Carbon beds are an integral part of most amine based (MEA, DEA, MDEA, DIPA, DGA) gas treating units. In some cases, the carbon bed is on the rich amine stream, although it is often on the lean stream. In most cases, there is a small slip stream 5-25% (of the main flow) that contacts the carbon. The ostensible reason to use a carbon bed is for hydrocarbon removal.
