  2. Fertilizer - Wikipedia

    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:

  3. Cracking (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Cracking_(chemistry)

    The hydrocracking process depends on the nature of the feedstock and the relative rates of the two competing reactions, hydrogenation and cracking. Heavy aromatic feedstock is converted into lighter products under a wide range of very high pressures (1,000–2,000 psi) and fairly high temperatures (750–1,500 °F, 400–800 °C), in the ...

  4. Liquid nitrogen - Wikipedia

    en.wikipedia.org/wiki/Liquid_nitrogen

    Liquid nitrogen is a compact and readily transported source of dry nitrogen gas, as it does not require pressurization. Further, its ability to maintain temperatures far below the freezing point of water, specific heat of 1040 J ⋅kg −1 ⋅K −1 and heat of vaporization of 200 kJ⋅kg −1 makes it extremely useful in a wide range of ...

  5. Nitrox - Wikipedia

    en.wikipedia.org/wiki/Nitrox

    Nitrox refers to any gas mixture composed (excepting trace gases) of nitrogen and oxygen that contains less than 78% nitrogen. [1] [2] In the usual application, underwater diving, nitrox is normally distinguished from air and handled differently. [3]

  6. Baker percentage - Wikipedia

    en.wikipedia.org/wiki/Baker_percentage

    In a recipe, the baker's percentage for water is referred to as the "hydration"; it is indicative of the stickiness of the dough and the "crumb" of the bread. Lower hydration rates (e.g., 50–57%) are typical for bagels and pretzels, and medium hydration levels (58–65%) are typical for breads and rolls. [25]

  7. Waste-to-energy - Wikipedia

    en.wikipedia.org/wiki/Waste-to-energy

    Incineration, the combustion of organic material such as waste with energy recovery, is the most common WtE implementation. All new WtE plants in OECD countries incinerating waste (residual MSW, commercial, industrial or RDF) must meet strict emission standards, including those on nitrogen oxides (NO x), sulphur dioxide (SO 2), heavy metals and dioxins.

  8. Greenhouse gas emissions by the United States - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas_emissions...

    In the United States, power generation was the largest source of emissions for many years, but in 2017, the transportation sector overtook it as the leading emissions source. As of that year, the breakdown was transportation at 29%, followed by electricity generation at 28% and industry at 22%. [25]
