Simulation by John Edwards, senior consultant, P & I Design Ltd.

John Edwards is a consultant engineer at P & I Design Ltd., Stockon-on-Tees, England, a consulting firm that specializes in process engineering and instrumentation. He spent ten years at operating and control companies in the U.S. and U.K. before founding the firm in 1978. He is responsible for process modeling/simulation and online optimization as well as training simulator and process software developments. He gives seminars on topics related to simulation such as the selection of thermodynamic methods.

How can I model adsoption in HYSIS or ASPEN+?
I was modeling the dehydration of natural gas with a propane cycle using HYSIS. Now I want to try with an adsorption bed (like silica). How can I model this way in HYSIS or ASPEN+?

What is the criteria for selecting a thermodynamic model?
How we can select a thermodynamic model in the batch processes simulators like Chemcad, Super Pro Designer, Aspen Batch Plus, Proism, or any other?

OTS Process
I want to know how the Project Process Engineer can help to acquire OTS, considering that the project is already approved and the supplier is almost selected. Does he need to do a simulation of the plant? Does he need to know what the common failures in the process plant are? Does he need to compile all process data; data sheet, P&IDs, PFD, etc? If you can give an idea from where I can start to develop this project, it would be appreciated.

Azeotrope simulator
I'm using a simulator in classes. How do I get the models to show me an azeotrope? Even for Water and Ethanol I don't see the azeotrope. Is there some setting I don't know about?
