Degasser

Degasser

A degasser is a device used in various industries to remove unwanted gases from liquids, particularly in the field of water treatment and oil refining. It plays a crucial role in maintaining the quality and purity of liquids by eliminating dissolved gases that can cause corrosion, foaming, and other undesirable effects.

Function

The primary function of a degasser is to remove dissolved gases, such as oxygen, carbon dioxide, and hydrogen sulfide, from liquids. These gases can enter the liquid during various processes, such as water treatment, oil drilling, or chemical reactions. If left untreated, these gases can lead to numerous issues, including equipment damage, reduced efficiency, and product contamination.

A degasser typically consists of a vessel or tank with an inlet for the liquid to enter and an outlet for the degassed liquid to exit. Inside the vessel, there are various mechanisms designed to facilitate the removal of gases. These mechanisms can include trays, packing materials, or specialized membranes, depending on the specific application and requirements.

Applications

Water Treatment

In the field of water treatment, degassers are commonly used to remove dissolved gases from water sources, such as lakes, rivers, or underground wells. Dissolved gases in water can cause problems in industrial processes, such as corrosion in pipelines, scaling in boilers, or reduced efficiency in heat exchangers. By removing these gases, degassers help to improve the overall quality and performance of water treatment systems.

Oil Refining

In the oil refining industry, degassers are utilized to remove unwanted gases from crude oil or other petroleum products. During the extraction and refining processes, gases such as hydrogen sulfide and carbon dioxide can dissolve in the oil, leading to various issues, including corrosion, foaming, and reduced product quality. Degassers play a vital role in ensuring the purity and stability of petroleum products by effectively removing these gases.
