Simulation of Biomass Gasification in Fluidized Bed Using Aspen Plus
Gasification is a thermo-chemical process to convert carbon-based compounds such as biomass and coal into a gaseous fuel. Among the various types of gasification methods, fluidized bed gasification is one which is considered as more efficient method than others as biomass is fluidized in a mixture of air/oxygen and steam. In the present study, a comprehensive steady state process model has been...

متن کاملBiomass Gasification-Based Biorefineries in Pulp and Paper Mills – Greenhouse Gas Emission Implications and Economic Performance
The pulp and paper industry has a great opportunity to take advantage of the experience about forestry and wood handling for production of renewable fuels, chemicals and materials. Residues from forestry, i.e., tops, branches and stubs, have great potential to become a raw material that can replace crude oil or natural gas in many applications. By constructing a gasification-based production fa...
متن کاملTwo Phase Modeling of Char Combustion in a Circulating Fluidized Bed Reactor Using ASPEN PLUS
In this paper, combustion of char in the riser of circulating fluidized bed was modeled using ASPEN PLUS. Since physical and chemical phenomena are involved in the process, the model integrates the two-phase hydrodynamic sub-model with the reaction sub-model derived from the literature. In the proposed model, the fluidized bed is divided into several sections and the behavior of each section wa...
متن کاملEconomic Potential of Biomass Based Fuels for Greenhouse Gas Emission Mitigation
Use of biofuels diminishes fossil fuel combustion, thereby also reducing net greenhouse gas emissions. However, subsidies are needed to make agricultural biofuel production economically feasible. To explore the economic potential of biofuels in a greenhouse gas mitigation market, we incorporate data on production and biofuel processing for the designated energy crops—switchgrass, hybrid poplar,...
