During an inert gas purge, the vessel is pressurized with the inert gas and then the pressure is relieved.

• A. True
• B. False
• C. Not sure
• D. Not applicable

Answer: (A)

Inert gas purge works by pushing out the existing air or vapors with a flow of an inert gas. When you pressurize the vessel with the inert gas, you create a driving force that displaces the air inside toward the vent. Releasing that pressure then allows the inert gas to exit through the purge line, maintaining a continuous flow that carries contaminants out of the vessel. This pressurize-and-relieve cycle is a standard purge method because it generates the necessary flow to sweep out air and residual vapors, helping to achieve an inert environment inside the vessel. If pressure weren’t relieved, the purge would lose its driving force and could become stagnant, making it harder to remove contaminants.
