| 제목 | Process design and optimization of membrane process for CO2 removal from NGCC flue gas |
| 초록 | It is accepted that carbon capture from natural gas power plant flue gas is challenge due to a low CO2 concentration in the flue gas. In order to tackle this issue, we proposed novel membrane process with 3 design options. First, a increased CO2/N2 selectivity of membrane module in the cold temperature is contributed to separate CO2 from huge amount of flue gas. Also, LNG regasification replaces the conventional refrigeration system. Last, the methodology of EGR and S-EGR enhances the feed CO2 fraction from 4 % to 6 – 10 %. These options finally reduce the CO2 capture cost to $ 57/tCO2(- 55.1 %) and parasitic load to 54.8 MW (-70.1 %) against existing sub-ambient membrane process. In addition, the sensitivity analysis is carried out in cases of varied CO2/N2 selectivity and CO2 permeance for analysis of how membrane system can be improved.
