1. Consider the following mixture going into a water-gas shift reactor to make hydrogen for the hydrogen economy. CO, 630; H2O, 1130; CO2, 189; H2, 63 kmol/h. The gas is at 1 atm and 500 K. Use MATLAB and at least three iterations manually to compute the specific volume using (a) ideal gas law (b) Redlich-Kwong equation of state (c) Redlich-Kwong-Soave equation of state. The acentric factors for the RK-Soave method are: CO, 0.049; water, 0.344; CO2, 0.225; Hydrogen, -0.22. Where did you get the other data you needed? How do the three answers compare? Is the gas ideal or not? Comment. Then redo the calculations for a pressure of 200 atm and comment on the results.
