All the environmental advantages of semi-closed gas turbine cycles as to an absence of NOx and the release of non-diluted (in N2) CO2 in the flue gas stay the same.  An effect of integration becomes apparent with the following clarification. Assigning the efficiency of syngas production in the integrated cycle a value equal to a regular syngas production efficiency through steam-methane reforming (some part of methane is combusted to drive endothermic reforming), the net-power generation efficiency (with accounting for the consumed electricity required to separate air) can reach levels higher than 60% at a maximum temperature in the cycle (at the gas turbine inlet) of about 1300 °C.
