An automatic control system (ACS) for capturing and utilizing carbon dioxide (CO.sub.2) of one or more gases from one or more plants receives one or more parameters of at least one gas of one or more gases through a system gas flow inlet channel, a first volumetric flow rate of the one or more gases through a plug flow reactor (PFR), a second volumetric flow rate of the one or more gases through a bypass channel that bypasses the PFR, the CO.sub.2 flowing into the CO.sub.2 capture unit, or the syngas flowing into the CO.sub.2 capture unit. The ACS commands one or more flow controllers to modulate at least one of the first volumetric flow rate of the one or more gases through PFR or the second volumetric flow rate of the one or more gases through the bypass channel based on the one or more parameters.
