Liquid Deaeration for Corrosion Control and Reduced Chemical Usage

Liqui-Cel® membrane contactors have been used for over 20 years to remove dissolved gases from liquids or add gases to liquids. These deaeration devices are capable of removing O2 to < 1ppb and CO2 to < 1ppm. Liqui-Cel® liquid degassers are designed to tolerate high pressures/temperatures and are capable of processing flow rates from 5ml/min to hundreds of m³/hr.

Liqui-Cel® membrane contactors have been used for over 20 years to remove dissolved gases from liquids or add gases to liquids. These deaeration devices are capable of removing O2 to < 1ppb and CO2 to < 1ppm. Liqui-Cel® liquid degassers are designed to tolerate high pressures/temperatures and are capable of processing flow rates from 5ml/min to hundreds of m³/hr.

Dissolved gas removal for corrosion control

In the power-generation industry, limiting the amount of dissolved O2 and CO2 that enters a plant is essential to protect costly systems and components, such as boilers and piping. These components are vulnerable to corrosion because of dissolved gasses that are carried in through the feed water.

Dissolved gas removal with membrane contactors

In order to protect many metal systems’ components in the plant, dissolved oxygen and carbon dioxide that can negatively impact boiler performance and corrode metal must be removed.

Liquid degassing equipment

Liquid degassing can be accomplished using various methods, including chemical injection, vacuum towers, and/or forced draft deaerators, but these older technologies do not provide the same level of dissolved gas control. A typical vacuum tower can only achieve oxygen removal down to 7ppb, whereas Liqui-Cel® can remove down to < 1ppb.

The amount of CO2 removed by a typical forced-draft deaerator is typically 10ppm, which is much less than membrane contactors can achieve. Membrane contactor systems can be sized to remove dissolved CO2 down to 1ppm. Liqui-Cel® contactors are compact, efficient and more economical to operate.

Membrane degasifiers

Chemical injection does not use the large footprint of a vacuum tower or forced-draft deaerator, but has its own set of problems. The use of chemicals will, over time, place excess deposits on the metal surfaces in the boiler and piping throughout the plant. As deposits accumulate, the boiler has to be shut down for cleaning; this process is known as a blow down. Using more chemicals causes more frequent blow down schedules, resulting in higher operating costs.

All these problems can be easily remedied by using Liqui-Cel® membrane degasifiers, which have been field proven for over 20 years.

Gas removal and addition deaerators

Liqui-Cel® deaerators are used in many other applications. Most liquids that need gasses removed or added can benefit from a Liqui-Cel® membrane contactor system.
