Braskem, Ardent Advance Breakthrough Olefin Separation Technology

Braskem, a global market leader and pioneer producer of biopolymers on an industrial scale, and Ardent Process Technologies have completed a joint development program for an innovative olefin-paraffin separation technology, marking a significant advancement in polyolefin production efficiency.

The collaboration, which began in November 2020, centered on the development and testing of Ardent’s Optiperm membrane technology at a dedicated demonstration unit within Braskem's facilities. Optiperm technology helps polypropylene plants recover valuable propylene from purge gas streams — increasing production by 8–13% without the need for major capital projects. Unlike conventional separation methods, Optiperm uses advanced facilitated transport membranes that separate olefins from paraffins based on chemistry, not extreme temperature and pressure. The result is a compact, modular, electrified system that installs easily during scheduled turnarounds.

Braskem to commercial propylene recovery technology

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."
