A substance so easy to get, as baking soda, might be the answer to cleaning the air of CO2 emissions.
A team of researchers have found a way to eliminate the carbon dioxide from the atmosphere with the help of baking soda. Scientists developed some microcapsules made of a polymer shell that is highly permeable and a fluid consisting of sodium carbonate solution to take out the carbon dioxide from coal and natural gas eliminated by power plants.
This process has been the first demonstration of this type, to capture CO2 in a controlled way and its release could be possibly used for industrial purposes like in the production of steel and cement.
Engineers from the Lawrence Livermore National Laboratory, worked in collaboration with the scientists from the University of Illinois and Harvard to create a media capture of carbon which contained core-shell microcapsules.
According to statements of the laboratory, the capture of carbon was aimed to prevent the discharge of big quantities of carbon dioxide, a greenhouse gas that captures heat and heats up the planet, into the atmosphere coming from fossil fuel used in power generators and for other industrial uses.
Even though the presently used methods turned out to be successful, they could be harmful for the environment. The main desire of the research team was to find a solution that allowed them to move away from using caustic fluids, like mono ethanol amine, to catch carbon dioxide and use less harmful substances, such as carbonates. The use of baking soda as an active chemical was an essential development, explained researcher Roger Aines from Lawrence Livermore. He added that corrosiveness worked at improved levels as the chemical compound was more benign and was always incapsulated.
Placing the carbonate substance inside the capsules would allow to be used for catching carbon dioxide without directly touching the surface of equipment from the power plant. Also, they would be able to transport it easily between absorption and release towers, even if it would have absorbed so much carbon dioxide that it turned solid.
The research for the encapsulating operation was funded by the U.S. government by the department of Advanced Research Projects Agency-Energy. Roger Aines, declared that baking soda would never loose its properties in the same way that the present technology, amine was. Baking soda, could be reused forever, while amines corrupt on the occurs of months to years, added Aines.
