I have a liquid flow with entrapped CO2, we are trying to remove from the liquid stream the maximum amount of CO2 using Nitrogen as the stripping gas.

 

I'm having trouble to do it in Aspen Plus or Hysys since they dont have a unit operation for a co-current flow.

 

There isn't a reaction in the column. We want to be able to optimise the amoun of injected nitrogen into the liquid stream.

 

Any ideas on how to simulate this?

 

Regards and thanks in advance for all your help

What else in in the liquid with the CO2? If there is water, it will be an electrolytic process. In that case, you want to use an electrolytic model like ProMax.

Hi RockDock

 

Basically is water.... with some methane, ethane, oxygen, nitrogen and CO2.

 

I will try to have a look at ProMax.

 

Thanks
