High Quality Ethanolamine/ Monoethanolamine (MEA) CAS 141-43-5

Short Description:

Monoethanolamine is a solvent used in the coal-fired power stations for absorbing post-combustion CO2 emissions. The solvent is readily available, its cost is low, and its absorption rate is fast. However, the parasitic energy consumption and the capital cost involved in an MEA-based post-combustion capture system is a hindrance to its use.

Product Description

MEA can be produced by reacting ammonia/water with ethylene oxide at a pressure of 50–70 bar to keep ammonia in the liquid phase. The process is exothermic and does not require any catalyst. The ratio of ammonia and ethylene oxide plays a significant role in deciding the composition of the resulting mixture. If ammonia reacts with one mole of ethylene oxide, monoethanolamine is formed, with two molecules of ethylene oxide, diethanolamine is formed whereas with three moles of ethylene oxide triethanolamine is formed. After the reaction, the distillation of the resulting mixture is carried out first to remove excess ammonia and water. Then the amines are separated using a three-step distillation setup.

Application

Chemical reagents, solvents, emulsifiers
Rubber accelerators, corrosion inhibitors, deactivators

Monoethanolamine is used as chemical reagents, pesticides, medicines, solvents, dye intermediates, rubber accelerators, corrosion inhibitors and surfactants, etc. It is also used as acid gas absorbents, emulsifiers, plasticizers, rubber vulcanizing agents, printing and dyeing Whitening agent, fabric anti-moth agent, etc. It can also be used as a plasticizer, vulcanizing agent, accelerator and foaming agent for synthetic resins and rubber, as well as intermediates for pesticides, medicines and dyes. It is also a raw material for synthetic detergents, emulsifiers for cosmetics, etc. Textile industry as printing and dyeing brightener, antistatic agent, anti-moth agent, detergent. It can also be used as a carbon dioxide absorber, ink additive, and petroleum additive.

Advantage

Product quality, sufficient quantity, effective delivery, high quality of service It has an advantage over a similar amine, ethanolamine, in that a higher concentration may be used for the same corrosion potential. This allows refiners to scrub hydrogen sulfide at a lower circulating amine rate with less overall energy usage.
