Abstract
PURPOSE: To provide an economical method for sealing storage tanks by burning combustible gas extracted from the storage tanks and thereafter circulating the burnt gas as inert used for sealing the tanks.
CONSTITUTION: Storage tanks 1a,1b into which inert gas is introduced from a buffer tank 3 through the inert gas conduits 2a,2b are provided with gas extracting conduits 4a,4b connected to exhaust gas treating equipment 6. The equipment 6 comprises a preheating chamber 8 having a combustible gas preheater 10 and a combustion chamber 9 having a catalyst layer 11. Exhaust gas from the equipment 6 is heat recovered from an exhaust gas conduit 13 through the preheater 10 to be introduced into a buffer tank 3 by a flue 14.
