Abstract

PURPOSE:To prevent rollover with mixing of a liquefied gas with agitation by floating or settling an agitating body with feeding of a liquefied gas to or discharging thereof from an overhung agitating body immersed therein in a storage tank for LNG or the like. CONSTITUTION:A part of a steam gas generated from a steam gas section 10 of a low temperature liquefied gas 1 is fed to a ring piping 15 by way of a conduit 14 and sealed fully into an overhung agitating body 18 from nozzles 16... so that the gas sealed floats the agitating body. When the agitating body rises up to the liquid surface, the gas filled dissipates through a hole 21 and the buoyancy reduces causing the agitating body to settle down into the liquefied gas. The low temperature liquefied gas 2 is mixed with the agitation by means of the agitation body 18 and an agitation blade 22 by repeating this procedure. Thus, the light and heavy LNGs are mixed so thoroughly as to attain as even density thereby preventing rollover.
