A flexible model for biomass fast pyrolysis in Aspen+

In order to estimate the heat of condensation of fast pyrolysis product of woody biomass a model to be used in the chemical process simulation software Aspen+ has been developed based on the composition of wood fast pyrolysis product. A simulation model for biomass fast pyrolysis was developed. The results obtained are in good accordance with values found in the literature. With more specific data (e.g. from measurements) it should be possible to adjust the flexible model to other data. A simple method for computing pyrolysis product composition (described by 22 different substances) for multiple biomass feedstock has been described as well. The method can be further developed in order to simultaneously match mass and energy balance of different BFP processes. It seems that the model is credible enough for further use of the product composition in terms of integration of the heat condensation with a combined heat and power plant. As there is no data available for condensation behavior of BFP products further evaluation is only possible once better measurement data is available
