2025 Conference Workshop:
Several processes are known for the removal of acidic gases such as H2S and CO2 from neutral industrial gases, most of which are based on absorption of the acidic gases by alkaline liquids. Such as Organic-alkanolamines (MEA, DEA etc.). During repeated recirculation of the absorbent, organic impurities accumulate in the absorbent. The organic impurities are usually degradation products having a corrosive nature. After prolonged use, the absorbent becomes corrosive to an extent, proportional to its age, and in addition becomes less effective for absorption of acid gases. Further, accumulation of higher hydrocarbons may give foaming problems in time.
In many systems, the gas treater liquid is purified with Granular Activated Carbon (GAC) or Extruded Activated Carbon (EAC) to remove the organic impurities to such an extent that the absorption system runs well.
The presentation will delve into how Norit's technical support can enhance gas scrubber system performance by assisting with the selection of optimal GAC or EAC types, providing technical input for filter design, supporting commissioning engineers during system setup, and offering detailed spent carbon sample analysis.
