MEA(monoethanolamine) is conventionally used in packed column for post combustion CO2 capture process. However, MEA has disadvantages such as degradation, large amount of thermal energy are required from desorption operation, etc. Furthermore, packed column has lower efficiency than membrane contactor because it has low contact area. In this study, to apply novel absorbent to the membrane contactor, measuring regeneration energy has been conducted in 0.1Nm3/hr membrane contactor process. Also, oxidative degradation was measured at 2% CO2(O2 balance) severe condition. As a result, optimized concentration of novel absorbent from CO2 screening had better stability in oxidative degradation and regeneration energy was decreased than MEA. |
