About LinkBacksChemistry is such a weak subject for me... so forgive perhaps the niavety of the question, but...
Is there no type of material that can filter out C02, or in better words, seperate C02 in a filter?

The carbon dioxide can be scrubbed by passing through a solution such as aqueous ammonia or monoethanolamine (MEA). The carbon dioxide is absorbed in the solution at low temperature then released by heating the solution. The carbon dioxide could then be pumped into subterranean storage reservoirs. The solution can be recycled indefinitely.
At present the cost of this system would be considerable. Electricity produced at plants with scrubbing capacity would be from 30% to 80% more expensive.

You can turn it into carbon monoxide, and carbon. One method is hot arcing aluminum in the presence of carbon dioxide.
Another is a mixture of carbon dioxide and oxygen passed over glowing graphite. It yields almost pure carbon monoxide.
There are a lot of ways to do it. They used some other chemical in re breathers to do it as well. Sodium Hydroxide I believe, will absorb Carbon dioxide from the air.

Then why can we not use any of these methods in a special type of filter over industrial buildings...?You can turn it into carbon monoxide, and carbon. One method is hot arcing aluminum in the presence of carbon dioxide.

You want to pump poisonous carbon monoxide into the atmosphere instead of carbon dioxide? You want to double your energy consumption to produce the filter materials?
We can do something with the carbon monoxide other then let it fly. Energy is free. But you have to have, the stomach for Benjamin Franklin. And what he discovered.

But if you wanted to collect it and make use of it, we could. But nobody really cares about it, except for some lame new scheme, or to get grant money.
It is just another scheme. To get everyone in a panic. To make it seem like the President and Senate are just stymied by the big carbon dioxide issue.
Years ago General motors boasted about all the water and carbon dioxide they were creating with all the car motors. They were so proud. Because back then we knew it was not a bad gas. Today it is monster. Ha-ha.
Tomorrow it will be the ice age. You have to keep up on these big issues. And look away from the little 1.2 Trillion give away packages, they are giving to very bad people. People that I would not even want to know.

To what end? Are you separating it out to get rid of it or to utilize it for some other purpose?

If you mean to filter it out of the atmosphere, this can be done but is impractical because of the extreme dilution of CO2 in air. The method John Galt mentions, using amines and sometimes sodium carbonate are only really effective on concentrated CO2 streams such as are found in in a refinery or gas processing plant, or the flue gas from a power plant. The captured CO2 is usually vented to the atmosphere. Some of it is sold to oil companies to inject in oil bearing formations for secondary recovery.

I don't want to be crucified in asking such questions. Ok?
Wait, you want to break up carbon dioxide, which you call 'harmless', into carbon monoxide that can then be broken down using expensive and lengthy reactions? What does this achieve?We can do something with the carbon monoxide other then let it fly. Energy is free. But you have to have, the stomach for Benjamin Franklin. And what he discovered.

I'm afraid I don't understand your response. Crucified? I gave a straightforward answer to your question, hoping you would find it helpful. That's why this board exists.I ask because chemistry is not a big subject of mine.If you mean to filter it out of the atmosphere, this can be done but is impractical because of the extreme dilution of CO2 in air.

I say let the plants have it. It is not a bad gas. But if you really wanted to get rid of carbon dioxide and I do not see why. We could do it.Wait, you want to break up carbon dioxide, which you call 'harmless', into carbon monoxide that can then be broken down using expensive and lengthy reactions?

Because there are approximately5,148,000,000,000,000,000 tons of air treat or filter. puny mankind is not going to do it.
Ocean acidification is the reason why.I say let the plants have it. It is not a bad gas. But if you really wanted to get rid of carbon dioxide and I do not see why.

I'm actually with you on the global warming front; I don't buy it.
We could do it. I have no issue about doing just about anything. But why are we going to do it? It is a great gas.
Do you know why Grumman Aero Space was afraid to send men into space on their own, as a single company?
Because most of the country was believing, and teaching wives tales to their children. Doctors could not agree upon chemical formulas. Doctors were arguing about what humans breathed in. And what they exhaled.
The Benjamin Franklin project was started, to find out exactly what humans breath or exhale to live.
Grumman did not need the high oxygen content in the space craft. Yet they were told they did need a high oxygen content, by the leading doctors and scientists of the time. Even though they had scientific proof of long durations, of men in other atmospheres.
If there was an accident, Grumman would be held responsible for going against the castle.
We had science all neatly done in the late fifties. It was over done in the fifties.
It was too scary for slimy politicians. The politicians used the excuse violent minority types. To introduce a lesser education to American students. To keep the secret of the atom, the building block of the universe. From "violent minority types".
There has not been any real science since the late sixties. And even then real science only popped its head up, for a breath of air. It immediately came under attack.

Why do divers die if they run low on oxygen during a dive, then, if a high oxygen percentage (22%) is not required?
How long is Chemboy going to let the Wild Willy show go on? Just send his crap straight to trash can and be done with it. Furthermore look a all the space wasted on this loon, it would be better if forum members just ignored his drivel and quit trying to reason with a stump. I sent a PM to Chemboy awhile back with no reply so I'm taking it to the forum enough is enough. opinion is for politics and religion,science deals in facts.
I do not believe they run low on oxygen, as they go deep the body actually starts to absorb to much oxygen. As they come up, the oxygen is released.
That is why really deep subs use helium. They do not want the nitrogen or the oxygen to be in the blood. As you take the pressure off the body both gases are let loose. My money is on the oxygen being the killer.
They basically run out of a gas to cleanse the lungs.

Did you ever try to discuss any point you do not agree with using, precise accounts of your life. And what you have learned in chemistry?
A blanket attack against everything I said will prove at least somewhat wrong.
