    en.wikipedia.org/wiki/Degassing

    Degassing, also known as degasification, is the removal of dissolved gases from liquids, especially water or aqueous solutions. There are numerous methods for removing gases from liquids. There are numerous methods for removing gases from liquids.

  3. Degas conductivity - Wikipedia

    en.wikipedia.org/wiki/Degas_conductivity

    There are generally two methods for removing carbon dioxide from the water sample: use of a reboiler to heat the sample and expel the CO 2, and use of inert gasses. In the latter method, an inert gas which does not contain CO 2 is passed through the sample water, whereby the gas components in the sample water are displaced by the gas components ...

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

    [2] [3] For example, before casting aluminium alloys, argon bubbles are injected into liquid aluminium using a rotary degasser. The argon bubbles rise to the surface, bringing with them some of the dissolved hydrogen. The degassing step reduces the occurrence of hydrogen gas porosity. In the steel making process, this method is used very ...

    The sample mixture to be separated and analyzed is introduced, in a discrete small volume (typically microliters), into the stream of mobile phase percolating through the column. The components of the sample move through the column, each at a different velocity, which are a function of specific physical interactions with the adsorbent, the ...

    Within Excel, the goal seek function can be used to set column 15 to 0 by changing the depth estimate in column 2 instead of iterating manually. Table 1: Spreadsheet of Newton Raphson Method of downstream water surface elevation calculations Step 5: Combine the results from the different profiles and display.

  8. Fenske equation - Wikipedia

    en.wikipedia.org/wiki/Fenske_equation

    Fractionation at total reflux. The Fenske equation in continuous fractional distillation is an equation used for calculating the minimum number of theoretical plates required for the separation of a binary feed stream by a fractionation column that is being operated at total reflux (i.e., which means that no overhead product distillate is being withdrawn from the column).

  9. Degasser - Wikipedia

    en.wikipedia.org/wiki/Degasser

    For a small amount of entrained gas in a drilling fluid, the degasser can play a major role of removing small bubbles that a liquid film has enveloped and entrapped. [1] In order for it to be released and break out the air and gas such as methane, H 2 S and CO 2 from the mud to the surface, the drilling fluid must pass through a degassing technique, and it can be accomplished by the equipment ...
