Technology for directly capturing CO2 from the air
Thread Content
I would like to ask everyone: Are there any technologies for directly capturing CO2 from the air that are currently in industrial use? I want to keep an eye on the technology in this area.
Industrial exhaust and boiler exhaust have such high CO2 concentrations that capturing it is difficult; don’t even think about capturing it from the air for now
Our company produces carbon dioxide; just drive over to pick it up in liquid form
It seems that there is no industrial application in the domestic market yet. It exists abroad; see: 【Hai Chuan – Lessons from Other Places】Turning Carbon Dioxide into Wealth https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=2285314 (Source: Hua Hai Chuan Liu – Hai Chuan Network)
I’ve heard that carbon dioxide is adsorbed using ion exchange technology and then collected; it seems there’s some validation regarding the efficiency rate
Your reply is just as simple and blunt as your name, hahahahaha
Calcium carbonate makes up over 95% of the composition of shells, and its content remains relatively stable; shellfish farming could thus be a potential solution for carbon sequestration. .
The CO2 concentration in the atmosphere is approximately 0.03–0.04% (V), and it is primarily generated by the combustion of carbon-containing substances and the metabolic processes of animals. Technologies for directly capturing CO2 from the air are indeed millions of times more difficult than obtaining CO2 from gasification decarburization gases and flue gases, and they require much more investment. Even as a long-term technical reserve, it will be of no use once fossil fuels such as coal and oil are depleted.
The low-pressure PSA carbon dioxide capture technology is already mature, and it can be explored if necessary.
There seems to be a paper on measuring the CO2 emitted through respiration during the growth cycle of shellfish, as well as the amount of carbon fixed in their shells; you might want to take a look if you’re interested.
