In pipeline operations, which tool is used to remove liquids or separate gas pockets?

Explanation:
Removing liquids and preventing liquid-backed gas pockets is accomplished with a swab. A swab is a device that travels through the line and wipes or absorbs liquids from the interior, pulling them ahead of the pushing mechanism or into a dump point. As it moves, the swab clears accumulated condensate or water from the pipe, reducing liquid holdup and helping to break up or displace gas pockets so the gas or product can flow more smoothly. The other tools have different primary roles: a pig is a general cleaning or inspection tool, a gauge measures diameter, and a calibrator adjusts or verifies the pipe’s cross-section. The swab is specifically designed to remove liquids and manage gas pockets inside the pipeline.
