LSB Industries Inc. today announced that its Pryor, Okla. chemical facility is expected to resume production in December 2013 after being taken out of service during October 2013 to perform unplanned maintenance and to improve equipment reliability. LSB previously announced that the Pryor facility was expected to be returned to production in November 2013, however, as the work progressed, the scope of the repair and upgrade became more extensive, resulting in a longer period of downtime than initially anticipated. The company plans to issue an update when the facility is returned to full production.
