Nitrogen nutrition in plants is a key determinant in crop productivity. The availability of nitrogen nutrients in the soil, both inorganic (nitrate and ammonium) and organic (urea and free amino acids), highly …

To keep capital costs competitive, membrane systems are usually quoted using a 150-200+ PSI air compressor, because a membrane will produce more nitrogen flow at a given purity at higher pressures. Membrane technology is generally used when purities required are 99% or lower and some are not efficient at that purity.

The availability of nitrogen nutrients in the soil, both inorganic (nitrate and ammonium) and organic (urea and free amino acids), highly differs and influences plant physiology, growth ...

OsNRT1.1B has also been shown to be involved in regulating the root microbiota to facilitate organic nitrogen mineralization in soil, thus mediating plant-microbe interactions. Furthermore, the divergent functions of OsNRT1.1A and OsNRT1.1B in regulating nitrogen use in rice suggest that the function of NRT1.1 is still far from fully …

Similar to membrane plants, PSA systems require an over-proportional air demand with increasing nitrogen purity. Consequently, the operation of high-purity PSA plants motivates a particular interest in process optimisation with a focus on the reduction of air demand; however, without increasing the number or volume of adsorber columns.

Industrial processes for chemical separation, including natural gas purification and the production of oxygen and nitrogen for medical or industrial uses, are responsible for about 15 percent of energy use worldwide. Researchers at MIT and Stanford developed a membrane to carry out separation processes with roughly 1/10 the energy …

Nitrogen is a non-flammable air gas that forms 78% of the earth's atmosphere. Valued for its inert properties in its gaseous form, nitrogen displaces air and therefore, reduces or eliminates the oxidation of materials. It is also used as an assist gas for laser cutting. Given the extremely low temperatures of its liquid state, nitrogen is an ...

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.
