Compact Membrane Systems and Braskem Start Up OptipermTM Demonstration Plant

Compact Membrane Systems , Inc. (CMS), a pioneer in membrane systems for energy transition applications and Braskem (B3: BRKM3, BRKM5 and BRKM6; NYSE: BAK; LATIBEX: XBRK), the largest polyolefins producer in the Americas, as well as a market leader and pioneer producer of biopolymers on an industrial scale, are pleased to announce that the long awaited pilot demonstration of CMS's Optiperm TM technology for light olefin paraffin separation has started up at Braskem's Marcus Hook facility.

Optiperm TM , CMS's breakthrough membrane technology, is designed to increase olefin production efficiency while  decreasing waste streams, lowering carbon emissions, and reducing total energy usage . The modular nature of membranes allows olefin recovery from small and large process streams alike, debottlenecking processes and leveraging existing infrastructure in a more energy-efficient manner. CMS and Braskem recognize that capturing olefins from unused hydrocarbon process streams is essential to decreasing environmental impact while continuing to create the chemical building blocks for plastic resins and chemical products for diverse customer segments, such as healthcare and hygiene, food packaging, construction, manufacturing, automotive, agribusiness, among others. 

Successful demonstration paves the way for the roll out of Optiperm TM , in olefins applications as well  point source carbon capture for SMRs, steel, cement and other decarbonization applications. 


This project will address the critical milestones of simultaneously producing high purity (>90%) paraffin and olefin rich streams with a multistage membrane design. The design is a replica of the design with membrane areas balanced between two stages and a full control system to meet stream purity specs. The rig itself was built by Zeton , the world's leading designer and builder of lab scale systems, pilot plants, demonstration plants and modular systems. The pilot has been deployed at Braskem's Marcus Hook facility and will be operated for a period of 500 days. "Braskem believes that investing in the advancement of technology is a leading factor in the search for a more sustainable future" says Kevin Soucy, Technology Improvements Manager, Braskem. "The successful startup of this pilot supports our commitments to the circular economy. Special thanks to both CMS and Braskem team members for completing the first step of such a complex project despite the challenges of the COVID-19 pandemic. We are very excited to continue to work with CMS through optimization and commercialization of their Optiperm TM technology."


This is the largest demonstration of the  Optiperm TM platform to date and includes commercial sized modules.  Previously , CMS has demonstrated the stability of small-scale membranes. This will be the first demonstration that includes CMS's proprietary humidification design and a full-scale commercial membrane module produced at an industrial scale manufacturing facility. Commercial membrane products will be available from CMS as early as 2023.

"The team is delighted that this pilot unit is up and running. Optiperm TM olefins technology is an important part of our industrial decarbonization portfolio, validating for our customers that CMS technology can enable their business performance and GHG reduction goals. Placing commercial scale cartridges into the field is a major milestone for us and for the planet." says CMS CEO Erica Nemser. "Braskem's vision and commitment to industry leading innovation has made this project the ideal commercial demonstration of our first generation Optiperm TM technology."


Compact Membrane Systems (CMS) is dedicated to enabling the clean energy transition and improving the efficiency of chemical processing through membrane solutions. Located in Newport, DE, CMS harnesses the power of unique fluoropolymers to provide durable and effective chemical separation solutions in the toughest environments. CMS membranes can be used independently or in conjunction with existing infrastructure to recover and remonetize streams that would otherwise be undervalued or wasted. CMS technology delivers new sources of revenue and lowers costs for process industries including petrochemicals, biogas, refining, specialty chemical and pharmaceuticals.

CMS combines innovative research with practical industry know-how to deliver modular units with lower energy usage and smaller footprints than existing separation technologies. From polymer development, to product engineering, to system design, CMS has the capabilities and partnerships to deliver projects of any size. For more information or to learn more, visit
