Liquefaction from pollutant smoke?

[annlee]

hello there

I am doing a home experiment to obtain pure liquid from smoke gas from: steam boiler vs car exhaust without gas loss, then will send to a lab to analyze its CO2 and others, I got a couple of 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...)


Thank you guys

?? You do know that people just measure the gas directly, right? That's what the guy at the smog test place does every few years.

Liquefaction of CO2 requires cooling to -80C or so. Most of the other gases in air will need to cooled to below 77K

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!

Thanks for the answer,

yes, I know, but do point of my experiment is to measure it liquified

so I think I need kind of industrial chamber(s) and possibly other device(s), anyone help?

OK, so, as I said, you'll need to a way to get to the boiling point of at least CO2; if you want to liquefy everything, you'll need something that gets down to liquid nitrogen.

However, a much bigger problem is keeping everything liquid, which will require cryogenic storage containers, AND something that will active cool the liquids. This is not something that is easily, done in a commercial situation, much less a "home experiment."
