DEGRADATION OF MDEA (N-METHYL DIETHANOLAMINE):
Main oxidative degradation products of MDEA (N-methyl diethanolamine) include monoethanol amine (MEA), methyl-aminoethanol (MAE), diethanolamine (DEA), amino acids bicine, glycine and hydroxyethyl sarcosine (HES), formyl amides of MAE and DEA, ammonia, and stable salts formate, glycolate, acetate, and oxalate.

In an industrial plan that utilizes MDEA (N-methyl diethanolamine), oxidative degradation is most likely to shift to the cross exchanger where temperatures are greater than 70 °C.

Higher temperatures and higher CO2 loading accelerate the rate of degradation, resulting in an increase of alkalinity loss as well as total formate production.

While MDEA (N-methyl diethanolamine) is more resistant to degradation as a standalone compared to MEA, MDEA is preferentially degraded when in an MDEA/MEA blend.

Because of the formation of DEA and MAE, which could form nitroso-compounds or diethylnitrosamine and diethylnitraine, the blend could potentially have an adverse impact in terms of atmospheric admissions.

In the Boundary Dam plant, emissions increased when CO2 loading of lean amine increased for the blend and MEA.
However, decreasing the lean loading increases the reboiler heat duty, which results in an obvious tradeoff between emissions and heat duty or energy costs.

This compound should not be confused with the recreational drug methylenedioxyethylamphetamine which is also abbreviated MDEA (N-methyl diethanolamine).

Another route involves hydroxymethylation of diethanolamine followed by hydrogenolysis.

MDEA (N-METHYL DIETHANOLAMINE) BLENDS:
MDEA (N-methyl diethanolamine) is less reactive towards CO2, but has an equilibrium loading capacity approaching 1 mole CO2 per mole amine.
MDEA (N-methyl diethanolamine) also requires less energy to regenerate.

To combine the advantages of MDEA (N-methyl diethanolamine) and the smaller amines, MDEA is usually mixed with a catalytic promoter such as piperazine, PZ, or a fast reacting amine such as MEA to retain reactivity, but lower regeneration costs.
Activated MDEA (N-methyl diethanolamine) or aMDEA uses piperazine as a catalyst to increase the speed of the reaction with CO2.

MDEA (N-methyl diethanolamine) has been commercially successful.
Many tests have been done on the performance of MDEA (N-methyl diethanolamine)/MEA or MDEA (N-methyl diethanolamine)/piperazine mixtures compared to single amines.

CO2 production rates were higher than MEA for the same heat duty and total molar concentration when experiments were performed in the University of Regina pilot plant, which is a modeled after a natural gas plant.

There were also insignificant trace amounts of degradation products detected.
However, when the same control variables and tests were conducted at the Boundary Dam Power Station plant, the CO2 production rate for the mixed solvent was lower than MEA.

This was a result of the reduction in the capacity of the solvent to absorb CO2 after degradation.
Because the Boundary Dam plant is a coal-fired power plant, it operates under harsher environments and produces an impure flue gas containing, fly ash, SO2, and NO2 that are fed into carbon capture.

Even with flue gas pretreatment, there is still enough to produce degradation products such as straight chain amines and sulfur compounds, which accumulate so it is no longer possible to regenerate MEA and MDEA (N-methyl diethanolamine).
For these blends to be successful in reducing heat duty, their chemical stabilities must be maintained.

STORAGE OF MDEA (N-METHYL DIETHANOLAMINE):
MDEA (N-methyl diethanolamine) is stable under normal storage and use conditions, but elevated temperatures can cause it to decompose.
Decomposition products depend upon temperature, air supply, and the presence of other materials.
Avoid MDEA (N-methyl diethanolamine) contact with nitrites, strong acids, and strong oxidizers.

Avoid MDEA (N-methyl diethanolamine) unintended contact with halogenated hydrocarbons.
MDEA (N-methyl diethanolamine) can react with halogenated organics, resulting in temperature and/or pressure increases.

MDEA (N-methyl diethanolamine) is corrosive when wet.
Heating above 60°C (140°F) in the presence of aluminum can result in corrosion and generation of flammable hydrogen gas.
