Membran simulasi untuk memisahkan karbon dioksida daripada gas serombong loji arang batu. Dalam pengkajian ini, Mathcad telah digunakan untuk mendapatkan ketulenan and pemulihan karbon dioksida. Analisa metodologi respon telah digunakan untuk mengoptimumkan ketulenan and pemulihan karbon dioksida. Faktor-faktor yang telah dikaji termasuk nisbah tekanan (X1:100-3000Barrers), keluasan membran (100-1000m2), kebolehtelapan CO2 (X2: 100-3000Barrers), kebolehtelapan N2 (10-100Barrers) dan cut peringkat (X5: 10-90%). Antara objektif pengkajian ini adalah untuk mengoptimumkan ketulenan and pemulihan karbon dioksida (ketulenan and pemulihan karbon dioksida maksima). ANOVA telah digunakan untuk mengkaji analisis statistik. Plot permukaan 3D telah digunakan untuk mengkaji interaksi antara faktor- faktor yang disebut tadi. Keputusan yang telah didapati ialah 44.28 nisbah tekanan, 100.45m2 keluasan membran, 3000Barrers kebolehtelapan CO2, 98.23Barrers kebolehtelapan N2 dan 23.87% cut peringkat. Ketulenan dan pemulihan karbon dioksida yang telah didapati ialah 59.2% dan 12.76% masing-masing. Ketulenan dan pemulihan karbon dioksida yang agak rendah ini telah menunjukkan bahawa membrane peringkat satu tidak dapat menghasilkan ketulenan dan pemulihan karbon dioksida yang boleh bersaing dengan teknologi pemisahan lain.

Simulations of membrane separation were performed for the separation of carbon dioxide from flue gas at coal fired power plant. In this work, Mathcad was used to compute the purity and recovery of carbon dioxide. In order to optimize capture efficiency, the exploited system was optimized using response surface methodology (RSM). The influence of capture conditions on performance was investigated in Box-Behnken. The parameters involved were pressure ratio (X1:1-50), membrane area (X2: 100-1000m2), CO2 permeability (X3: 100-3000Barrers), N2 permeability (X4: 10-100Barrers) and stage cut (X5: 10-90%) The objective of this work is to ascertain the optimal performance of the system (with maximum CO2 purity and recovery). The simulated data was fitted to a second-order polynomial equation using multiple regression analysis and analyzed using analysis of variance (ANOVA). The dimensional response surface plots derived from the mathematical models were utilized to investigate the effect between each parameter on purity and recovery of carbon dioxide. Results indicated that the optimum conditions were: pressure ratio of 44.28, membrane area of 100.45m2, CO2 permeability of 3000Barrers, N2 permeability of 98.23Barrers and stage cut of 23.87%. Under these conditions, the whole process can achieve 59.2% CO2 purity and 12.76% CO2 recovery. It showed that a single-stage membrane separator cannot yield high CO2 purity and recovery simultaneously
