Numerical Methods for Simulation of Chemical Engineering Processes. Essential fundamentals and the current state of the art in simulating the dynamic and the steady state behaviour of chemical engineering processes are discussed. It is shown that discretization of the spatial derivatives in the balance equations leads to a system of so‐called DAE (differential algebraic equations), consisting of ordinary differential equations in time and algebraic equations. The paper discusses necessary steps to solve the DAE and mentions approved standard software for these steps as well as for the solution of the DAE as a whole.
