The A-train main air compressor is about 25,000 horsepower and delivers almost 9 million standard cubic feet per hour of compressed air needed for the air separation unit, an important piece of equipment necessary to operate the Great Plains Synfuels Plant. 

Repairs to the oxygen plant A-train main air compressor at Dakota Gasificaton Company's Great Plains Synfuels Plant are complete after a trip caused by high compressor vibrations occurred on Sept. 1.

Engineers at the Synfuels Plant determined the compressor rotor suffered a blade failure and employees worked around the clock to replace the compressor rotor. The compressor was brought back online Sept. 12.

Findings and recommendations from the root cause analysis will be reviewed and corrective actions will be put in place in an effort to mitigate the likelihood of experiencing a repeat failure in the future.

Each of the compressors are about 25,000 horsepower and deliver almost 9 million standard cubic feet per hour of compressed air needed for the plant's air separation unit. It is an important piece of equipment necessary to operate the Synfuels Plant.
