  2. SNOX process - Wikipedia

    en.wikipedia.org/wiki/SNOX_process

    The process is based on the well-known wet sulfuric acid process (WSA), a process for recovering sulfur from various process gasses in the form of commercial quality sulfuric acid (H 2 SO 4). [1] [2] [3] The SNOX process is based on catalytic reactions and does not consume water or absorbents.

  3. Hydrodesulfurization - Wikipedia

    en.wikipedia.org/wiki/Hydrodesulfurization

    Hydrodesulfurization or hydrodesulphurisation (Commonwealth English; see spelling differences) (HDS), also called hydrotreatment or hydrotreating, is a catalytic chemical process widely used to remove sulfur (S) from natural gas and from refined petroleum products, such as gasoline or petrol, jet fuel, kerosene, diesel fuel, and fuel oils.

  4. Sulfur water - Wikipedia

    en.wikipedia.org/wiki/Sulfur_water

    However, with a herd drinking high concentrate of sulfur water, ruminants may contract sulfur induced polioencephalomalacia (sPEM), which is a neurological disorder. Because of this finding, the study tries to reach the goal of finding a dietary supplement which can be used to counteract the negative health effects on the steers.

  5. Degassing - Wikipedia

    en.wikipedia.org/wiki/Degassing

    Chemists remove gases from solvents when the compounds they are working on are possibly air- or oxygen-sensitive (air-free technique), or when bubble formation at solid-liquid interfaces becomes a problem. The formation of gas bubbles when a liquid is frozen can also be undesirable, necessitating degassing beforehand.

  6. Wet sulfuric acid process - Wikipedia

    en.wikipedia.org/wiki/Wet_sulfuric_acid_process

    The WSA process can be applied in all industries where sulfur removal presents an issue. The wet catalysis process is used for processing sulfur-containing streams, such as: [1] H 2 S gas from e.g. amine gas treating unit; Off-gas from sour water stripper (SWS) gas; Off-gas from Rectisol; Spent acid from an alkylation unit; Claus process tail gas

  7. Amine gas treating - Wikipedia

    en.wikipedia.org/wiki/Amine_gas_treating

    In fact, the vast majority of the 64,000,000 metric tons of sulfur produced worldwide in 2005 was byproduct sulfur from refineries and other hydrocarbon processing plants. [7] [8] Another sulfur-removing process is the WSA process which recovers sulfur in any form as concentrated sulfuric acid. In some plants, more than one amine absorber unit ...
