LSB Industries Inc. reported late Jan. 29 that additional repairs are required at the anhydrous ammonia plant at its Pryor, Okla., chemical facility. LSB said it is diligently working to complete the repairs and is performing additional maintenance while the plant is down. The company said it will update the market when the plant returns to production.
On Jan. 8, LSB reported that the plant went back down after a brief restart. At the time, LSB reported excessive vibrations in the second stage of the compressor. It said the second stage compressor was sent to Sulzer Turbo Services’ Houston, Texas laboratory for high speed testing and diagnosis. At that time, LSB was hoping the plant would be back up by the end of January. On Dec. 30, 2013, the plant restarted after having been down most of the fourth quarter.
