  2. Factorio - Wikipedia

    en.wikipedia.org/wiki/Factorio

    Factorio is a construction and management simulation game developed and published by Czech studio Wube Software. The game was announced via an Indiegogo crowdfunding campaign in 2013 and released for Windows , macOS , and Linux on 14 August 2020 following an early access phase, which was made available on 25 February 2016.

  3. Contact process - Wikipedia

    en.wikipedia.org/wiki/Contact_process

    The contact process is a method of producing sulfuric acid in the high concentrations needed for industrial processes. Platinum was originally used as the catalyst for this reaction; however, because it is susceptible to reacting with arsenic impurities in the sulfur feedstock, vanadium(V) oxide (V 2 O 5) has since been preferred.

  4. Claus process - Wikipedia

    en.wikipedia.org/wiki/Claus_process

    The vast majority of the 64,000,000 tonnes of sulfur produced worldwide in 2005 was byproduct sulfur from refineries and other hydrocarbon processing plants. [3] [4] [5] Sulfur is used for manufacturing sulfuric acid, medicine, cosmetics, fertilizers and rubber products. Elemental sulfur is used as fertilizer and pesticide.

  5. Frasch process - Wikipedia

    en.wikipedia.org/wiki/Frasch_process

    Sulfur (m.p. 115 °C) melts and flows into the middle tube. Water pressure alone is unable to force the sulfur into the surface due to the molten sulfur's greater density, so hot air is introduced via the innermost tube to froth the sulfur, making it less dense, and pushing it to the surface. [1] The sulfur obtained can be very pure (99.7 - 99.8%).

  6. Sulfation - Wikipedia

    en.wikipedia.org/wiki/Sulfation

    To minimize the problem, the combustion is often conducted in the presence of calcium oxide or calcium carbonate, which, directly or indirectly, bind sulfur dioxide and some oxygen to give calcium sulfite. [1] The net reaction is: CaO + SO 2 → CaSO 3 2 CaSO 3 + O 2 → 2 CaSO 4. or the net reaction is sulfation, the addition of SO 3: CaO + SO ...

  7. Smelting - Wikipedia

    en.wikipedia.org/wiki/Smelting

    Smelting involves more than just melting the metal out of its ore. Most ores are the chemical compound of the metal and other elements, such as oxygen (as an oxide), sulfur (as a sulfide), or carbon and oxygen together (as a carbonate). To extract the metal, workers must make these compounds undergo a chemical reaction.
