Here, we introduce our software to simulate the dynamic behaviour of fixed bed adsorber and zeolite membrane processes. On top of the executables, we are currently developing a windows interface. Both executable are capable of computing dynamic transients, steady-states, and performing parameter studies based on a Newton-Euler continuation method. Major attention was put on the development of a computationally cheap code for evaluating the thermodynamic correction factor when the Ideal Adsorbed Solution (IAS) or Real Adsorbed Solution (RAS) theory is used. Therefore, adsorption processes based on the IAS- (or RAS-) theory can be simulated in a reasonable time span.
