Our strengths in styrene monomer
We are recognised leaders in styrene monomer production, technology and product stewardship and have over 40 years鈥� experience in making and supplying styrene monomer through a global manufacturing base and supply network.
Shell companies have over 40 years' experience in producing and supplying styrene monomer. Today, the Shell Group is one of the largest global producers of styrene monomer and recognised as a technology leader and supplier of product of high and consistent quality.
We have a strong global manufacturing base, with production facilities in all main regions:
- Scotford, Canada
- Nanhai, China
- Moerdijk, The Netherlands
- Al Jubail, Saudi Arabia
- Jurong Island, Singapore
Process technology
The conventional method for producing styrene monomer is the alkylation of benzene with ethylene followed by dehydrogenation to produce styrene monomer. An alternative to this is the process to co-produce styrene monomer (SM) and propylene oxide (PO) via the oxidation of propylene by ethylbenzene hydroperoxide, also known as the 'SMPO' process. Shell operates both manufacturing processes at locations around the globe.
Our key strengths:
Supply security/product quality
An integrated global manufacturing base and supply network along with a leading position in the merchant market provides reliable and consistent high quality supply to our customers.
Proven technology
A recognised leader in styrene technologies, applied to world scale manufacturing plants.
Health Safety, Security and Environment (HSSE)
Strong commitment to high HSSE standards and a leading role in industry initiatives in this area.
