Boiler Feed Water Degassing Lowers Operations Costs and Chemical Usage

From Membrana
 

 

Proper treatment of boiler feed water is an important component of a boiler system. As steam is produced, dissolved solids become concentrated and deposit inside the boiler. This leads to poor heat transfer and efficiency reduction of the boiler. Dissolved gasses such as oxygen and carbon dioxide will react with the metal surfaces inside the boiler promoting corrosion. Degassing is an important step for protecting the boiler.

Liqui-Cel Membrane Contactors offer many advantages over forced draft deaerators, vacuum towers, and chemical treatment programs for feed water treatment. Membrane Contactors utilize microporous membranes to create 10X the surface area compared to mechanical technologies. Contactors are highly efficient, compact and can be used inline under pressure.
