  2. UAN - Wikipedia

    en.wikipedia.org/wiki/UAN

    Other grades are UAN 28, UAN 30 and UAN 18. The solutions are quite corrosive towards mild steel (up to 0.5 inches (1.3 cm) per year on C1010 steel) and are therefore generally equipped with a corrosion inhibitor to protect tanks, pipelines, nozzles, etc. Urea–ammonium nitrate solutions should not be combined with calcium ammonium nitrate ...

    en.wikipedia.org/wiki/Fertilizer

    Calcium ammonium nitrate Is a blend of 20-30% limestone CaCO 3 or dolomite (Ca,Mg)CO 3 and 70-80% ammonium nitrate with 24-28 % nitrogen. Calcium nitrate with 15,5% nitrogen and 19% calcium, reportedly holding a small share of the nitrogen fertilizer market (4% in 2007). [28] The main straight phosphate fertilizers are the superphosphates:

    A type Ia supernova explosion gives off 1– 2 × 10 44 joules of energy, which is about 2.4–4.8 hundred billion yottatons (24–48 octillion (2.4– 4.8 × 10 28) megatons) of TNT, equivalent to the explosive force of a quantity of TNT over a trillion (10 12) times the mass of the planet Earth.

    (pl.) aboiteaux A sluice or conduit built beneath a coastal dike, with a hinged gate or a one-way valve that closes during high tide, preventing salt water from flowing into the sluice and flooding the land behind the dike, but remains open during low tide, allowing fresh water precipitation and irrigation runoff to drain from the land into the sea; or a method of land reclamation which relies ...

    In the light road vehicle segment including passenger cars, by the end of 2022, 70,200 fuel cell electric vehicles had been sold worldwide, [29] compared with 26 million plug-in electric vehicles. [30] With the rapid rise of electric vehicles and associated battery technology and infrastructure, hydrogen's role in cars is minuscule. [27] [28]

  7. Greenhouse gas emissions - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas_emissions

    The sharp acceleration in CO 2 emissions since 2000 to more than a 3% increase per year (more than 2 ppm per year) from 1.1% per year during the 1990s is attributable to the lapse of formerly declining trends in carbon intensity of both developing and developed nations. China was responsible for most of global growth in emissions during this ...

  8. Ammonia - Wikipedia

    en.wikipedia.org/wiki/Ammonia

    The hazards of ammonia solutions depend on the concentration: 'dilute' ammonia solutions are usually 5–10% by weight (< 5.62 mol/L); 'concentrated' solutions are usually prepared at >25% by weight. A 25% (by weight) solution has a density of 0.907 g/cm 3 , and a solution that has a lower density will be more concentrated.

    Fulcrum predicted that the plant would produce approximately 10.5 million gallons per year of Fischer-Tropsch products from nearly 200,000 tons per year of MSW. [21] The total exported product amounted to just 350 gallons of syncrude which were transported to Marathon Petroleum 's refinery for conversion into jet fuel .
