yes, just like a huge air-conditioner. all industrial gas plants do just that. the process to make liquid oxygen and nitrogen plus the bottled gasses used for testing and welding come from air that has been cooled down to liquid. that liquid is allowed to warm slightly and the gasses are separated at their specific boiling point. this works good for nitrogen and oxygen which make up most of the air. CO2 is such a small percentage of air that it becomes impractical to process air just for the CO2 content. The better approach is to prevent excessive CO2 from being generated in the first place. Also the plant takes a lot of energy to do this and the electric grid would probably make more CO2 in supplying the power than CO2 could be extracted by this method.

Sure, they do it on the space shuttle all the time. They are called "air-scrubbers" and use a chemical process to extract carbon-dioxide from the air. The problem is it would have to be massive to have any effect here on earth, and also that the concentrations are still relatively low compared to that in a small closed volume, like the space shuttle, and would not work very fast.

Trees is the obvious answer.
As far as current technology goes, there are amine scrubbers used to remove CO2 from natural gas and other materials. In theory you could create a huge one to run atmosphere through, but it would require huge amounts of energy and huge amounts of amine. Then you run into the really big problem. What do you do with the CO2 after you've removed it from the atmosphere? You have to put it somewhere.

the least puzzling way could be to bubble the air by way of lime water. The CO2 reacts to type a precipitate of calcium carbonate, leaving CO2 unfastened air because it exits. you additionally can blow the air in the time of stable lime, yet you will possibly might desire to recirculate it lots to get the reaction to bypass to ending touch. via lime I propose calcium hydroxide, Ca(OH)2 to unencumber the oxygen from calcium carbonate, first react it with HCL to type organic CO2. Then warmth the CO2 over a catalyst of iron doped zeolite and hydrogen to offer water and ethylene. A nonthermal plasma utilized to ethylene will generate carbon soot and get well the hydrogen. Electrolysis of water provides back the extra beneficial hydrogen and produces oxygen. it incredibly is all there is to it. No filters in touch!

Carbon dioxide is present in the atmosphere all over the world at a concentration of less than one percent. Although the percentage is small, there is a lot of atmosphere, so there are millions of tons of atmospheric carbondioxide. As far as I know, there is no mechanism that will remove that carbon dioxide in significant quantities.

The are working on designing and building large air filters using sodium-hydroxide to absorb co2 out of the air. Personally I think it would be more cost effect to filter out the co2 at the biggest sources like power plants where the co2 is more concentrated and easier to absorb. It was estimated they would need about 500,000 industrial windmill sized filters to reduce the effects of global warming

Why would we want to do that? All plants depend on CO2 for respiration.

probably....i wouldnt doubt it......yeah, they should build something that converts co2 in oxygen.......i bet it would be expensive....
