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.
Engineers in a cleanroom, using CO 2 snow to clean a gold-coated test mirror for the James Webb Space Telescope. Carbon dioxide cleaning (CO 2 cleaning) comprises a family of methods for parts cleaning and sterilization, using carbon dioxide in its various phases. [1]
Dry-ice blasting can be used to clean food processing equipment. [11] As early as 2004, the UK Food Standards Agency documented the process to effectively decontaminate surfaces of Salmonella enteritidis , E. coli , and Listeria monocytogenes such that these microorganisms are not detectable using conventional microbiological methods.

Hot potassium carbonate, HPC, is a method used to remove carbon dioxide from gas mixtures, [1] in some contexts referred to as carbon scrubbing.The inorganic, basic compound potassium carbonate is mixed with a gas mixture and the liquid absorbs carbon dioxide through chemical processes. [2]
Amine gas plant at a natural gas field. Amine gas treating, also known as amine scrubbing, gas sweetening and acid gas removal, refers to a group of processes that use aqueous solutions of various alkylamines (commonly referred to simply as amines) to remove hydrogen sulfide (H 2 S) and carbon dioxide (CO 2) from gases.
The exhaust gases of combustion may contain substances considered harmful to the environment, and the scrubber may remove or neutralize those. A wet scrubber is used for cleaning air, fuel gas or other gases of various pollutants and dust particles. Wet scrubbing works via the contact of target compounds or particulate matter with the scrubbing ...
Carbon dioxide scrubbing may refer to: Carbon dioxide scrubber , a device that absorbs carbon dioxide Carbon capture and storage , the capture of carbon dioxide from large point sources
