Résumé

Trans-critical CO2 quasi-combined cycles (e.g. OCDOPUS, COOPERATE) were introduced to promote zeroemission fuel-fired power-unit concept. A 0.35-0.49 efficiency is reported in spite of extra-power consumption for O2 production and CO2 condensation. Author improved concept elaborating further COOLENERG process operated by a CO2 quasi-combined two-stage gas-turbine with CH4 gas burning in O2 / recycled CO2 mixture.
It originally uses an advanced absorption cooling plant (AACP) supplied by internal recovered heat to decrease CO2 condensation isothermal below internal sink source temperature (TISS). This brings COOLENERG ~1.09 times more net power efficiency comparatively (ηel,net = 0.539; TISS = 20℃). This work replaces AACP with single-stage absorption refrigeration (AR) and applies recent effective gas liquefaction for O2 supply. Carnot-ized plant model shows net power efficiency is ηel,net = 0.5654; 0.5674; 0.5758; 0.5845; 0.5923; 0.5999; 0.6014 for TISS = 20; 18; 9; 0; −9; −18; −20℃. Noting nowadays
plants mitigating CO2 have net power efficiency lower by ~0.08, results recommend COOLENERG consideration for future clean power generation.
