Digital Simulation of the Steady State Behaviour of Moving Bed Processes;

A mathematical description of a complicated pellet indurating machine is presented that is simple and useful for digital computation and optimisation purposes. The arguments for some of the approximations used are given together with the resulting differential equations. A short discussion is devoted to some of the computational aspects.The verification of the model is described briefly, and typical computational results are presented from which some process conclusions are drawn.Although the process is specialised, the approach followed in this paper may be useful to other types of packed bed processes including sintering and drying of foods.
