•Tech Brief: Degassing Boiler Feed Water In China With Liqui-Cel® Membrane Contactors
ShenLan Environment Inc. located in Shanghai China uses Liqui-Cel® Membrane Contactors in their boiler feed water treatment systems. These systems realize lower operating costs with the added benefit of reducing the chemicals added to the boiler feed water.
Background
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.
