What is meant by seal gas?

• A. Gas used to fuel the motor
• B. Contaminated gas escaping from the system
• C. Dry, filtered gas supplied to a self-acting gas seal
• D. Gas escaping from the seal chamber

Answer: (C)

Seal gas refers to the dry, filtered gas that is supplied to a self-acting gas seal. The primary function of seal gas is to prevent the leakage of process fluids from equipment, such as compressors and pumps, to the atmosphere, thereby maintaining system integrity and safety. This gas acts as a barrier, creating a pressure differential that keeps contaminants from entering the system while also preventing the escape of potentially harmful substances. A self-acting gas seal relies on clean, dry gas to effectively form a seal. If the gas were contaminated or not properly filtered, it could compromise the seal's functionality, leading to leaks and operational problems. The quality of the seal gas is crucial for the effective performance of the sealing mechanism, highlighting the importance of utilizing filtered and dry gas in this application. By ensuring that the gas is free of impurities, the operational reliability of the rotating equipment can be significantly enhanced.
