Hello all,

         I have to design a new plant with PSA type adsorber system to remove CO2,Moisture content.

          Feed condition:

               Air flow-2000Nm3/hr

               Pressure-9 bara

               Temperature-40 degc

               CO2-400ppm

               Moisture-100% RH

 

       Desired Outlet condition:

                 CO2-<1PPM

              Moisture-(-)100degc dew point @ atm. pressure     

    

   Can anybody help me in designing the system?

  Specially:

  1.How to do depressurization line size?

  2.How to determine purge flow rate?

  3.We intend to depressurize the bed upto 0.3 barg(based on purge gas pressure).Is that assumption good enough?

 

  Any reply will be highly appreciated.

Regards,

  Arpan

You seem to be missing one critical characteristic: The adsorbent isotherm / capacity

I would like to have suggestions regarding Adsorbent type also..Normally for TSA plants we use alumina for moisture removal & molsieve for CO2 removal...
