The set up consists of a glass column packed with Rasching rings. Liquid is fed at the top of the column through distributor. The solute gas and air are measured separately, mixed in a mixing chamber and then passed through the packed column vertically upward and absorbed in liquid. 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
•An ENGLISH instruction manual consisting of experimental procedures, block diagram etc. will be provided along with the Apparatus.
•The whole set-up is well designed and arranged on a rigid structure painted with industrial PU Paint
