Household 'ammonia' is a solution of NH 3 in water, and is used as a general purpose cleaner for many surfaces. Because ammonia results in a relatively streak-free shine, one of its most common uses is to clean glass, porcelain, and stainless steel. It is also frequently used for cleaning ovens and for soaking items to loosen baked-on grime.
Airgas, an Air Liquide company, is an American supplier of industrial, medical and specialty gases (delivered in packaged or cylinder form), as well as hardgoods and related products; one of the largest U.S. suppliers of safety products; and a leading U.S. supplier of ammonia products and process chemicals.
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.

In 1993, ammonia unit AM 76 was fully automated by Honeywell, and again in late 2015. [28] In 2001, the European Bank for Reconstruction and Development approved a loan for $40 million for expansion of ammonia production. [29] Liquid ammonia – TogliattiAzot's total output of liquid ammonia in 2014 was 2.9 million tons. [30]
About 14,000 pounds of ammonia, which was used as a refrigerant at the frozen vegetable warehouse, was lost in the fire, the Washington Department of Ecology confirmed Tuesday to the Tri-City Herald.
Ammonia electrolysis may require much less thermodynamic energy than water electrolysis (only 0.06 V in alkaline media). [25] Another option for recovering ammonia from wastewater is to use the mechanics of the ammonia-water thermal absorption cycle. [26] [27] Ammonia can thus be recovered either as a liquid or as ammonium hydroxide. The ...
The ammonium ion is mildly acidic, reacting with Brønsted bases to return to the uncharged ammonia molecule: [NH 4] + + B − → HB + NH 3. Thus, the treatment of concentrated solutions of ammonium salts with a strong base gives ammonia. When ammonia is dissolved in water, a tiny amount of it converts to ammonium ions: H 2 O + NH 3 ⇌ OH − ...
