Gas Absorption Unit (GAC100)
The gas absorption unit is used to absorb a component from a gas stream into a liquid phase. In the process, continuous contact of gas and liquid in counter-current flow on packing surfaces facilitates mass transfer from gas phase to liquid phase. In this unit, gas concentration profile and pressure profile across the column is measured. Gas and liquid flow rates are measured using rotameters. Gas concentration is measured "in place" using a gas analyzer system integrated into the unit.
