CAGC Computer Controlled Gas Absorption Column.

The gas absorption column( CAGC) is an unit designed for studying hydrodynamics and absorption processes in packed columns. The installation absorbs CO2 from an air mixture into a aqueous solution 2 flowing down the column.
This unit is mounted on an anodized aluminium rigid structure, with wheels for mobility.
Main metallic elements in stainless steel.

Packed column consists of a glass cylindrical column of 1400 mm of height and 75 mm of internal diameter. This column is filled with Raschig rings of 8mm diameter. It includes glass ends for inlet and outlet of gases and liquids and for sample points.
Liquid circuit ( water) and gas circuit ( air and Co2) .
The liquid, that is stored in a PVC glass tank ( 40 litres capacity) , is impelled towards the column with the help of a centrifugal pump ( maximum flow rate: 540 l./ h.) .
The water flow that arrives in each moment to the column is measured with a flow sensor.
Water flow is controlled by PID control.
The liquid feeds to the column through its upper end via one glass diffusion shower that assures an uniform distribution in the filler.
After crossing the column, the liquid effluent is returned to the storage tank through a PVC conduit with hydraulic seal ( to avoid possible gas leaks) in which there are a control flow valve and one sampler.
3 Compressor ( blower) provides a maximum flow of 6 m / h and a maximum pressure of 1bar.
The gas ( CO2 or ammonia) is supplied by a cylinder, type bottle. ( Not supplied with the unit) .
The both gas flows are measured by sensors.
Differential pressure sensors. This pressure can be measured in two different parts, botton-middle and middle-upper of the column.
Mixing system of 2 gases streams.
A measuring of CO2 equipment, that allows to determine the concentration of this gas in the currents
originating from the upper and cental parts of the column. It is formed by: A glass syringe of 100 ml capacity, dedicated to extract the specific quantities of a sample to be analysed.
Two glass tanks located at different heights and interconnected. They contain an aqueous solution of KOH, in which the contained CO2 will be absorbed in the sample of gas to analyze.
3 way-valves to direct the gaseous currents during the analysis process.
Connection elements.
Rapidity and facility to replace parts of the unit, in case of failure or braking.
There are transparent elements allowing better visualization of the process.
