While it is true that most syngas production routes use
high purity O2, this paper’s focus is on flue gas, which comes
from the combustor in power plants and already contains a
certain amount of N2. It is generally very costly to separate N2
from the flue gas, and for this reason, the N2 separation unit is
not included in the overall process. As is well established in
the literature [31], N2 has an adverse impact on methanol
conversion. However, the reactor type adopted in this simulation
was an equilibrium reactor that already takes into
