Evonik triples isobutene capacity in Antwerp - now on stream

ERJ staff report (DS)

Antwerp, Belgium --Evonik Industries has started up a new facility to

produce high-purity isobutene at its site in Antwerp (Belgium). The new

plant can produce up to 110,000 metric tons isobutene p.a. and forms part of the site's

integrated C₄ production platform.

The investment has tripled Evonik's

production capacity for isobutene, which is used, for example, for butyl

rubber for applications such as inner liners in

tyres.

Isobutene is produced by splitting the anti-knock agent MTBE using a

new process developed by Evonik. This new process is particularly

environment-friendly and resource-efficient: Complex heat integration in

the facility minimizes energy consumption.
