文摘

In previous research, a cryogenic system based on Stirling coolers has been developed. In this work, the novel system was applied on CO₂ capture from post-combustion flue gas and different process parameters (i.e. flow rate of feed gas, temperature of Stirling cooler and operating condition) were investigated to obtain the optimal performance (CO₂ recovery and energy consumption). From the extensive experiments, it was concluded that the cryogenic system could realize CO₂ capture without solvent and pressure drop condition. Meanwhile, the results showed that for post-combustion, the novel SC system can capture above 80 % CO₂ from flue gas with 3.4 MJ/kg CO₂.
