Abstract
Flowsheeting program packages are now commonly used in chemical engineering for the design of processes involving fluids. The simulation of processes which involve solids or solids and fluids is not as advanced. In solids processing it is still common practice to design one apparatus separately from the other. There is a lack of suitable methods to combine single apparatus models to form a process and to treat this process as a whole. With the program package ‘SolidSim’, a simulation system especially designed for the simulation of processes including solids has been developed. At the present state of development, modules are available for classification, particle size reduction, crystallisation and dissolution, liquid-solid separation, gas-solid separation, agglomeration, reaction, drying, conveying and different general modules. The structure of the system is explained in detail and the application to a process for the treatment of contaminated sludge is shown.
