What is Gas Absorption Tower?

Gas Absorption Tower is a device used for gas absorption operation. Its main function is to make certain components in the gas absorbed by the liquid through gas-liquid contact, so as to achieve the purpose of purifying or separating the gas. This equipment is widely used in many fields such as chemical industry, environmental protection, metallurgy, etc.

The working principle of the gas absorption tower is based on the mass transfer process between the gas and liquid phases. In the tower, the gas is usually dispersed in the liquid phase in the form of bubbles, or the liquid phase contacts the gas phase in the form of droplets, films, etc., and the absorption efficiency is improved by increasing the gas-liquid contact area and extending the contact time. According to the different contact forms of the gas-liquid phase, the gas absorption tower can be divided into plate tower, bubbling absorption tower, stirred bubbling absorption tower, ejector, venturi, spray tower, packed absorption tower and falling film absorption tower.

Among them, the bubbling tower is a commonly used gas-liquid contact reaction equipment, which forms bubbles by passing the gas through the liquid layer, thereby achieving full contact and mass transfer between gas and liquid. The bubble tower has the advantages of simple structure, convenient operation and high mass transfer efficiency, and is widely used in the oxidation reaction of various organic compounds.

In general, the gas absorption tower is an important chemical equipment, which is of great significance for improving gas purification efficiency, protecting the environment and promoting industrial development.
