    en.wikipedia.org/wiki/Anhydrous

    To clarify that it is the gaseous form that is being referred to, the term anhydrous is prefixed to the name of the substance: Gaseous ammonia is generally referred to as anhydrous ammonia, to distinguish it from its solution in water, household ammonia solution, also known as ammonium hydroxide.

  4. Haber process - Wikipedia

    en.wikipedia.org/wiki/Haber_process

    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).

    en.wikipedia.org/wiki/Ammonia_solution

    Ammonia solution, also known as ammonia water, ammonium hydroxide, ammoniacal liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or (inaccurately) ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH 3 (aq). Although the name ammonium hydroxide suggests a salt with the composition [NH + 4][OH −

    Ammonia is also tolerant to mineral oils and low sensitivity to small amounts of water in the system. [15] The vaporization heat of ammonia is high and the flow rate low, which requires different technologies to be used than other refrigerants. The low flow rate has historically limited ammonia to larger capacity systems. [16]
