ADVANTAGES of METHYLDIETHANOLAMINE:
-Selectivity to hydrogen sulphide.
-Reduction of 30% in energy consumption.
-Increased productivity.
-Low corrosiveness.
-No resin formation.
-Reduction in circulating absorbent consumption.

METHYLDIETHANOLAMINE BLENDS:
Methyldiethanolamine is less reactive towards CO2, but has an equilibrium loading capacity approaching 1 mole CO2 per mole amine.
Methyldiethanolamine also requires less energy to regenerate.
To combine the advantages of Methyldiethanolamine and the smaller amines, Methyldiethanolamine 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 Methyldiethanolamine or aMDEA uses piperazine as a catalyst to increase the speed of the reaction with CO2.
It has been commercially successful.
Many tests have been done on the performance of Methyldiethanolamine/MEA or Methyldiethanolamine/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.
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 Methyldiethanolamine.
For these blends to be successful in reducing heat duty, their chemical stabilities must be maintained.

DEGRADATION of METHYLDIETHANOLAMINE:
Main oxidative degradation products of Methyldiethanolamine 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 Methyldiethanolamine, 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 Methyldiethanolamine is more resistant to degradation as a standalone compared to MEA, Methyldiethanolamine is preferentially degraded when in an Methyldiethanolamine/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.
Decreasing the lean loading increases the reboiler heat duty, which results in an obvious tradeoff between emissions and heat duty or energy costs.

PRODUCTION of METHYLDIETHANOLAMINE:
Methyldiethanolamine is produced by ethoxylation of methylamine using ethylene oxide:
CH3NH2 + 2 C2H4O → CH3N(C2H4OH)2

Methyldiethanolamine production consists of the following stages:
-Methyldiethanolamine synthesis.
-Methylamine distillation and recycling.
-Methylmonoethanolamine distillation and recycling.

-Separation of commercial methyldiethanolamine.
Synthesis is carried out in the liquid phase from ethylene oxide and methylamine in anhydrous medium, at a temperature of 60-90 °С and pressure up to 1 MPa.
The process is autocatalytic.
The technology is characterised by high quality commercial methyldiethanolamine and low energy consumption.
