Challenges and Opportunities of Modeling Biomass Gasification in Aspen Plus: A  Review

Aspen Plus has become one of the most common process simulation tools for both academia and industrial applications. In the last decade, the number of the papers on Aspen Plus modeling of biomass gasification has significantly increased. This review focuses on recent developments and studies on modeling biomass gasification in Aspen Plus including key aspects such as tar formation and model validation. Accordingly, challenges in modeling due to specific assumptions and limitations will be highlighted to provide a useful basis for researchers and end‐users for further process modeling of biomass gasification in Aspen Plus. Different computational tools are employed to investigate biomass gasification since process optimization is a difficult task and any change in parameters may affect the syngas composition due to the complex nature of gasification. Studies on modeling biomass gasification using Aspen Plus based on equilibrium and kinetic approaches from the aspects of tar formation, model validation, and fuel flexibility are reviewed.
