CB&I was awarded a contract from BASF for the engineering, procurement and construction management of a new butadiene extraction plant in Antwerp, Belgium.

The contract, which is valued in excess of $50 million, is an essential part of the total BASF investment amount, which will be in the high double-digit million euro range, the companies said.

The plant is scheduled to start up during 2014.

This award builds on CB&I’s existing relationship with BASF as licensor of its butadiene technology, according to company officials.

Butadiene is a raw material that can be used to produce synthetic rubber, among other applications including paper chemicals and plastics production.
