Power Generation from Coke Oven Gas Using Chemical Looping Combustion: Thermodynamic Simulation

Abstract A chemical looping combustion (CLC) combined cycle with coke oven gas as fuel and NiO/NiAl 2 O 4 as an oxygen carrier is proposed. The system was simulated by Aspen Plus® and the oxygen carrier circulation ratio was calculated. The effects of key operational temperatures and different gas turbines on the system performance were investigated. Under optimized conditions, a high CO 2 capture efficiency could be achieved. To capture CO 2 thoroughly, the PG6561B gas turbine can be employed, allowing for nearly 100 % CO 2 capture efficiency.
