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.
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. Carbon dioxide scrubbers are also used in controlled atmosphere (CA) storage and ...
Solid sorbents for carbon capture include a diverse range of porous, solid-phase materials, including mesoporous silicas, zeolites, and metal-organic frameworks.These have the potential to function as more efficient alternatives to amine gas treating processes for selectively removing CO 2 from large, stationary sources including power stations.

MEA carbon dioxide scrubbing is also used to regenerate the air on submarines. Solutions of MEA in water are used as a gas stream scrubbing liquid in amine treaters. [21] For example, aqueous MEA is used to remove carbon dioxide (CO 2) and hydrogen sulfide (H 2 S) from various gas streams; e.g., flue gas and sour natural gas. [22]
A typical amine gas treating process flow diagram. Ionic liquids for use in CO 2 capture by absorption could follow a similar process.. A typical CO 2 absorption process consists of a feed gas, an absorption column, a stripper column, and output streams of CO 2-rich gas to be sequestered, and CO 2-poor gas to be released to the atmosphere.
The Saskatchewan Government's Boundary Dam Integrated Carbon Capture and Sequestration Demonstration Project will use post-combustion, amine-based scrubber technology to capture 90% of the CO 2 emitted by Unit 3 of the power plant; this CO 2 will be pipelined to and utilized for enhanced oil recovery in the Weyburn oil fields.

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 ...
Calcium looping (CaL), or the regenerative calcium cycle (RCC), is a second-generation carbon capture technology. [1] It is the most developed form of carbonate looping, where a metal (M) is reversibly reacted between its carbonate form (MCO 3) and its oxide form (MO) to separate carbon dioxide from other gases coming from either power generation or an industrial plant.
