LSB Industries Inc. reported Oct. 24 that its Pryor, Okla., nitrogen facility went offline in October and is not expected back up until mid-November. The plant which can produce up to 700 st/d of anhydrous ammonia and 325,000 st/y of UAN, is a key economic driver for the company. LSB explained that the facility went down to perform unplanned maintenance which was indicated by newly-installed diagnostics equipment. LSB also sought to improve equipment reliability. Since the shutdown, LSB said the scope of the maintenance activities have increased as mechanical issues and opportunities for plant performance improvements were identified.
