Simulation of maleic anhydride production in fixed bed reactor

Simulation of maleic anhydride production in fixed bed reactor / Amirul Hakim Abd Talib
Di dalam kajian ini, simulasi pengoksidaan separa n-butana telah dibangunkan. Aspen Plus V8.8 telah digunakan untuk merangsang, menganalisa, mengoptimumkan proses pengoksidaan separa n-butana dan oksigen. N-butana dimasukkan ke dalam RPLUG model bersamaan 0.0075 pecahan mol dan 0.21 pecahan mol oksigen. Suhu dan tekanan bagi penyuapan aliran di programkan kepada 379.85°C dan 1.6 atm. Diameter untuk reactor adalah 0.0025m dan panjang 1.0m. Pemankin yang digunakan dalam simulasi ini adalah vanadium phosphorus teroksida. Simulasi di dalam Aspen model telah dibandingkan dengan sorotan kajian untuk mengesahkannya. Ujian sensitif telah dijalankan dengan tiga kondisi yang berbeza iaitu suhu, tekanan dan kadar aliran suapan. Dalam pengoptimum, fungsi objektif adalah untuk memaksimumkan pertukaran n-butana. Pengoptimum memberi nilai optimum iaitu kadar suapan n-butana adalah 0.001 kmol/jam dan suhu reaktor pada 550°C. _______________________________________________________________________________________________________ In this study, simulation of partial oxidation n-butane was developed. Aspen Plus V8.8 was used for stimulated, analysed, and optimized process partial oxidation of n-butane and oxygen. N-butane feed to RPLUG model is equal to 0.0075 mole fraction and 0.21 mole fraction of oxygen which is rich oxygen state. Temperature and pressure of feed streams are set at 379.85°C and 1.6 atm. Diameter for reactor is 0.0025 m and length with 1.0 m. Catalyst used in the simulation is vanadium phosphorus oxide. Simulation of Aspen model was compare with literature to validate. Sensitivity was carried out with three different condition which is temperature, pressure, and feed flow rate. In optimization, the objective function is to maximize conversion of n-butane. The optimization give optimum value which is molar flow rate n-butane in at 0.001 kmol/hr and reactor temperature at 550°C.
