Pryor NH3 plant returns to production
LSB Industries Inc. today announced that its Pryor, Okla. chemical facility has commenced operations at its principal ammonia plant at near design rates. On Nov. 21, 2012, LSB announced that the Pryor facility had stopped production to install a replacement ammonia converter and to perform unplanned maintenance. LSB says that work has been successfully completed.
During the outage, with the support of third party professionals, the Pryor facility also undertook extensive programs to review and update operating procedures, to improve mechanical integrity and reliability, and to test soundness of piping and equipment. LSB said the outage at Pryor was longer than originally anticipated due to mechanical issues which arose after initial start-up requiring repairs, along with calibration of new control equipment.
