What is the function of a degasifier/decarbonator?

A degasifier or decarbonator primarily serves to eliminate dissolved gases from water, which is a crucial function in water treatment processes. The presence of dissolved gases, particularly oxygen and carbon dioxide, can lead to corrosion and other issues within boilers and other parts of steam systems. By removing these gases, a degasifier helps to protect equipment and improve overall efficiency.

For example, in a steam boiler system, dissolved oxygen can cause pitting and corrosion of the metal components, leading to premature failure. Carbon dioxide can combine with water to form carbonic acid, which can also contribute to corrosive conditions within the boiler. By effectively reducing these dissolved gases, the degasifier ensures the water is treated to a condition that is conducive to safe and efficient operation.

This function of eliminating dissolved gases is essential for maintaining the integrity of the water and the systems it supports, thereby enhancing operational longevity and performance in various industrial applications.
