Simulation and optimization of bio-hydrogen reactor using aspen plus

Simulation and optimization of bio-hydrogen reactor using aspen plus / Ahmad Fuzamy Mohd Abd Fatah
Proses gas bio-hidrogen menggunakan kaedah pengegasan air supergenting telah dianalisa dalam bentuk bilangan gas hidrogen dan pengeluaran gas karbon monoksida. Reka bentuk tangki reactor yang telah dicadangkan dalam simulasi ini melibatkan beberapa jenis substrat iaitu gliserol dan phinol. Gliserol dan phinol kemudianya disimulasikan menggunakan AspenPlusTM versi 8.8 mengunakan kaedah Peng-Robinson. Pelbagai pengaruh dalam setiap parameter telah diuji untuk mendapatkan keputusan yang paling terbaik. Parameter-parameter yang terlibat dalam simulasi ini ialah jenis-jenis substrat, peratusan substrat yang digunakan, haba dan tekanan. Sebanyak 20 peratus substrat telah dipilih dan simulasi telah dijalankan terhadap glycerol dan phenol. Keputusan menunjukan bahawa haba yang tinngi dan tekanan yang rendah diperlukan untuk mendapatkan bacaan gas hidrogen yang terbaik. Oleh sebab itu, beberapa syarat telah diuji terhadap simulasi ini. Kos analisis juga telah ditunjukan dalam simulasi ini untuk menilai sama ada hidrogen atau methane mempengaruhi kos pengeluaran dalam sesebuah kilang pemerosesan hidrogen. Akhirnya, perbandingan diantara jenis-jenis substrat telah diuji untuk mengetahui substrat yang mampu memberikan bacaan gas hidrogen yang maksima. _______________________________________________________________________________________________________ Production of bio hydrogen via supercritical water gasification (SCWG) is analyzed in term of hydrogen production and carbon monoxide release. The design of the reactor proposed in the supercritical water gasification process involving several substrates which are glycerol and phenol. Both of the substrate is simulated through AspenPlusTM version 8.8 using Peng-Robinson method. The influence of various parameter has been test in order to achieve the best result. The parameter involve in this simulation are type of substrate, percentage of substrate use, temperature and pressure are analyzed. The 20% reactant substrate has been chosen and simulation has been run by each substrate. Result shows that the hydrogen maximum production at high temperature and low pressure without any other constraint. Thus, various constraint has been tested in order to get the best result for the simulation. The parameter has been taken for each constrain. Cost analysis also has been run in this simulation to see whether the hydrogen or methane gives the best cost value for the plant. Finally, a comparison between the substrate has been tested to determine which substrate gives better hydrogen production.
