IMS Membranes

The Innovative Membrane Systems (IMS) product line is extremely robust, cost-effective, and diverse. This is part of the reason why the IMS manufacturing process is the world's leading technology for aerospace applications. In addition to aerospace inerting, the IMS process enables the use of many different membranes, materials and product geometries to serve a diverse set of applications ranging from air dehydration for Navy ships, to high pressure helium recovery from geologic natural gas.

How does the membrane technology work?

The separation process relies on partial pressure differences across the membrane. Mixed gases pass through the hollow polymer fibers at different rates. Fast gases, such as hydrogen or helium, permeate the membrane quickly. Slow gases, like nitrogen or methane, remain trapped under high pressure. This process selectively enriches the desired target gas. The entire separation system operates reliably with no moving parts.

What are the main economic benefits?

The systems require virtually no maintenance because they do not require any moving parts. In addition, minimal capital expenditure to install. Operating expenses are kept very low due to high efficiency. The highly productive, compact footprint saves valuable installation space. Customers often experience a rapid return on investment.

Which industries use these membrane solutions?

The aerospace industry uses them for aircraft fuel tank protection. The Oil and Gas sector uses them for carbon dioxide removal and pipeline purging. Petrochemical facilities use them to recover hydrogen and adjust syngas ratios. The mining industry relies on them to prevent spontaneous coal fires. The biogas industry uses them to upgrade biogas into renewable natural gas. Our membranes are also used to recover helium from well gas and to increase CO2 recovery in carbon capture solutions such as CRYOCAP™.

How do the membranes improve industrial safety?

Membranes provide a continuous, on-site supply of nitrogen gas. This nitrogen acts as an inerting blanket in dangerous environments. In aviation, it displaces flammable fuel-air mixtures to prevent ignition. In coal mines, the nitrogen stops low-temperature oxidation to extinguish fires. Industrial facilities use them to protect storage tanks and purge pipelines. Ultimately, this creates a much safer working environment.
