Advanced Dissolved Gas Control

  • 3M™ Liqui-Cel™ Membrane Contactors provide an efficient method for dissolved gas control and degassing liquid within a compact design. Capable of adding gases to, or removing dissolved gases and bubbles from compatible liquid streams, these gas transfer devices utilise hollow fibre membrane technology that may help facilities around the world improve operating efficiency, performance and protect product quality.

Dissolved gas control with 3M™ Liqui-Cel™ Membrane Contactors – product categories

  • 3M™ Liqui-Cel™ EXF Series Membrane Contactors

    For efficient gas removal or addition, 3M™ Liqui-Cel™ EXF Series Membrane Contactors utilise a microporous hollow fibre membrane, inside a device designed to enhance flow dynamics and take full advantage of the large membrane surface area. With proper system design, ultra-low levels of dissolved gas can be achieved.

  • 3M™ Liqui-Cel™ SP Series Membrane Contactors

    Commonly used for gas removal and debubbling liquids with low surface tensions, 3M™ Liqui-Cel™ SP Series Membrane Contactors use a non-porous, gas-permeable hollow fibre. This membrane-based technology makes it possible to degas and debubble compatible solutions containing surfactants or organic solvents.

  • 3M™ Liqui-Cel™ MM Series Membrane Contactors

    3M™ Liqui-Cel™ MM Series Membrane Contactors are our smallest gas removal (debubbling) devices. These membrane contactors have a high membrane surface area. Used primarily in laboratory and analytical applications, degassing liquid with these small point of use degassers/debubblers may help to improve measurement reliability, reduce rework, and improve product quality.

3M™ Liqui-Cel™ Membrane Contactors in Industry

3M™ Liqui-Cel™ Membrane Contactors are used for degassing liquid around the world. They’re widely used for oxygen removal from water as well as carbon dioxide removal from water. They’ve replaced the vacuum tower, forced draft deaerator, and oxygen scavengers around the world for over 20 years.

  • Microelectronics and semiconductor

    Degassing liquid with 3M™ Liqui-Cel™ Membrane Contactors is common in the production of ultra-pure water to achieve the extremely low O₂ and CO₂ levels required by today’s semiconductor and flat panel display plants. Low O₂ levels help protect product yield and low CO₂ levels help maximise the efficiency of electrodeionization and ion exchange processes.

    3M™ Liqui-Cel™ membrane contactors also enable precision control of the dissolved gases in ultra-pure water and other compatible wet bench processes fluids.

  • Beverage production

    There are many applications in the beverage industry that require the addition or removal of O₂, CO₂, nitrogen, and alcohol compounds.

    3M™ Liqui-Cel™ Membrane Contactors are the ideal technology solution capable of handling the multiple gas removal and gas addition requirements in the beverage industry.

  • Power and steam generation

    Power plants generating steam balance cost, efficiency and reliability with environmental considerations while supplying energy to the world. Degassing water systems plays a critical role in the process that generates the energy used to heat and cool homes and businesses while protecting vital capital equipment. 3M™ Liqui-Cel™ Membrane Contactors remove dissolved O₂, CO₂, and volatile gases to industry-leading levels at low temperature and without requiring steam. With their chemical-free membrane technology, 3M™ Liqui-Cel™ Membrane Contactors can help enhance the performance of water treatment systems and reduce the risk of downtime. They offer a cost-effective, easy-to-use and efficient gas removal solution for power plants and other plants with boiler water systems for producing steam.

  • Oil and gas

    3M brings its proven reliability and performance to refineries, offshore platforms, FPSOs (floating production storage and offloading) and other areas in the oil and gas industry. Oil and gas customers are quickly learning about and adopting membrane gas transfer technology to take advantage of the same benefits that other industries have been realising for years. Common gas removal applications include boiler feedwater deoxygenation, CO₂ removal in ion exchange, and water flooding in offshore environments.

  • Ink jet printing, inks and coatings

    Degassing and removing bubbles from liquid such as inks and other compatible fluids can improve yields, prevent defects and enhance operational performance. Inkjet printers often degas inks to prevent reduce imperfections in print quality and prevent nozzle misfires or jet-outs.

    3M™ Liqui-Cel™ SP Series Membrane Contactors are widely used for gas removal and dissolved gas control in inks, coatings and other fluids with low surface tensions where gasses in production lines negatively impact the process.

  • Pharmaceutical

    The pharmaceutical industry requires a continuous source of purified water with a conductivity of < 1.3 µS/cm. To achieve this level of purity, RO followed by EDI technology is commonly employed. However, the presence of free CO₂ may reduce EDI efficiency.

    Historically, chemical dosing with NaOH or forced draft technology was used to reduce the CO₂ load. Today, 3M™ Liqui-Cel™ Membrane Contactors can be used as a compact, chemical-free alternative to degassing liquid, operating in closed systems which may help reduce the risk of contaminants from entering the purified water stream.

  • Laboratory and analytical

    Gas removal can significantly improve accuracy – dissolved gases can interfere with instrument readings and could alter the composition of solutions for analysis. With 3M™ Liqui-Cel™ Membrane Contactors water used in laboratory settings can be effectively degassed, improving measurement reliability and overall lab efficiency. Optical sensors in quality control systems can also read bubbles as defects resulting in product waste.

    The small footprint of 3M™ Liqui-cel™ MM Series Membrane Contactors are easy to integrate into analytical devices or into laboratory DI water supply systems. EXF and SP Series can be can be used for larger flow rates or compatible solutions with low surface tensions containing surfactants, organics or other solvents.
