This equipment is for demonstration of gas absorption principles.

The unit consists of two packed absorption columns, one on top of another. The two columns are held together by steel frame and are packed by Raschig glass rings. A centrifugal pump draws a liquid from a feed tank underneath the column and delivers to the top of the column where it falls down through the packing and to the storage tank. Flow rate is indicated on a variable area flow meter.

A gas to be absorbed such as carbon dioxide is drawn from a pressure cylinder through a flow meter and is mixed with an air stream supplied through an air blower. Air flow rate is measured by a flow meter. The mixed gas enters the column at the bottom of the column and rises up to the top.

Pressure tapping points and gas sampling points are provided at the bottom, middle and top of the column to measure pressure drops by manometer and differential pressure gauge. Carbon dioxide content is determined by a Hempel apparatus (optional). All instruments are mounted on a panel.

Instruction manual is also included.
