New Isobutene Plant in Antwerp
Evonik Industries has inaugurated a new facility in Antwerp, Belgium, dedicated to producing high-purity isobutene. The plant, which required an investment of tens of millions of euros, has an annual production capacity of 110,000 metric tons. This development significantly boosts Evonik’s isobutene production capabilities, tripling their previous capacity.
Advanced Production Process
The isobutene is produced by splitting the anti-knock agent MTBE using a newly developed, environmentally friendly process. This method features complex heat integration to minimize energy consumption and employs an innovative catalyst free of heavy metals, ensuring optimal use of raw materials and minimal by-product generation.
Applications and Uses
Isobutene is a crucial component in various industries. It is used in the production of butyl rubber for automotive tire inner liners, which require low air permeability. Additionally, it is a key ingredient in the manufacture of plastics, antioxidants, fine chemicals, and polyisobutene, which serves as a starting material for lubricants, fuel additives, adhesives, and sealants.
Integrated C4 Production
Evonik’s integrated C4 production complex in Antwerp is one of the leading technology platforms globally. The facility processes all components of crude C4, a by-product of ethylene and propylene production, into valuable chemicals such as isobutene, butadiene, MTBE, butene-1, oxo-alcohols, and plasticizers. This integrated approach enhances efficiency and flexibility in managing product streams.
