The table above gives properties of the vapor–liquid equilibrium of anhydrous ammonia at various temperatures. The second column is vapor pressure in kPa. The third column is the density of the liquid phase. The fourth column is the density of the vapor.
As of 2018, the Haber process produces 230 million tonnes of anhydrous ammonia per year. [69] The ammonia is used mainly as a nitrogen fertilizer as ammonia itself, in the form of ammonium nitrate, and as urea. The Haber process consumes 3–5% of the world's natural gas production (around 1–2% of the world's energy supply).
Now, they’re itching to apply the anhydrous ammonia this winter. Longtime Illini FS Agronomist Howard Brown talked to Stu Ellis for From the Farm, […] From the Farm: Applying anhydrous ammonia
Ammonia electrolysis may require much less thermodynamic energy than water electrolysis (only 0.06 V in alkaline media). [23] Another option for recovering ammonia from wastewater is to use the mechanics of the ammonia-water thermal absorption cycle. [24] [25] Ammonia can thus be recovered either as a liquid or as ammonium hydroxide. The ...
Anti-meth sign on tank of anhydrous ammonia, Otley, Iowa. Anhydrous ammonia is a common farm fertiliser that is also a critical ingredient in making methamphetamine. In 2005, Iowa used grant money to provide thousands of locks to prevent criminals from gaining access to the tanks. [122] Ammonia, as the vapour released by smelling salts, has found

For fertilizer use, granules are preferred over prills because of their narrower particle size distribution, which is an advantage for mechanical application. Urea is usually spread at rates of between 40 and 300 kg/ha (35 to 270 lbs/acre) but rates vary. Smaller applications incur lower losses due to leaching.
Several nitrogen-bearing reductants are used in SCR applications including anhydrous ammonia, aqueous ammonia or dissolved urea. All those three reductants are widely available in large quantities. Anhydrous ammonia can be stored as a liquid at approximately 10 bar in steel tanks.
