What is an amine plant?
WHAT ARE AMINE PLANTS? Amine treating plants remove CO2 (carbon dioxide) and H2S (hydrogen sulfide) from natural gas. The process is known as gas sweetening or acid gas removal, using various alkanolamines, commonly referred to as amines.
How is MDEA made?
Production. MDEA is produced by ethoxylation of methylamine using ethylene oxide: CH3NH2 + 2 C2H4O → CH3N(C2H4OH) Another route involves hydroxymethylation of diethanolamine followed by hydrogenolysis.
What is aqueous amine?
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 (H2S) and carbon dioxide (CO2) from gases.
Is MDEA hazardous?

Where is amine used?
Amines are used in making azo-dyes and nylon apart from medicines and drugs. They are widely used in developing chemicals for crop protection, medication and water purification. They also find use in products of personal care.
What is MDEA?
Methyldiethanolamine (MDEA) is a tertiary amine and commonly used for removal of acid gases from gas streams.
Is MDEA soluble in water?
A colorless to yellow liquid tertiary amine compound with an ammonia-like odor. It is completely soluble in water.
Is amine toxic?
Most aliphatic amines are not highly toxic, and many are harmless, natural components of foods and pharmaceuticals.
What are amines good for?
Amines are used in making azo-dyes and nylon apart from medicines and drugs. They are widely used in developing chemicals for crop protection, medication and water purification. They also find use in products of personal care. Ethanol amines are the most common type of amine used in the global market.
What are amines used for?
What is the pH of MDEA?
The pH = 5–7 was found to be the most effective level of pH in degradation of MDEA.
Is MDEA a tertiary amine?
MDEA is a tertiary amine, which, like the other amines, is used to sweeten natural gas streams. Major advantage over other amine processes is MDEA can be used to selectivity remove H 2 S in the presence of CO 2.
What is the name of the compound MDEA?
Methyl diethanolamine. Methyl diethanolamine, also known as N -methyl diethanolamine and more commonly as MDEA, is the organic compound with the formula CH 3 N(C 2 H 4 OH) 2. It is a, colorless liquid with an ammonia odor. It is miscible with water, alcohol and benzene. A tertiary amine, it is widely used as a sweetening agent in…
What is MDEA (methyl diethanolamine)?
Methyl diethanolamine, also known as N-methyl diethanolamine and more commonly as MDEA, is the organic compound with the formula CH 3N(C 2H 4OH) 2.
Why is MDEA more heat resistant than primary amines?
MDEA solutions have the highest loading compared to any primary or secondary amine, which makes their circulation rate the lowest. MDEA has the lowest heat requirements for regeneration as it has the lowest heats of reaction with H 2 S and CO 2. Beside this it has the lowest specific heat solvent losses and a low the freezing point (about − 32°C).
