Hi there, I am trying to create a dynamic model of a pressure swing adsorption process (PSA) to purify hydrogen with a transient feed. I have read about dynamic modeling and simulation with DWSIM which sounded very helpful. in the Users guide i see in Part V that an example of an application with of the dynamic model is 'design of inherently dynamic continuous processes – for example, pressure swing adsorption' However under the object palete for the flowsheet in only see options for 'compund separator'...
