In 2018, high oil prices resulted in an extended summer shutdown of European ammonia factories causing a commercial CO 2 shortage, thus limiting production of CO 2-based products such as beer and soft drinks. [30] This situation repeated in September 2021 due to a 250-400% increase in the wholesale price of natural gas over the course of the year.
Anhydrous ammonia is classified as toxic (T) and dangerous for the environment (N). The gas is flammable ( autoignition temperature : 651 °C) and can form explosive mixtures with air (16–25%). The permissible exposure limit (PEL) in the United States is 50 ppm (35 mg/m 3 ), while the IDLH concentration is estimated at 300 ppm.
This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium.
The refinery was built in 1906 by the National Refining Company, which was then the second largest oil company in the United States.Built on 75 acres (30 ha), the refinery processed 2,500 barrels per day (400 m 3 /d) of crude oil, compared to today's 108,000-barrel-per-day (17,200 m 3 /d) processing capacity.
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).

The United States produces 9–10 million tons of hydrogen per year, mostly with steam reforming of natural gas. [13] The worldwide ammonia production, using hydrogen derived from steam reforming, was 144 million tonnes in 2018. [14] The energy consumption has been reduced from 100 GJ/tonne of ammonia in 1920 to 27 GJ by 2019. [15]
At 15.6 °C (60.1 °F), the density of a saturated solution is 0.88 g/ml; it contains 35.6% ammonia by mass, 308 grams of ammonia per litre of solution, and has a molarity of approximately 18 mol/L. At higher temperatures, the molarity of the saturated solution decreases and the density increases. [ 8 ]
