Integrated Coproduction of Power and Syngas from Natural Gas to Abate Greenhouse Gas Emissions without Economic Penalties.

ABSTRACT: Natural gas (NG)-fired power plants are significant greenhouse gas (GHG) emitters because of their substantial CO₂ release. To avoid these emissions, precombustion and postcombustion CO₂ capture alongside oxy-fuel combustion were considered in the literature. However, because of additional energy requirements, these options generally induce an approximately 7-10% decrease in net heat-to-power efficiencies regarding regular NG-air-fired stations without CO₂ capture. To compensate for this declination, in this study, a simultaneous generation of power and syngas (CO and H₂) was proposed in an integrated NG-oxygen-fired gas turbine unit (GTU). Hence, the combustion chamber in the NG-oxygen-fired gas turbine cycle was replaced by an NG partial oxidat
