Nitrogen Generators How It Works

At a given pressure and membrane size, increasing the nitrogen flow allows more oxygen to remain in the gas stream, lowering nitrogen purity. Conversely, decreasing nitrogen flow increases purity. For a particular purity, higher air pressure to the membrane gives a higher nitrogen flow rate. Purity ranges of less than 90% to 99.9% are possible.

DOE Explains...Carbon Sequestration | Department of Energy

Carbon sequestration refers to the storage of carbon dioxide (CO2) after it is captured from industrial facilities and power plants or removed directly from the atmosphere. Those captured CO2 emissions are then safely transported and permanently stored in geologic formations. Storing CO2 is increasingly important because these emissions are warming the Earth''s

Nitrogen Cycle – Definition, Steps, Importance with Diagram

The series of processes by which nitrogen and its different forms are circulated and interconverted in nature with the help of living organisms is called the nitrogen cycle. It shows the path that nitrogen follows through the biogeochemical cycle using its storage reservoirs, such as the atmosphere, living organisms, and soil.

Ammonia—a renewable fuel made from sun, air, and water

But its energy density by volume is nearly double that of liquid hydrogen—its primary competitor as a green alternative fuel—and it is easier to ship and distribute. "You can store it, ship it, burn it, and convert it back into hydrogen and nitrogen," says Tim Hughes, an energy storage researcher with manufacturing giant Siemens in Oxford, U.K.
