At Tessenderlo in Belgium, Worley will provide front-end engineering and design (FEED) services for Trinseo’s proposed chemical recycling plant. The contractor completed pre-FEED services on the project last year.

The facility, which will process 15,000 t/y of recycled PS flake, will use gasification technology licensed from Synova to depolymerize post-consumer PS waste into pure styrene. The recycled styrene will be used to make new PS and/or styrene derivatives, including ABS and SAN.

Construction is planned to start at the end of 2022 – a start-up date has not been given. Trinseo said the plant is the first of its kind on an industrial scale. 

In separate news, Worley has been contracted by Green Energy Oman (GEO) to support its low-carbon fuels project. The contractor is providing concept feasibility study services to develop and challenge GEO's defined green hydrogen energy project. This includes optimizing around 25 GW of wind and solar generation, transforming the renewable energy through electrolysis into green hydrogen, and producing, storing and exporting green ammonia.

Overall, the project aims to produce more than 1.8 million t/y of low-carbon green hydrogen that can make up to 10 million t/y of green ammonia, supporting both the local economy and global market by exporting the ammonia to help other countries decarbonize their economies.

“Hydrogen has the potential to decarbonize hard to abate sectors where there’s no obvious alternative,” said Hans Dieter Hermes, Worley’s vice president of clean hydrogen. “This project enables Oman to use their natural resources to produce green fuels for self-use and export, and supports our purpose of delivering a more sustainable world.”

Worley will lead the work from its Muscat office, with support from its European Centers of Excellence.

The GEO project consortium comprises OQ, the Sultanate of Oman’s global integrated energy company, InterContinental Energy, a leading dedicated green fuels developer, and EnerTech, a Kuwait government-backed clean energy investor and developer.
