Pentane is burned with air in a continuous steady-state combustion reactor to

Pentane is burned with air in a continuous steady-state combustion reactor to yield a mixture of carbon monoxide, carbon dioxide and water. The fresh feed to the reactor contains 7215 kg/s pentane and 117450 kg/s air. The process is to be designed for a 96% overall conversion of pentane. The reaction products are separated into two streams: first stream is stack gas which contains CO2, CO, H20 and unreacted inlets and 23.8% of the pentane that leaves the reactor leaves the process from this stream. The second stream contains only some part of the unreacted pentane and it is combined with fresh feed and recycled to the reactor. The stack gas contains 4mol CO2/mol CO. a. Draw the flow chart. b. Carry out a degree of freedom analysis. c. Calculate the molar compositions of all streams. d. Calculate single pass conversion.
