Gas Absorption Column Manufacturer,Supplier and Exporter in India
Product Code : EL-TWL-11765
Quick Answer: The Gas Absorption Column is a floor-standing rig on a painted steel frame that measures air pressure differential against air flow at different water flow rates and shows the flooding point. A gimbal-mounted glass wetted wall column fed with deoxygenated water, with oxygen probes at inlet and outlet, shows oxygen absorption, and CO2 absorption into caustic soda solution can also be run.

Key Features
Painted steel floor-standing framework carrying all components.
Glass wetted wall column with water inlet and outlet sections, gimbal mounted so it can be set accurately vertical.
Deoxygenating column of similar size beside it, where water is sparged with nitrogen.
Control console with flow meters, pump controls and an oxygen analyser.
Two housings with oxygen probes for water entering and leaving the column, read in rapid succession.
Integral diaphragm air pump; water stored in a rear tank, pumped from the base and recycled.

About This Product
Water is first sparged with nitrogen in the deoxygenating column, then enters the top of the wetted wall column while air is pumped into its base. As the air rises it gives up oxygen to the water, and dissolved oxygen is measured as the water goes in and comes out. The same equipment is used to plot air pressure differential across the column against air flow rate at several water rates and to note the flooding point.
Frequently Asked Questions
Why is the wetted wall column gimbal mounted?
So that it can be set accurately vertical. The glass column has its own water inlet and outlet sections.
How is oxygen transfer measured?
Two housings between the columns hold oxygen analysis probes that monitor the water entering and leaving the absorption column, so inlet and outlet dissolved oxygen can be read in rapid succession on the console's analyser.
What gases are used?
Nitrogen sparges oxygen out of the water in the deoxygenator, air is pumped up the column, and an air-CO2 mixture is used for absorbing carbon dioxide into caustic soda solution.
