Methanol (CH3OH) and its derivative products are used as base materials in acrylic plastic, synthetic fabrics, adhesives, paints and as chemical agent in pharmaceuticals and agrichemicals. In petrochemical industry, one promising pathway to produce methanol is from conversion of syngas to methanol via hydrogenation of carbon dioxide and carbon monoxide. The reaction of this process is given as follows, СО+ 2H2 СНзОН (1) CO2 + H2 → CO + H20 (2) Suppose 1000 kmol/hr of syngas with molar composition of 22% CO2, 6.7% CO, 65% H2, 4.1% H2O, 1.1% CH4 and 1.1% N2 is used as fresh feed. (a) Draw and label a complete process flow diagram of this process. (b) Calculate the amount of unreacted CO2 if given single pass conversion of CO2 is 14.2%. (c) Calculate the extent of reaction for the side reaction (2) and the amount of water produced.
