Ardent’s facilitated transport membranes unlock powerful separations

Facilitated transport membranes (FTMs) use embedded carrier molecules to selectively transport target molecules across the membrane. Ardent’s innovative system design harnesses the power of FTMs to make them stable, operable, and performant for industrial-scale chemical separations.

Selective separation

Ardent’s FTMs provide excellent selectivity, allowing for precise separation of target compounds while rejecting unwanted components.
high flux rates icon

High flux rates

Combining the facilitated transport mechanisms with a compostie membrane design significantly enhance flux rates across the membrane, leading to increased throughput and efficient use of performant materials.
low pressure icon

Low pressure operation

Ardent’s membranes can operate at low pressure, making them more energy-efficient and significantly reducing the need for large balance of plant.
humidification system icon

Patented humidification

Ardent’s proprietary humidification system ensures the membrane is properly humidified with a continuous process that does not require regeneration, essential for field performance of any facilitated transport membrane.

Modeling and system design

While membranes can unlock power operating windows, proper system design catapults them from interesting lab data to efficient process units. Ardent’s proprietary models ensure optimal system design for every system and power our control systems.

Optiperm™ delivers on
the promise of facilitated transport membranes

Ardent’s advanced Optiperm™ membranes use proprietary materials and coatings for optimal permeance and selectivity to reduce greenhouse gas emissions and/or separate olefins from paraffins.
Optiperm™ Carbon Membrane

carbon capture

Optiperm™ Carbon captures greenhouse gas emissions by passing flue gas streams through Facilitated Transport Membranes that separate the CO2 from the other gasses in the stream.

Optiperm™ Olefins Membrane


Optiperm™ Olefins uses facilitated transport to pass olefins through the membrane while leaving the paraffin behind. This is in contrast to the 70-year-old incumbent technology (distillation), which uses difference in boiling points and incurs high operational and capital penalties.

What makes Ardent’s membranes different from other membranes?
Chevron arrow down
Rather than relying on pressure or temperature to accomplish separation, Ardent’s cutting edge Facilitated Transport Membranes rely on the chemistry of the membrane itself, significantly reducing the need for compression or large balance of plant. Combined with a rugged polymer backbone, Optiperm™ membranes are more energy-efficient, easier to operate, more poison resistant, and longer lasting than other membrane solutions.
Are new prototype membranes all Ardent has to offer?
Chevron arrow down
No, while Ardent has spent years perfecting our membrane chemistry, we also have 20+ years of membrane manufacturing experience. Ardent has capabilities for chemistry, membrane prototypes, product development, system design and engineering. We cover the entire lifecycle of the membrane product.
I heard FTMs need water? How do you handle this?
Chevron arrow down
Like all FTMs, Ardent’s Optiperm™ membranes require humidification. Ardent has developed a proprietary humidification system that ensures the membrane is properly humidified at the module level without adding humidification unit operations. Our system has been demonstrated commercially in the olefin-paraffin application.
Every plant is different with different streams and different feed impurities – how does Ardent handle this?
Chevron arrow down
Ardent offers a flexible platform design to meet the needs of different streams within your plant. Different feed pre-treatment options can easily be added to remove impurities such as hydrogen and aluminum.
Does Ardent make only one kind of membrane?
Chevron arrow down
Ardent provides both pervaporation (legacy) and facilitated transport membranes as part of our solutions. Ardent also has experience in different form factors of membranes: flat sheet, hollow fiber, and spiral wound.
Do you have manufacturing capability?
Chevron arrow down
Yes! Ardent produces 1000+ membrane units a year of varying sizes and applications. We have experience taking membranes from the lab bench to full commercial scale.

Why facilitated transport?

By: Richard NOBLE
Unchanged for the last 80 years, incumbent technology like distillation columns. and absorption towers cannot deliver further benefits for existing separations. Facilitated transport membranes have been considered the “holy grail” of membrane solutions. Sought after for their powerful selectivity and high flux, they have been viewed by academia as the key to using membranes for highly impactful gas separations
