ABSTRACT

Absorption is a diffusional mass-transfer operation by which a soluble gaseous component is removed from a gas stream by dissolution in a solvent liquid.1 A summary of absorption containing a general description, advantages, and disadvantages for the removal of volatile organic compounds (VOCs) from gaseous emission streams is provided below.2-4

• VOC gaseous emissions flow into the bottom of a packed or tray column and is distributed throughout the absorption column.
