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 …
Highly efficient capture and removal of H2S by multi-amine ...
2023年12月15日 · Xiong et al. developed a series of mild, green, and effective methods for capture and catalytic conversion of H 2 S into mercaptan alcohols, mercaptan acids, thiols or, thioethers by using special ILs. This method is also a promising strategy in H 2 S removal since it avoids the desorption phase [30], [31], [32].
Hydrogen sulfide capture and removal technologies: A …
2022年10月1日 · Hydrogen sulfide is a highly flammable, acutely toxic, and extremely hazardous gas that must be captured and removed from a number of important gaseous and liquid streams. This long-standing challenge of capturing H 2 S has seen the rise of different materials used in different types of technologies over the years.
Role of Amine Structure on Hydrogen Sulfide Capture from …
2018年5月1日 · H 2 S adsorption isotherms and cyclic studies are presented for these materials, and it is shown that secondary amines have the best amine efficiency while tertiary amines are the most stable for H 2 S capture, of the materials studied.
Evaluation of amine-based ionic liquids as potential solvents for ...
2024年3月1日 · This study presents a novel approach of hydrogen sulfide absorption by utilizing a series of unexplored amine-based ILs. The objective of this study is to screen potential ILs for effective H 2 S absorption by COSMO-RS.
The acid gases (CO2and/or H2S) react and are absorbed by the solvent according to reactions 1 to 6 below. The reaction with H2S, which is the same irrespective of the type of amine considered, consists of direct proton transfer (Reaction 1), where R1, R2and R3represent alkyl groups or a hydrogen atom.
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.
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).
Selective Removal of H2S from Biogas Using Solid Amine-Based …
In this work, a tertiary-amine-based “molecular basket” sorbent with a mesoporous silica as support was found to be effective for the selective hydrogen sulfide (H 2 S) removal from gas mixtures simulating biogas with a high CO 2 concentration up to 40 vol %.
H2S Scavenging: Amine Systems - GATE Energy
2014年6月30日 · This GATEKEEPER focuses on Amine Systems, one of the most commonly used regenerative H2S scavengers in the Oil & Gas industry. Amine Amines are organic compounds derived from ammonia with substitution of one or all of the hydrogens with alkyl or aryl groups, retaining a basic nitrogen atom with one lone pair of electrons.
