  2. Lime sulfur - Wikipedia

    en.wikipedia.org/wiki/Lime_sulfur

    Lime sulfur reacts with strong acids (including stomach acid) to produce highly toxic hydrogen sulfide (rotten egg gas) and indeed usually has a distinct "rotten egg" odor to it. Lime sulfur is not flammable but can release highly irritating sulfur dioxide gas when in a fire. Safety goggles and impervious gloves must be worn while handling lime ...

    en.wikipedia.org/wiki/Biodesulfurization

    Crude oil contains sulfur in its composition, with the latter being the most abundant element after carbon and hydrogen. [2] Depending on its source, the amount of sulfur present in crude oil can range from 0.05 to 10%. [3] Accordingly, the oil can be classified as sweet or sour if the sulfur concentration is below or above 0.5%, respectively. [4]

    en.wikipedia.org/wiki/Desulfurization

    Desulfurization or desulphurisation is a chemical process for the removal of sulfur from a material. [1] The term usually refers to the removal of sulfur from a molecule or a material by hydrogenolysis: [2] R 2 S + 2 H 2 → 2RH + H 2 S. Hydrogen is the ultimate sulfur acceptor. As applied to oil refinery streams, the conversion is known as ...

    Milk of sulfur (lac sulphuris) – formed by adding an acid to thion hudor (lime sulfur). Natron/soda ash/soda – sodium carbonate. Na 2 CO 3; Nitrum flammans – ammonium nitrate. Sugar of lead – lead(II) acetate, formed by dissolving lead oxide in vinegar. Thion hudor – lime sulfur, formed by boiling flowers of sulfur with slaked lime.

  6. Flue-gas desulfurization - Wikipedia

    en.wikipedia.org/wiki/Flue-gas_desulfurization

    An alternative to removing sulfur from the flue gases after burning is to remove the sulfur from the fuel before or during combustion. Hydrodesulfurization of fuel has been used for treating fuel oils before use. Fluidized bed combustion adds lime to the fuel during combustion. The lime reacts with the SO 2 to form sulfates which become part of ...
