Gas-Liquid Absorption Column Manufacturer,Supplier and Exporter in India
Product Code : EL-MLE-13260
Jlab Export is a leading Gas-Liquid Absorption Column Manufacturer,and suppliers in India
Gas-Liquid Absorption Column (code EL-MLE-13260) is a floor-standing teaching unit in which carbon dioxide is absorbed from an air–CO2 mixture into water flowing counter-current through a packed column. Flowmeters for water, air and CO2, gas analysis equipment and temperature-controlled water let students follow both the mass transfer and the column hydraulics. This CO2 absorption unit is manufactured by JLab in Ambala, India.

Column Hydraulics and the Flooding Point
Water enters at the top and trickles down over the glass packing while the gas rises through the spaces between the pieces, so the leanest gas meets the freshest water at the top of the column. The manometers give the air pressure differential across the column as the air flow is raised at several water flow rates. Pressure drop climbs with both flows until the flooding point, where the liquid can no longer drain against the rising gas and builds up in the packing.
Absorbing into Water, Caustic Soda and a Falling Film
Absorbing CO2 into caustic soda solution instead of water shows chemical absorption: the gas reacts with the hydroxide in the liquid, so the solution takes up CO2 faster than plain water does.
The unit also carries a gimbal-mounted glass wetted-wall column, set truly vertical so the water film runs evenly, with a deoxygenating column beside it. Water is first stripped of oxygen by sparging with nitrogen, then runs down the wetted wall while a diaphragm pump drives air up the column. Probes at the water inlet and outlet measure how much oxygen the film has absorbed, and the water drains back to the storage tank for reuse.
