The potential of a zero emission combined power generation plant fired by liquefied natural gas (LNG) has been investigated. The thermodynamic cycle proposed is basically an integration of a combined cycle power generation plant, an air separation unit (ASU), and a carbon dioxide (CO2) recovery unit, while the by-products are liquefied CO2, gaseous nitrogen (N2) and water (H2O). LNG is burnt in oxygen (O2)-CO2 mixture and recirculated in a gas turbine-steam turbine combined power generation plant. Such recirculation leads to flue gas with very high CO2 concentration. O2 for combustion is obtained from ASU. LNG is used in both cooling the air for the ASU and to condense a part of the flue gas. By integrating the ASU and the combined power generation plant, the overall thermal efficiency calculated is around 47% (LHV).
