Cryogenic grinding/milling with liquid nitrogen | Air Products
Our systems use liquid nitrogen to cool down a feed material prior to and/or during milling to either help prevent its melting or decomposition, or achieve embrittlement. While each product is unique, the major benefits of cryogenic grinding are the same: Higher yield of particles in your target range. More uniform particle size distribution.

Ionic Liquid Assisted Extraction of Nitrogen and Sulphur ...
Removal of air pollutants, such as nitrogen and sulphur containing compounds from a model oil (dodecane) was studied. An ionic liquid (1ethyl3methylimidazolium chloride [C2mim] [Cl]) was used as an extractant. Liquidliquid extraction by using 1ethyl3methylimidazolium chloride [C2mim] [Cl] was found to be a very promising method for the removal of N and Scompounds.

Tips to apply nitrogen and sulphur inseason | The Canola ...
· Nitrogen options for in crop appliion are urea (dry), UAN (liquid) or ammonium sulphate (if sulphur shortages are also expected.) UAN, being comprised of half ammonium nitrate, is slightly less prone to losses than dry urea broadcast on the surface, but both surface appliions require rain (ideally 15mm or more) soon after appliion to move the fertilizer into the soil and limit ...

Safe Handling and Utilisation of Liquid Nitrogen (LN2 SOP 19
Liquid nitrogen rapidly vaporises to gas that is approximately 700 times the liquid volume. By displacing air, the gas has the potential to kill by asphyxiation. When the oxygen concentration in air is sufficiently low, a person can become unconscious without any warning symptoms. Over Pressure Since liquid nitrogen boils rapidly, users must ensure that it is never used in a closed system ...
