Enquire NowMethyldiethanolamine is used as an intermediate in the synthesis of numerous products. Its unique chemistry has resulted in its use in diverse areas, including coatings, textile lubricants, polishes, detergents, pesticides, personal-care products, pharmaceuticals, urethane catalysts, and water-treatment chemicals. Methyldiethanolamine is also used in gas treatment.
<p style="text-align: justify;">
<span style="text-align: justify;">Methyl Diethanolamine MDEA-based solvent designed for the selective removal of H2S from H2S and CO2 containing gas streams. The removal of sour or acid gas components such as hydrogen sulfide (H2S) or carbon dioxide (CO2) from gas streams is a common process, known as acid gas removal or gas sweetening. These impurities have to be eliminated or reduced to a specified level, for a variety of reasons: toxicity (H2S), corrosiveness of the gas, low caloric value, environment or other reasons depending on the application of the gas.</span></p>

</div>
<div>
<div style="text-align: justify;">
Methyl Diethanolamine is miscible in all proportions with water. It is also soluble in most organic solvents. Chemically it acts as both a tertiary amine and an alcohol. Neutralisation of the amino function by acids results in salt formation. The product is stable at elevated temperatures but must be kept away from oxidants and acids.</div>

<strong>Amine Gas Treatment Unit system simulation:</strong><br />
</div>
<div style="text-align: justify;">
Based upon feed gas conditions, the installation design and type of amine, unit performance can be predicted and optimized. The simulation output and reporting are tailored towards your needs and focus on the issues at hand. These simulations combined with our application experience allow us to provide you with feedback on how to improve the amine gas treatment unit operations (financial, operational and quality) and to tailor our amine formulations to maximize performance, such as energy reduction and reduced amine consumption.</div>
