thanks a lot! the amine stuff seems too complex and expensive for this home experiment seems if you have (let's say) smoke with 15% of CO2 from a boiler of 70kgs of combustible (10,5 kgs of CO2 in total), being expulsed in 24 hours, (this is 0,4375kg/hour = 7,3grs/minute), then I may need at least 3 times that weight on soda lime (31,5 kgs) to absorb it, isn't it too bad rate of absortion? regarding soda lime recycling, do you think it would be the same process than for glasses but considering it has CO2 should differ I guess why are you doing this? I am doing a small research to find "feasible methods for separating CO2", this is a topic I have been assigned in my class

very interesting John, now I have something to research I want to absorb the CO2 of steam boiler for 48 hours, which rate % of absortion do you expect? and how much kgs of soda lime will be needed? how to recycle soda lime? btw why do you like signatures THAT much? thanks

Dear John, (for now) I need to find a method to separate CO2 from pollutant air, I have found many expensive, advanced and (ofc patented!) ways: membranes, materials, laser, CaO... not feasible Having a tank at 5ºC and 40 bar to keep CO2 could be feasible but I think it may need a lot of energy, if this energy is stop then the tank may expode since CO2 is turn into gas again In other words, what I need is a cheap and feasible method (not patented) for taking CO2 from pollutant air

there is another issue, the storage in liquid state, I may need a sensor into the very high pressure tank to cool it up to keep it liquid:

Thanks guys, this is what I plan to do: - 1st device makes condensation of pollutant air cooling up to 1ºC aprox, so H2O is liquified and this is expulsed out of the system (not needed for analysis) (consider aprox. 1,5grs of air is present per 1gr of gasoline after combustion) - 2nd device takes the resulting gas without water and cool it up to -80ºC (point for CO2) and this liquid is stored the rest of gases are expulsed since this study will consider only CO2 (for now) There are many aspects to point out: pumps, filters, other gases affected by this, devices, continuously air issues, pressure... but, briefly, does it make sense guys? thanks in advance

hi there, name's Ann, want to learn about how to make pollutant gas into liquid cheers!

hi there I am new! I am doing an experiment to obtain pure liquid from smoke gas from: steam boiler vs car exhaust without gass loss, then will send to a lab to analyze its CO2 and other parameters, questions: - is this liquefaction experiment possible? (do I need to cool-up smoke before and how? is this smoke liquified-able...) - which industrial device(s) to use? (cheap and small if possible, consider must absorb smoke continuously...) Thanks in advance
