I have some doubts with simulating Water gas shift reaction for Ammonia production using Aspen Plus. 

Following is the given feed conditions. 

 

CO = 7.5 mol/s

H2 = 37.5 mol /s

CO2 = 4.95 mol/s

 

1. What type of reactor should I select ? I referred many literature's but unfortunately didn't find any consistency among the 3 common (R-EQUIL, RGIBBS and RPLUG.) reactors.

 

2. For High temperature I am using the inlet temperature of 350 deg c and outlet temperature of around 450 deg. c. I couldn't find the pressure mentioned anywhere.

 

3. While running simulation after defining feed composition, the sensitivity analysis (varying temperature of the reactor from 300 to 600 deg. C) shows an increase in reactants (CO & H2O) instead of products (CO2 & H2). I believe it is because backward reaction is favored, due to high concentration of products. 

 

I am stuck with this problems for quite few days now. Any help would be appreciated.

Hi,

I am working on CO2 reduction to methanol,

could you share some idea or your model on how to do the aspen plus simulation
