Thermo Chemical Equilibrium Modelling of a Biomass Gasifying Process Using ASPEN PLUS
This article deals with the use of ASPEN PLUS to model the thermo chemical processes occurring in wood biomass gasifiers. An original equilibrium gasification model using ASPEN PLUS was first built and validate based on existing data of a downdraft gasifier (DDG). The thermo chemical models assume that reactants reach chemical equilibrium. The simulations enabled to predict the composition of the flaming pyrolysis gas as well as the final composition of the producer gas. A parametric study based on air/fuel ratio variation was then conducted. The model was finally adapted to the operating conditions of a staged gasifier developed at the Technical University of Denmark (DTU). Parametric studies were conducted to observe the effect of humidity with a low air injection. ASPEN PLUS was shown to be well adapted to model the gasification process (equilibrium), and it was possible to simulate both a DDG and a DTU using the same model. Data about the composition of flaming pyrolysis and the exit gas were obtained.
