In the oil and gas industry, activated carbon is commonly used in amine units to remove H2S and CO2 from hydrocarbon vapors. During the desulphurization of MDEA (Medium-Density Acid Emulsion Extraction) or its complex solutions, foaming and scaling of the amine solution typically occur, significantly reducing the purification effect.

1. Core Functions

 Contaminant Adsorption:  Activated carbon efficiently adsorbs impurities in amine solutions, preventing equipment corrosion and efficiency loss.

 Fogging Control:  Significantly reduces the risk of foaming in amine solutions by removing contaminants.

2. Industry Applications

 Oil Refining and Natural Gas Processing:  Commonly used in desulfurization units to purify MDEA solutions.

 Polysilicon Production:  Also used in processes such as hydrogen purification.

3. Technological Advantages

 High-Efficiency Purification: Significantly improves the cleanliness and stability of amine solutions.

 Equipment Protection:  Reduces scaling and corrosion, extending equipment lifespan.
