| Abstract | Utilization of biomass as energy source by gasification is preferred because it uses relatively low amounts of oxygen as compared to combustion; also, the synthesis gas produced is at a higher temperature than flue gas. Biomass as a feed can constantly change since its source can vary from time to time, a fluidized bed reactor should be used in order to have the flexibility of handling different feeds. The objective of the work presented in this paper is to model a biomass gasification process in ASPEN Plus. This was done by splitting the gasification process into five different sub processes, starting with pyrolysis or decomposition of the feed, volatile and non-volatile component separation, volatile reactions, char gasification and finally solid gas separation. The reaction kinetics of the model, boiled down to two first order differential equations, one for conversion through combustion and the second for conversion through steam gasification. These were solved in MATLAB using the reaction kinetic constants provided by Nikoo et al. Overall, the APSEN Simulation designed in this work can be used as a tool to test other biomass feeds for a gasification process by simply changing the feed composition and flow rates of biomass, steam and air. |
