INDUSTRIAL ORGANIC CHEMISTRY- March 4th, 2016 SURNAME: __________________ NAME: __________________ ID NUMBER: ________________ A steam reforming reactor is fed with methane and water with a molar ratio of . The inlet mixture is at 550 °C and 30 bar. The exit stream consists of . By assuming: The reacting mixture is an ideal mixture of ideal gases The thermodynamic equilibrium is reached at the outlet of the reactor The total methane conversion is 80 % 1. Assess and justify how many reactions has to be considered to evaluate the thermodynamic equilibrium conditions 2. Evaluate the composition of the stream leaving the reactor 3. Calculate the temperature of the stream leaving the reactor Temperature 4. Evaluate the heat exchanged Heat Exchanged Thermodynamic data: Steam reforming reaction: TTG SRR 25.60537170 , [cal/mol] where T in [K] Water gas shift reaction: TTG WGSR 71.785140 , [cal/mol] where T in [K] Reference state: ideal gas at 1 atm 23 ,p i i i i ic (T) a b T c T d T (cal/mol/K) H0 F(298K) [cal/mol] a b x 103 c x 106 d x 109 H2 0 6.483 2.215 -3.298 1.826 CO -26420 7.373 -3.070 6.662 -3.037 CO2 -94050 4.728 17.54 -13.38 4.097 CH4 -17890 4.598 12.450 2.860 -2.709 H2O -57800 7.701 0.4595 2.521 -0.859
