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 ...
The term became a common word. The original method of degaussing was to install electromagnetic coils into the ships, known as coiling. In addition to being able to bias the ship continually, coiling also allowed the bias field to be reversed in the southern hemisphere, where the mines were set to detect "N-pole down" fields.
[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 ...
Bubble columns offer a significant number of advantages: excellent heat and mass transfer between the phases, low operating and maintenance costs due to the absence of moving parts, solids can be handled without any erosion or plugging problems, slow reactions can be carried out due to the high liquid residence time (this is the case for gas ...
"Vacuum degassing is the process of removing gases from compounds using vacuum which become entrapped in the mixture when mixing the components." [2] To assure a bubble-free mold when mixing resin and silicone rubbers and slower-setting harder resins, a vacuum chamber is required. A small vacuum chamber is needed for de-airing (eliminating air ...
It is believed that about 1.2 cubic kilometres (4.2 × 10 10 cu ft) of gas was released. [13] The normally blue waters of the lake turned a deep red after the outgassing, due to iron-rich water from the deep rising to the surface and being oxidised by the air. The level of the lake dropped by about a metre [14] and trees near the lake were ...
Since its introduction in 1989, this gas recirculation method has been increasingly used by major aluminum producers. [3] An example of analyzer for direct hydrogen measurement in liquid aluminium is the Accurity. It works with a probe immersed in liquid aluminium and it uses the closed-loop recirculation method.
