: (a) Calculate the composition of the fresh feed. (b) Calculate the moles of recycle per mole of hydrogen produced.
