Hi All,

Need to design a gas adsorption column for a pilot plant.The adsorbent is activated carbon & adsorbate is natural gas.

The pressure of the column will be varying from 0.1Mpa - 4Mpa.

Would be very grateful if you can send me some design tips / any references regarding to the gas adsorption column design.

Thanks,
Bhagya

Bhagya,

Take a look at these documents .
Hope this helps

Bhagya,
Could you share more details on this project?
What do you mean with "The pressure of the column will be varying from 0.1Mpa - 4Mpa"?
Which are the contaminants to be removed from the natural gas stream?
Are you thinking about a once-thru plant or a TSA or VSA or PSA scheme?
What is the flow you're going to consider?
Other......

Hi Breizh,

Thanks lot for the documents. it was useful.

Hi gegio

Yes, This is not a contaminant removal unit but the gas adsorption unit for methane storage.
The purpose of the design is to store bio gas in activated carbon bed.
As per the literature, the activated carbon will be adsorbed methane during the pressure from 0.1MPa to 4MPa.
Hence the unit need to be develop to that range.

Ya, this is a kind of PSA system. Here I need to store the producing bio gas from the reactor in a adsorption column.
Hope to supply the produced bio gas to the adsorption column till it pressurized to 4MPa. Since this pressure is high in value, thinking that the Freundlich Adsorption Isotherm is unable to use for the design calculations.

Do you have any experience relating to design these kind of units? Would be great if you have any suggestions regarding to this.

Thanks

Bhagya

Bhagya,
thank you for the clarifications.
Sorry to say that I'm not able to help you since this is not a "standard" industrial application of adsorption.
