Abstract

Among the several types of gasification methods, fluidized bed gasification process has been applied as a key merit technology to ensure the product gas with high quality. Therefore, the aim of this study is to explore a novel steady state simulation approach of Imbat coal in a circulating fluidized bed gasifier by using Aspen Plus model which is based on the minimization of the Gibbs free energy of the system. The syngas composition was obtained for different operating parameters such as temperature, pressure and feed stock & steam rate to evaluate performance of the developed ASPEN Plus model. The simulation results show that the product gas produced during the steam gasification has much higher hydrogen contents than oxygen gasification models from the literature. Moreover, it is expected that the established model can be used for other type feedstocks to estimate the composition of product gas at optimized operating condition.
