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.
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 ...

[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 ...
Narrow-bore columns (1–2 mm) are used for applications when more sensitivity is desired either with special UV-vis detectors, fluorescence detection or with other detection methods like liquid chromatography-mass spectrometry. Capillary columns (under 0.3 mm) are used almost exclusively with alternative detection means such as mass spectrometry.
Several researchers proposed the installation of degassing columns from rafts in the middle of the lake. [ 22 ] [ 23 ] The principle is to slowly vent the CO 2 by lifting heavily saturated water from the bottom of the lake through a pipe, initially by using a pump, but only until the release of gas inside the pipe naturally lifts the column of ...
Structured packing. The term structured packing refers to a range of specially designed materials for use in absorption and distillation columns. [1] Structured packings typically consist of thin corrugated metal plates or gauzes arranged in a way that force fluids to take complicated paths through the column, thereby creating a large surface area for contact between different phases.
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 ...
