What action should an operator take to restore normal operation after slugging occurs in a compressor?

To restore normal operation after slugging occurs in a compressor, shutting down the compressor and notifying management is the correct action. Slugging refers to the flow of liquid or heavy particulates into the compressor, which can cause severe damage or inefficiencies. When slugging occurs, the compressor is not operating under its intended conditions, potentially leading to mechanical failure or unsafe operating conditions.

Shutting down the compressor prevents further damage and allows for a thorough assessment of the situation. Notifying management is crucial as it prompts the appropriate maintenance and operational evaluations to address the issue properly. It's essential to assess the cause of slugging, whether it is due to upstream issues, improper operating procedures, or equipment malfunction, to prevent recurrence.

Other options involve actions that may exacerbate the problem or delay proper intervention. Increasing power or reducing load does not address the underlying issue of slugging and may place additional strain on the compressor. Simply notifying maintenance without proper shutdown procedures could lead to damage that may turn into a more severe situation if the compressor continues to run.
