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.
Beginning in 1970 the vessel served as an amine absorber tower, used to strip hydrogen sulfide from a process stream of propane and butane. In 1974, plant inspection identified hydrogen blisters and laminations in the shell of the vessel, and the refinery replaced several meters of the lower shell section using manual metal arc welding.
A carbon dioxide scrubber. 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.
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.

Simplified absorption column. Typical operating range: 35-50 °C and 5-205 atm of absolute pressure Amine blends that are activated by concentrated piperazine are used extensively in commercial CO 2 removal for carbon capture and storage (CCS) because piperazine advantageously allows for protection from significant thermal and oxidative ...

The project was completed in 2014. The retrofit utilized a post-combustion amine absorption technology. The captured CO 2 was to be sold to Cenovus to be used for Enhanced Oil Recovery (EOR) in Weyburn field. Any CO 2 not used for EOR was planned to be used by the Aquistore project and stored in deep saline aquifers. Many complications kept ...
