at a specific molar ratio of 0.1:0.2:0.03:0.67 [6]. Throughput of
flue gas was selected as 1000 kmol/h as a basis for this
simulation. Inlet temperature of flue gas was set to be 150 C,
which would be a typical temperature of gas exiting the flue
stack. Methane, a co-feed, was mixed with the flue gas via a
mixer at 25 C. M1 is a mixer block and no specifications were
added to it. The inlet stream conditions determined the outlet
stream conditions
