<p>An improved water seal drum for gas comprising a vessel containing seal water, a gas introducing pipe extending downward from the upper part of the vessel, the lower end of the pipe opening beneath the water level, and a gas discharging pipe at the top of the vessel; characterized in that the gas introducing pipe is equipped with gas dispersing pipes having multiple nozzles for releasing the gas at a location above the lower end of the gas introducing pipe but beneath the water level. The drum enables stable water seaing of gas in a wide range of gas flow rates, and is particularly useful as a water seal drum for inflammable waste gases to be burned in a flare stack.</p> |
