Product Code : SCL-CLE-13442
Indian Lab Suppliers supplies the Absorption In Wetted Wall Column (Product ID: 13442) as part of its chemistry lab equipment range. It is a glass wetted-wall column in which CO2 from an air stream is absorbed into a thin alkaline liquid film running down the wall.
Quick Answer
Alkaline liquid is fed at the top so that it spreads over the inside wall of the 55 mm by about 750 mm borosilicate glass column as a laminar falling film. Air and CO2 are metered separately, mixed in a chamber and passed upward through the column, where CO2 is absorbed into the film. The liquid comes from a 20-litre stainless steel tank by compressed air (0–2 kg/cm² regulator and Bourdon gauge), each stream has its own rotameter, and spent liquid collects in a 10-litre stainless steel tank. Because the film area is known, this column gives a cleaner mass transfer coefficient than a packed bed. Please confirm the CO2 and air supply at quotation.

Frequently Asked Questions
What liquid is used?
An alkaline liquid fed as a falling film on the column wall.
Why use a wetted wall column?
The film area is known, so mass transfer coefficients can be worked out directly.
Which flows are measured?
Liquid feed, air and CO2, each on a rotameter.
