Syngas production from sugar cane bagasse in a circulating fluidized bed gasifier using Aspen Plus™: Modelling and Simulation

摘要

The gasification of the sugar cane bagasse produces synthesis gas (syngas) in which CO and H_2 are the essential components. The composition of producer gas depends on the types of gasifier and the gasification conditions among others. This work is developed by using the model of biomass gasification in a circulating fiuidized bed gasifier using the ASPEN PLUS simulator. The Gibbs free energy minimization method was used to predict the composition of the produced gas. The influence of operating conditions as temperature, equivalence ratio (KR), and steam injection on gasifier performance are investigated. The model predicts syngas composition, heating values and conversion efficiency in good agreement with published experimental data.
