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.
Carbon dioxide removal – Removal of atmospheric carbon dioxide through human activity; Greenhouse gas – Gas in an atmosphere with certain absorption characteristics; Rebreather – Portable apparatus to recycle breathing gas; Sabatier reaction – Methanation process of carbon dioxide with hydrogen
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.

Planting trees is a nature-based way to remove carbon dioxide from the atmosphere, however the effect may only be temporary in some cases. [1] [2]Carbon dioxide removal (CDR) is a process in which carbon dioxide (CO 2) is removed from the atmosphere by deliberate human activities and durably stored in geological, terrestrial, or ocean reservoirs, or in products.
Carbon dioxide removal is achieved when ambient air makes contact with chemical media, typically an aqueous alkaline solvent [4] or sorbents. [5] These chemical media are subsequently stripped of CO 2 through the application of energy (namely heat), resulting in a CO 2 stream that can undergo dehydration and compression, while simultaneously ...
The raw gas is then piped to a gas processing plant where the initial purification is usually the removal of acid gases (hydrogen sulfide and carbon dioxide). There are several processes available for that purpose as shown in the flow diagram, but amine treating is the process that was historically used. However, due to a range of performance ...
