Which towers are widely used for gas absorption?
Packed columns are most frequently used for gas absorption (and are used to a limited extent for distillation) wherein the liquid is dispersed in the form of film and the gas flows as a continuous phase.
What is an absorber tower?
A long vertical column used in industry for absorbing gases. The gas is introduced at the bottom of the column and the absorbing liquid, often water, passes in at the top and falls down against the countercurrent of gas. The towers are also known as scrubbers.

What is the name of column or tower used in the absorption process?
The solid to which the liquid or gaseous component attached itself is called the adsorbent. The device in which the adsorption process takes place is usually called an adsorption tower, adsorption column or adsorber.
How does a packing tower work?
Packed towers work by providing a large amount of surface area per unit volume to facilitate the liquid-vapor mass transfer. As the liquid phase flows through the tower, the vapor and the liquid are in continuous contact on the surfaces of the packed bed, differing from the stepwise contact of tray towers.
What is packed tower used for?
Absorption Towers Conventional packed towers are used for different mass transfer operations such as distillation and absorption. The tower consists of a vertically positioned cylindrical shell filled with packing.
What is produced in absorption tower?
The product formed in absorption tower during the manufacturing of sulphuric acid in contact process is H2S2O7, as shown in the below reaction.
What is the difference between column and Tower?
Generally, pillar and column are synonymous (they both hold something up). A tower usually has a means of going inside, climbing stairs or a ladder to the top. It can be free-standing or attached to another building.
What are packed towers used for?
Packed towers are used increasingly in a variety of applications in the chemical process industries. The reasons for this are an increase in the availability of design information, the evolution of higher-capacity and higher-efficiency mass-transfer packings, and improvements in distributors and support plates.
What are the parts of packed tower?
Components of packed tower
- Tower body.
- Tower packings. Structured packings. Random packings. Demister pads.
- Tower internals. Liquid distributor. Packing supporting grid. Packing hold-down grid. Liquid redistributor. Gas distributor.
What is packed tower aeration?
The aerator column is filled with polypropylene packing media, designed for either random packing or structured packing. The packing provides a large air/water contact area to strip volatile compounds from water.
