Oksidatif pada gandingan metana (OCM) adalah proses yang menjanjikan untuk menukar metana menjadi etilena. Walau bagaimanapun ia mengalami pemilihan etilena yang agak rendah pada penukaran metana yang tinggi. Dalam kajian ini, perisian simulasi, Aspen Plus digunakan untuk mensimulasikan tindak balas, mengkaji kesan keadaan operasi terhadap prestasi reaktor pengoksidaan reaktor metana (OCM) dan pengoptimuman tindak balas. Hasil simulasi yang diperoleh boleh diterima kerana kesilapan yang dikira untuk produk kurang daripada 10%. Analisis sensitiviti yang dijalankan menunjukkan penukaran metana dan selektiviti etilena adalah maksimum pada suhu reaktor, tekanan, nisbah metana kepada oksigen, dan kadar aliran metana pada 880 oC, 1 bar, 8 dan 3500kmole / jam. Pengaruh parameter operasi utama seperti suhu, tekanan, nisbah makanan metana ke oksigen, dan kadar aliran metana pada prestasi reaktor OCM akan dianalisis lagi. Dari pengoptimuman, ia menunjukkan bahawa pemilihan metana maksimum dan kepelbagaian etilen masing-masing adalah 96.8% dan 26%. Reaksi telah dioptimumkan pada 887 oC, 1 bar, 3980 kmole / hr kadar aliran suapan metana dan metana kepada nisbah makanan oksigen sebanyak 9.

An oxidative coupling of methane (OCM) is a promising process to convert methane into ethylene. However it suffers from the relatively low selectivity of ethylene at high methane conversion. In this study, simulation software, Aspen Plus is applied to simulate the reaction, study the effect of operating conditions on the performance of the oxidative coupling of methane (OCM) reactor and optimization of the reaction. The simulation results obtained is acceptable since the error calculated for the product is less than 10%. Sensitivity analysis conducted shows that the conversion of methane and selectivity of ethylene were maximum at reactor temperature, pressure, methane-to oxygen feed ratio, and methane flow rate at 880 oC, 1 bar, 8 and 3500 kmol/hr respectively. The influences of key operating parameters such as temperature, pressure, methane-to oxygen feed ratio, and methane flow rate on the OCM reactor performance are further analysed. From the optimization, it shows that the maximum methane conversion and ethylene selectivity are 96.8% and 26% respectively. The reactions have been optimized at 887 oC, 1 bar, 3980 kmol/hr methane feed flow rate and methane to oxygen feed ratio of 9.
