It operates at a low pressure to maximise the amount of gas (eg methane, carbon dioxide) that is removed from the water stream. [8] It can be located immediately downstream of the production separators prior to low pressure water treatment system such as dissolved gas flotation. In this case the degasser may also act as a surge drum to ensure a ...
The solubility of gas obeys Henry's law, that is, the amount of a dissolved gas in a liquid is proportional to its partial pressure. Therefore, placing a solution under reduced pressure makes the dissolved gas less soluble. Sonication and stirring under reduced pressure can usually
In thermodynamics, the reduced properties of a fluid are a set of state variables scaled by the fluid's state properties at its critical point. These dimensionless thermodynamic coordinates, taken together with a substance's compressibility factor , provide the basis for the simplest form of the theorem of corresponding states .
A reduced pressure zone device (RPZD, RPZ, or RPZ valve) is a type of backflow prevention device used to protect water supplies from contamination. RPZDs may also be known as reduced pressure principle (RP), reduced pressure principle backflow prevention devices , [ 1 ] [ 2 ] reduced pressure zone assemblies (RPZA), [ 3 ] or reduced pressure ...
Vacuum distillation or distillation under reduced pressure is a type of distillation performed under reduced pressure, which allows the purification of compounds not readily distilled at ambient pressures or simply to save time or energy. This technique separates compounds based on differences in their boiling points.

A 2009 collaboration with Royal Dutch Shell saw the installation of a wireline at a record 2,673 feet (815 m) of water for repairing a safety valve. [ 24 ] On April 22, 2010, three Oceaneering ROV crews aboard the Oceaneering vessel Ocean Intervention III , the DOF ASA Skandi Neptune and the Boa International Boa Sub C began to map the seabed ...
