This unit procedure simulates the performance of a packed bed adsorption column that handles gaseous streams. Granular activated carbon is the default adsorbent and the objective is to remove hydrophobic organic compounds from a gaseous stream (typically air). These are first adsorbed on the packing during the adsorption phase and are then desorbed to a regeneration gas (typically steam, hot air, or hot inert gas) fed to the column during the regeneration phase.
● Feed: the designated input port for the gaseous feed.
● Regenerant In: the designated input port for the regeneration gas.
● Regenerant Out: the designated output port for the regeneration gas.
● Product: the designated output port for the gaseous feed.
The following operation types are currently supported in the context of this unit procedure:
● Adsorb, see Packed-Bed Adsorption
● Hold, see Holding
Note that procedure Hold is only available in semi-continuous operating mode.
The following procedures offer a similar functionality:
● Granular Activated Carbon (GAC) Adsorption Procedure (for Liquid Streams)
● Packed Bed Adsorption (PBA) Chromatography Procedure (Simplified)
