I'm working on a project on landfill sited biogas plants.I'm studying about Benfield's absorption method of CO2 and I can't find anything on the web related to the facilities or units that a CO2 removal plant, consists of.
What I mostly need is something like a flow diagram of the plant.
Please, if anyone knows anything about this would help me. Anything related to the above is welcome! Thanks....

OK, I'm sorry about that....

Hi,
I worked in Monoethylene-Glycol plant where we used Benfill solution for removal of carbondooxide so I have detail knowledge about which infiormation do you want,pl contact on my email address.Also introduce yourself.

akz,

You can find information about Benfield process on the licensor website:
http://www.uop.com/o...eld_process.pdf
Go around a little bit UOP's website, there is more than these two pages.
Anyways my humble opinion is that Benfield process will not work in your case, or it will be extremely expensive. Benfield process requires a high inlet gas pressure, while at a landfill biogas generator I would expect to have pressures close to atmosphere.
So, you will have two options:
1. Compress your gas at the required pressure for Benfield to work, still viable when your CO2 composition is fairly low;
2. Focus on other CO2 processes that work at near atmospheric pressures, MEA for instance.

Thank you very much for helping me Andrei! I do have some doubts about this method myself but I was asked to use this one in my project, so I can do nothing...
