  3. Supercritical fluid extraction - Wikipedia

    en.wikipedia.org/wiki/Supercritical_fluid_extraction

    It then passes into the extraction vessel, where it rapidly diffuses into the solid matrix and dissolves the material to be extracted. The dissolved material is swept from the extraction cell into a separator at lower pressure, and the extracted material settles out. The CO 2 can then be cooled, re-compressed and recycled, or discharged to ...

  4. Merox - Wikipedia

    en.wikipedia.org/wiki/Merox

    Merox is an acronym for mercaptan oxidation.It is a proprietary catalytic chemical process developed by UOP used in oil refineries and natural gas processing plants to remove mercaptans from LPG, propane, butanes, light naphthas, kerosene, and jet fuel by converting them to liquid hydrocarbon disulfides.

    A schematic diagram of a demethanizer extracting hydrocarbon liquids from natural gas. Raw natural gas consists primarily of methane (CH 4), the shortest and lightest hydrocarbon molecule, along with various amounts of heavier hydrocarbon gases such as ethane (C 2 H 6), propane (C 3 H 8), normal butane (n-C 4 H 10), isobutane (i-C 4 H 10), pentanes and even higher-molecular-mass hydrocarbons.

    en.wikipedia.org/wiki/Separator_(oil_production)

    Oil and gas separators can have three general configurations: vertical, horizontal, and spherical.Vertical separators can vary in size from 10 or 12 inches in diameter and 4 to 5 feet seam to seam (S to S) up to 10 or 12 feet in diameter and 15 to 25 feet S to S. Horizontal separators may vary in size from 10 or 12 inches in diameter and 4 to 5 feet S to S up to 15 to 16 feet in diameter and ...

  7. Supercritical fluid - Wikipedia

    en.wikipedia.org/wiki/Supercritical_fluid

    The CO 2 is separated from other flue gases, compressed to the supercritical state, and injected into geological storage, possibly into existing oil fields to improve yields. At present, only schemes isolating fossil CO 2 from natural gas actually use carbon storage, (e.g., Sleipner gas field ), [ 35 ] but there are many plans for future CCS ...
