Use / Application

1. DGA is essentially colorless, slightly viscous liquid with a mild amine odor.

DGA is miscible with water, alcohols, and aromatic hydrocarbons, but

relatively immiscible with aliphatic hydrocarbons and ethyl ether. Isometric with

diethanolamine; however, the primary H2N group makes it more reactive.

C4H11NO2

APPLICATIONS • Used for carbonyl sulfide (COS) removal from liquid

hydrocarbon streams

• Used as a selective solvent for recovery of aromatics from

refinery streams

• Removes carbon dioxide (CO2) and hydrogen sulfide (H2S)

from natural and refinery gas, aliphatic hydrocarbon liquids and other sour

hydrocarbon steams.

•Preparation of foam stabilizers, wetting and emulsifying agents,

condensation polymers, photoresist strippers, and amides for personal care

and metalworking applications.

2. 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.[1][2][3] It is a commonunit process used

in refineries, and is also used in petrochemical plants, natural

gas processing plants and other industries.

Processes within oil refineries or chemical processing plants

that remove hydrogen sulfide are referred to as "sweetening"

processes because the odor of the processed products is

improved by the absence of hydrogen sulfide. An alternative

to the use of amines involves membrane technology. However,

membrane separation is less attractive due to the relatively

high capital and operating costs as well as other technical

factors.[4]

Many different amines are used in gas treating:

Diethanolamine (DEA)

Monoethanolamine (MEA)

Methyldiethanolamine (MDEA)

Diisopropanolamine (DIPA)

Aminoethoxyethanol (Diglycolamine) (DGA)

The most commonly used amines in industrial plants are the

alkanolamines DEA, MEA, and MDEA. These amines are also

used in many oil refineries to removesour gases from liquid

hydrocarbons such as liquified petroleum gas (LPG).
