Amine gas treating - Wikipedia
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.
Chemical and physical systems for sour gas removal: An overview …
2022年10月1日 · The chemisorption mechanism of sour gas by aqueous amines based-solvents has been experimentally and computationally investigated by several research groups (Hwang et al., 2014; Kortunov et al., 2015). For CO 2 capture, two main mechanisms have been highlighted, the thermomolecular mechanism and the zwitterion mechanism. In both processes, the ...
Sour gas - Wikipedia
Sour gas is natural gas or any other gas containing significant amounts of hydrogen sulfide (H 2 S). Natural gas is usually considered sour if there are more than 5.7 milligrams of H 2 S per cubic meter of natural gas, which is equivalent to approximately 4 ppm by volume under standard temperature and pressure. [1][2] However, this threshold ...
Introduction to amine sweetening processes - ScienceDirect
2022年1月1日 · Amine gas (or LPG) treating units, sometimes referred as sweetening of sour gases/sour LPG (reference to the gas odor improvement), amine gas scrubbing, and acid gas removal, are processes to remove hydrogen sulfide (H 2 S) and carbon dioxide (CO 2) from gas streams using various types of alkylamines. These processes are commonly used in ...
Refinery Gas Treating Processes - SpringerLink
2015年1月1日 · Removal of the acid gases in the refinery streams is required either to purify a gas stream for further use in a process or for environmental reasons. This chapter describes the most common sour gas treating processes. Design techniques are provided for the amine-based approaches along with a design example.
Amine treatment in the oil & gas industry - KROHNE Group
Amine gas treatment is a process that uses aqueous solutions of various alkylamines (known as amines) to dissolve and remove hydrogen sulfide and carbon dioxide from the refinery sour gases, producing ‘sweet gas’. This leads to the process being known as ‘gas sweetening’, but it is also known as amine scrubbing, or acid gas removal.
Acid Gas Removal Unit (AGRU) | Amine Gas Treating - Pall
Amine scrubbing/acid gas removal processes utilize amines or specialty solvents to remove acid gases such as H2S and/or CO2 from Refinery Fuel Gas (RFG) to meet the gas quality specifications. The sour gas is contacted with lean amine in the contactor tower.
Amine Gas Treating: H2S and CO2 Removal | Vaisala
Amine gas treating, also known as gas sweetening, acid gas removal or amine scrubbing refers to a group of processes that use amines to remove H2S and CO2 from gases. Most acid gas recovery systems use either monoethanolamine (MEA), diethanol-amine (DEA) or methyldiethanolamine (MDEA).
Amine and acid gas treating - Shell Global
Treating amine in sour gas profitably. The end result is a sharper design that can result in CO₂ removal capacity increased up to 25% as well as up to 30% reduction in regeneration energy.
Sour gas reservoirs and sulfur-removal technologies: A collection …
2015年9月1日 · Collectively, these articles provide key insight to the progress being made towards better understanding of removal of sour gases and other components in gas streams using different techniques, sour gas reservoirs, and corrosion and safety issues in sour gas sweetening plants.
