Membrane Module Pilot Unit used for Olefin Separation Technology Development

The collaboration, which began in November 2020, centered on the development and testing of Ardent's Optiperm^TM membrane technology at a dedicated demonstration unit within Braskem's facilities. The rigorous development program has satisfactorily met key performance metrics, including membrane efficiency, durability, and operational stability.

"The successful pilot program demonstrates the tremendous potential of this technology to revolutionize olefin paraffin separation processes," said Bill Charlton, the COO of Ardent and leader of this project. "We are excited to move forward with Braskem towards full commercial implementation."

Following these promising results, Braskem has confirmed its intention to implement this groundbreaking technology across commercial facilities. Engineering and design work have already commenced for the first commercial installation.

"This technology represents a significant step forward in our commitment to innovative and sustainable solutions," said Gus Hutras, Global Process Technology Director at Braskem. "The successful pilot results align with our vision of transforming the chemicals and plastics industry through innovation while advancing our goals toward carbon neutrality. We're excited to move this breakthrough technology into commercial implementation."
