What must an operator do if liquid slugging occurs?

When liquid slugging occurs in a gas compression system, the operator must shut off the compressor to prevent damage to the machinery. Liquid slugging can cause serious issues such as increased pressure in the compressor, potential mechanical failures, and unsafe operating conditions. By shutting off the compressor, the operator can prevent further liquid from entering the compressor, allowing the system to stabilize and address the issue safely.

The effective response to liquid slugging typically involves isolating the compressor from the liquid carryover, which ensures that the machinery is not subjected to conditions outside its design specifications. It provides an opportunity for the operator to take corrective action, such as draining the liquid, before restarting the system, helping to ensure operational safety and equipment integrity.
