Hello Everyone........I have to simulate Autothermal Reformer to maximize CO concentration with CO2 recycle....can anyone help me with this as I am completely new to Aspen. Is it easier to learn Hysys from Aspen One V8.0 or 7.1? Please reply soon.... Also provide me the link for the latest AspenOne Version. Thanx in advance

Some Details Regarding ATR:
1. Reaction taken from following paper:

[link Point to another website Only the registered members can access] 2. Conversion of methane> 90%.
3. What to find:
1. CO2/ CH4 Inlet molar ratio vs pressure for different Steam/ Methane ratio.
2. Temp vs Pressure at different Steam/ Methane ratio.
3. CO2 Out Moles Vs Pressure at different Steam/ Methane ratio.
4. CO2+Steam/CH4 Ratio vs Pressure at different Steam/ Methane ratio.
