Oxy-combustion is a competitive technology to capture CO2. Current air separation technologies for high volume O2 production are based on cryogenic distillation. When a double-column distillation cycle is applied to produce O2 with a purity of 95 mol%, the oxygen production process is causing...

A novel methanol-based power system with Chemical-Looping Combustion (CLC) is proposed in this paper. CLC system is a promising approach to greatly decrease the energy penalty for CO2 removal, where iron oxides circulate between two reactors and an inherent CO2 separation occurs. The combustion...
