Trees play an important role in producing oxygen from carbon dioxide. "A 115 year old Beech tree exposes about 200,000 leaves with a total surface to 1200 square meters. During the course of one sunny day such a tree inhales 9,400 liters of carbon dioxide to produce 12 kilograms of carbohydrate, thus liberating 9,400 liters of oxygen.
There are seven oxides of nitrogen that may be found in the ambient air. Nitrous oxide (N2O) is a greenhouse gas with significant anthropogenic sources contributing to its worldwide abundance (∼ ppm). However, nitric oxide (NO) and nitrogen dioxide (NO2) are the two principal nitrogen oxides associated with combustion sources. Ambient concentrations of these two gases vary widely ...
A carbon dioxide scrubber is a piece of equipment that absorbs carbon dioxide (CO 2).It is used to treat exhaust gases from industrial plants or from exhaled air in life support systems such as rebreathers or in spacecraft, submersible craft or airtight dioxide scrubbers are also used in controlled atmosphere (CA) storage. They have also been researched for carbon capture and ...
