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.
Liquid ammonia has a very high standard enthalpy change of vapourization (23.5 kJ/mol; [28] for comparison, water's is 40.65 kJ/mol, methane 8.19 kJ/mol and phosphine 14.6 kJ/mol) and can be transported in pressurized or refrigerated vessels; however, at standard temperature and pressure liquid anhydrous ammonia will vaporize.

Hose barb fittings are small curved, bent or T-shaped pipes, hoses or tubes with hose barbs on at least one side used to join two or more pieces of piping (hosing, tubing) together. [1] Hose barbs are commonly used in the agriculture industry to connect anhydrous ammonia (NH 3) hoses. [2]
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
Anhydrous ammonia can be stored as a liquid at approximately 10 bar in steel tanks. It is classified as an inhalation hazard , but it can be safely stored and handled if well-developed codes and standards are followed.

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).
Anhydrous ammonia “is essentially pure (over 99 percent) ammonia,” says the Occupational Safety and Health Administration (OSHA). Ammonia used in households is a diluted water solution that ...
