Carbon monoxide at 25C and saturated steam at 150C are fed to a continuous water-shift reactor. The product gas, which contains 40.0 mole% H2, 40.0 mole% CO2 and the rest H2O(v) emerges at 500C at a rate of 3.5 SCMH, and goes to a condensor, where all of the H2O is condensed. The gas and liquid streams leaving the condensor are at equilibrium at 15C and 1 atm. The liquid leaving the condensor can be assumed to be pure water (no dissolved gases).
a) Calculate the % excess steam fed to the reactor and rate of condensation of the water (kg/h).
b) Calculate the rate (kW) at which heat must be removed from the condensor.
c) Taking atomic species at 25C as references, prepare and fill in an inlet-outlet enthaply table and calculate the required heat rate of heat transfer (kW) to or from the reactor.
