Absorption In Wetted Wall Column Apparatus

Product Details:

The set up consists of a glass column. Alkaline liquid is fed at the top of the column along the walls to create a laminar liquid flow along the walls of a wetted wall column. Flow rates of Air and CO2 are measured separately, mixed in a mixing chamber and then passed through the column vertically upward and absorbed in liquid film around the wall. All the flow rates can be independently varied to simulate different conditions. Liquid Sample can be taken out from the sampling point at the bottom of the column for analysis
