Features:
Tesca Gas Adsorption Column is designed to demonstrate & analyse principle of gas adsorption in unit operation of chemical engineering. The gas adsorption unit works by continuously passing a gas mixture through a fixed bed of porous solid materials known as absorbents. Adsorption takes place primarily on the walls of the pores or at specific sites inside the porous particles. Separation occurs due to differences in molecular weight, shape or polarity causing some molecules to be held more strongly on the surface than others because the pores are too small to admit larger molecules.

The system is fully instrumented with oxygen composition, temperature sensors, pressure gauges & flow meters.

The unit comes complete with two packed columns, a bottom cooler, a feed vessel and a circulation pump. One absorption column is designed to absorb CO2 from an air/CO2 mixture in to water flowing down the column. The second column of exact dimensions is designed to desorb CO2 from the water product from 1st column into supplied air.

All electronic components are fitted on the main control console for ease of operation and console. The flow connections are fitted with full stainless steel piping and control valves for configuration control.
