A carbon dioxide scrubber is a piece of equipment that absorbs carbon dioxide (CO 2). It is used to treat exhaust gases from industrial plants or from exhaled air in life support systems such as rebreathers or in spacecraft , submersible craft or airtight chambers .
Soda lime canister used in anaesthetic machines to act as a carbon dioxide scrubber. Soda lime, a mixture of sodium hydroxide (NaOH) and calcium oxide (CaO), is used in granular form within recirculating breathing environments like general anesthesia and its breathing circuit, submarines, rebreathers, and hyperbaric chambers and underwater habitats.
The scrubber is usually between the breathing hose and the counterlung bag, and gas flow is bi-directional. All of the flow passages between the user and the active absorbent in the scrubber are dead space – volume containing gas which is rebreathed without modification by the rebreather. The dead space increases as the absorbent is depleted.
Scrubber systems (e.g. chemical scrubbers, gas scrubbers) are a diverse group of air pollution control devices that can be used to remove some particulates and/or gases from industrial exhaust streams. An early application of a carbon dioxide scrubber was in the submarine the Ictíneo I, in 1859; a role for which they continue to be used today ...
MSCs were initially conceived of in an attempt to create an improved version of the simplistic folboat. [1] It was created by the Allied Inter-Services Research Bureau [2] and designed by Major Hugh Reeves, R.E., [3] who was also given the task of designing an 'unspecified device' for an underwater approach [citation needed] at the confidential research area Station IX. based on an idea from ...
In rebreather diving, the typical effective endurance of the scrubber will be half an hour to several hours of breathing, depending on the type and size of the scrubber, the absorbent characteristics, the ambient temperature and pressure, the operational mechanics of the rebreather, and the amount of carbon dioxide produced by the diver, which ...
Mir (Russian: Мир, lit. 'world, peace') was a class of two self-propelled deep-submergence vehicles.The project was initially developed by the USSR Academy of Sciences (now the Russian Academy of Sciences) along with Lazurit Central Design Bureau, and two vehicles were ordered from Finland.
The French Daphne-class diesel–electric submarine Minerve was lost with all hands in bad weather while returning to her home port of Toulon in January 1968. Minerve was one of four submarines lost to unknown causes in 1968 along with the Soviet submarine K-129, the American USS Scorpion, and Israeli submarine INS Dakar.
