Urea and nitrogen stabilizer compositions and methods and systems of making and using thereof

摘要

This invention relates to an improved urea-nitrogen stabilizer composition and methods, systems and apparatti for making thereof. The nitrogen stabilizer composition is incorporated into molten urea to result in a composition that contains less biuret, NMP, nitrogen stabilizer and/or impurities and provides an effective solid fertilizer. These compositions are useful in odor control.

主权项

1. A method of producing a solid urea-nitrogen stabilizer composition comprising:
a) forming molten urea; b) adding a nitrogen stabilizer composition to said molten urea, wherein said nitrogen stabilizer composition comprises NBPT at a purity of at least 95% by weight; and c) cooling the molten urea-nitrogen stabilizer composition to form the solid urea-nitrogen stabilizer composition.
