CO2 Absorption

manowars · April 12, 2014, 04:39

Hi,

I am trying to simulate the CO2 absorption collumn by following Reaction:
CO2 + NaOH -> Na2CO3 + H2O

I setup the transient solver with multiphase Eulerian (2 phases), plus species transport:
- Gas phase: CO2
- Liquid phase: Mixture (NaOH, Na2CO3, H2O)

I did same procedure with tutorial of coal combustion.

However, when I show the contour plot of molar concentration of Na2CO3 (product), all domains are zero -> it means the Na2CO3 was not produced? I dont know why it's so strange. Can anyone help me? Thanks,

Maybe the source term or the reaction haven't been defined correctly
