General Description

Monoethanolamine (MEA) is an organic compound derived from ammonia, widely used in the chemical and petrochemical industries.

This effective amine compound absorbs carbon dioxide (Co) and 2 other acids, making it indispensable in gas treatment and preparation processes.

Main Applications

PETROCHEMICAL INDUSTRY

• Gas purification and CO2 removal: Monoethanolamine is used in gas treatment systems at petrochemical plants for removing carbon dioxide from natural gas, oil, and gas products.

• Ammonia absorption: Applied in gas cleaning and distillation processes where ammonia removal is critical to prevent equipment corrosion and improve product quality.

• Hydrogen sulfide (H2S) removal: Used in natural gas cleaning technologies and hydrocarbon processing, where hydrogen sulfide absorption is necessary.

ENERGY AND GAS PROCESSING

• Applied in carbon dioxide absorption units and gas treatment systems in gas processing and energy plants.

• In amine gas sweetening systems, MEA is effectively used to remove harmful contaminants from gases entering energy and processing plants.

CHEMICAL INDUSTRY

• Soap and surfactant production: Used in the manufacture of cleaning agents and surfactants in
household and industrial chemistry.

• Rubber and plastics production: Used in processing and synthesizing polymers.

PHARMACEUTICALS AND COSMETICS

• Used as a neutralizing agent and in the production of active ingredients in the pharmaceutical industry.

• Included in cosmetics such as creams and lotions for pH regulation.

Advantages of Monoethanolamine (MEA)

• High efficiency in carbon dioxide and acid absorption processes.

• Low toxicity and safe use under proper storage and handling conditions.

• Versatility in various sectors, from gas processing to chemical and pharmaceutical industries.
