THE SPATIAL REACTION ENGINEERING APPROACH (S-REA) AS EFFECTIVE MULTIPHASE DRYING APPROACH TO MODEL THE HEAT TREATMENT OF WOOD UNDER CONSTANT HEATING RATE
Wood may contain several harmful chemicals which can be removed by high-temperature treatment.This is essentially a drying process under linearly-increased gas temperature up to final temperature of 220-230 oC which is a challenging process to model.The effective model is useful in process design,evaluation of equipment performance and troubleshooting.In this study,the S-REA (spatial reaction engineering approach) is used to model the heat treatment of wood under constant heating rate.The REA (reaction engineering approach) is implemented to describe the local evaporation/condensation rate and combined with a system of equations of conservation.A good agreement between the predicted and experimental data is observed.The S-REA is accurate to model the heat treatment of wood under constant heating rate.For all cases investigated,the process seems to be independent on the liquid diffusion.The application of the S-REA gives better understanding of transport phenomena during the heat treatment.It is argued here that the S-REA is an effective non-equilibrium multiphase approach to model the heat treatment of wood.
