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 ...
Ammonia is used in numerous different industrial applications requiring carbon or stainless steel storage vessels. Ammonia with at least 0.2% by weight water content is not corrosive to carbon steel. NH 3 carbon steel construction storage tanks with 0.2% by weight or more of water could last more than 50 years in service. [141]
Much is still unknown about the impact of ammonia pollution, but rising emission rates concern scientists. The level of ammonia in the atmosphere was more than twice as large in 2010 as it was in 1940. [8] Ammonia is now recognized by many countries as a major pollutant and some have begun taking steps to limit their emissions. [7]
The United Nations is trying to broker a resumption of Russian ammonia exports through Ukraine, a Western diplomat said on Tuesday, a move that could stabilize a landmark deal allowing Ukrainian ...

Described by the Asian Development Bank as the world's most polluted river. [30] 2,000 industries, primarily textile factories, contaminate 5,020 sq miles of the river with over 20,000 tons of waste and 340,000 tons of wastewater daily.
The industrial production of ammonium nitrate entails the acid-base reaction of ammonia with nitric acid: [12] HNO 3 + NH 3 → NH 4 NO 3. The ammonia required for this process is obtained by the Haber process from nitrogen and hydrogen. Ammonia produced by the Haber process can be oxidized to nitric acid by the Ostwald process.
