When foaming in amine plant is caused by surface-active contaminants or dissolved or emulsified high molecular weight organic compounds, these agents may be eliminated by passage of the solution through a bed of activated carbon.
While it is generally agreed that activated carbon filtration should be considered for all amine units, it is highly recommended for secondary and tertiary amines (DEA, MDEA, and DIPA), which cannot be thermally reclaimed online like DGA and MEA.
A variety of activated carbons (8 × 30 mesh, 5 × 7 mesh, 4 × 10 mesh, etc.) derived from coal or wood have been used for amine filtration.
GP GasPack S.A. offers a wide range of Activated Carbon to provide high performance for your amine filtration application. For more information about an specific product, contact our technical team.
