We are thrilled to announce that our membrane has been selected for one of the most exciting developments in the beverage world, Nitro Coffee. Our partners, JoeTap and Micro Matic are cranking out countertop nitro systems designed for convenience stores, restaurants, coffee shops, hotels, and offices.
These membrane systems have an increased safety and convenience factor when compared to nitro coffee systems that use nitrogen cylinders. There are no repetitive tank changes or lugging of heavy cylinders. The membrane unit generates nitrogen on the spot with a ‘set it and forget it’ mentality for system operators.
The best part about being involved in nitrogen applications like nitro brew coffee is that they are truly fun and innovative concepts. Nitro brew coffee is delicious and has even been compared to drinking a Guinness. Infused nitrogen enhances the silky smoothness in the beverage and there’s an added entertainment factor of experiencing the eye-catching cascade effect.
An interview with a PRISM Membranes employee.
Which PRISM Membrane products are PED certified?
All six of the PB biogas upgrading membrane separators are certified to the European PED (Pressure Equipment Directive) requirements.
How do the Prism PB membrane separators differ from competing biogas membrane products?
Some of our competitors offer biogas upgrading separators which are not PED certified. One company, who had previously used our competitor’s membrane product, was required to build their own pressure vessels around the units for secondary containment. This was an expensive inconvenience for the company, which was even more evident when the system included 80 membrane separators. Choosing the PED certified Prism PB membrane separators will eliminate the need to build expensive secondary containment pressure vessels.
How does Air Products obtain the certifications?
In the beginning developments of our PB biogas membrane separators, our engineering team researched the PED requirements for pressure vessels/flammable gases and designed the membrane to meet the directive. The lightweight aluminum shell was selected over stainless steel because it provides the pressure safety element while also allowing the membrane unit to be installed into compact locations without lift-assist equipment. The PED certification requires a series of internal tests and documentations as well as design and sub supplier audits.
Our Air Products Norway office was recently nominated for the ONS Innovation Award 2016. The focus of this recognition centered on the team’s revolutionary membrane system concept for CO2 capture.
“Among 130 entries, we are extremely proud to be selected as one of five finalists. We are thrilled to be recognized as an innovative company that works to solve one of the major problems connected to a deteriorating climate and global warming.” said Tom Cantero, Managing Director of Air Products Norway.
A pilot membrane system for CO2 capture is already in operation at a cement factory in Brevik, Norway. Future large-scale developments are underway.
Compressed air membrane dryers are typically smaller and lighter than desiccant and deliquescent dryers. More importantly, air dryer membranes require much less maintenance and attention than the other methods of dehydration. Check out our air dryer technology comparison below to learn more about the simplicity of membrane dryers.
Prism Membrane separators are known for their reliability and longevity. Proper operation can help extend the membrane life even longer. Here are two failure modes for membrane separators and what you can do to prevent them:
1. Contamination- liquids or solid particulates from the feed gas plug the membrane fiber and reduce membrane performance.
Avoid contamination by selecting and maintaining the proper upstream filters. Strategic system design and process control also help.
2. Broken Membrane Fiber-the hollow polymer fiber cracks and results in a loss of product or excessive air consumption.
Avoid broken fibers by operating the membrane within its temperature and pressure limits. Inserting fittings too deep, long term ozone exposure, and excessive cycling may cause fiber breakage too.
Prism Membrane customers are encouraged to utilize free technical support to achieve a successful system design which minimizes premature membrane failure.
Nitrotherm Spray by Eurosider is a patented coating application technology which utilizes our Prism Membrane separators. These innovative systems use nitrogen as the carrier gas along with controlled temperature settings to achieve flawless coating applications. The systems reduce wasteful over-spraying and decrease application time.
In a recent article, Eurosider discussed the success of Nitrotherm Spray systems in the wood furniture market. The application thrived in furniture manufacturing facilities in Europe and is now expanding into the United States. Automotive painting is another successful industry where the Nitrotherm Spray systems flourish. To learn more about Eurosider’s innovative membrane systems, visit their booth at the Automechanika, tradeshow this week in Frankfurt, Germany.
We offer two options for procuring Prism membrane separators.
1. Buy a complete membrane system, engineered by Air Products
We offer turnkey membrane systems for large scale nitrogen production, shipboard gas generation, and process gas applications. Many of these systems are located in oil refineries, petrochemical plants, and ammonia production plants. Learn more about our membrane systems here.
2. Buy individual membrane separators and build your own systems
This is considered our “OEM” style of business. We partner with membrane system builders who have innovative applications for nitrogen, biogas, oxygen enriched air, and air dehydration. We supply the appropriate membrane, technical support, and preferred pricing and lead times while the OEM builds and sells the systems to end users. Learn more about our OEM partnerships and if you would like to use our membrane technology in your gas systems, please contact us here.
