c) In the conventional methanol production, methanol is produced from petroleum product (synthesis gas) via hydrogenation of CO. CO+ 2H2 CH3OH 400 mol/s H2 and 100 mol/s CO are fed to the reactor at 180C and 1 atm where the carbon monoxide is completely consumed. The product gas leaves the reactor at 210C and 1 atm. The standard heat of reaction is -48.99 kJ/mol. The flowchart is shown in figure 2. 100 mol CO/s 400 mol He/s ni mol H2/s n2 mol CH3OH/S 180C 1 atm 210C 1 atm Figure 2 methanol production i) Calculate the outlet molar flowrates, ni and nz.
