Dear colleagues,
Recently, I need to test the CO2 capture efficiency of a material. However, my experience in this is zero. I can imagine the basic setup which is a system with a mixing chamber connecting to an absorption column and an analyzer. However, I still have some unknowns listed below:
1. What is the common ratio of CO2 and inert gas in the mixing chamber?
2. What is the common rate for gaseous mixture when operating the systems?
3. Which instrument can be used as CO2 analyzer?
Thank you so much in advance.
Just have a look at papers with experimental data for solvent-H2O-CO2. The part with experimental set-up should present details for what you search for. Start from these:
- 10.1016/j.ces.2011.08.042
- 10.1016/j.ces.2011.02.033
- 10.1016/j.ces.2009.12.024
- 10.1016/j.fluid.2011.08.017
First of all you should define the purpose of the co2 removal. Is it direct air capture (420 ppm CO2) or is ist classical CO2 capture from a flue gas? This answers question 1 and hepls you to find suitable instruments for question 3. Then you define the gas load of your column according to the design rules. You should pay attention to achieve a propper gas.load which is mainly dependent on the column diameter (you did not mentiont hat).
