Summary
PARSIM, a one-dimensional simulation tool for dynamic reactions in porous particles is presented. Several features are included in the package (Dusty-Gas-Model, sorption effects, evaporation, condensation, diffusion through a product layer, pore models,…). As an example the drying process of a solid wood particle is simulated and results are presented. The discretization of the space derivatives is achieved by the method of Orhogonal Colloction on Finite Elements which proved to give higher accuracy compared to the method of Finite Differences which is optionally provide by PARSIM. LIMEX is used as integrator in time direction. Even complex reaction systems (pyrolysis, desulphurization,…) can be simulated easily by PARSIM.
