Description:
The Gas Absorption Column has been designed to demonstrate the principles of gas absorption and to provide practical training in the operation of a gas absorption plant.
In the process of gas absorption, a mixture of gases is contacted with a liquid, for the purpose of dissolving one or more components of the gas and to provide a solution of them into the liquid.
In this a gas phase consisting of CO2 and air is introduced into the bottom of the packed column. Adjustment of their flow ratio is obtained by manual valves. A sample of the gas mixture is sent to a CO2 concentration sensor located inside the electric console, and readings of flows and percentage CO2 concentration is visible on the display screen as well as in the software.
Specification:
- An apparatus for teaching the principles of the absorption of gas into liquid, using a packed column
- Column working length is 1.4m x 80mm diameter, split into two sections
- Two electronic pressure sensors measure the pressure drop across each half of the column
- An electronically controlled submersible pump provides a liquid flow of 1-10 l/min 60l feed tank
- Water flow can be used in either recycle or one-pass operation
- Column supplied with 10mm x 10mm Raschig rings as packing material, total volume 7l. Other sizes can be used
- Centrifugal fan provides air flow up to 160 l/min
- Two electronic temperature sensors measure the air and liquid temperatures
- Electronic measurement of CO2 concentration in the air streams, measurements can be taken at the column inlet and outlet
- Sensor values displayed on an alphanumeric display on the control console
- Data logging as standard (requires PC, not supplied)
