<p>The vessel is for gases liquefied roughly at atmospheric pressure, and designed to be kept cold when the contents are removed. To do this, a false bottom (5) is provided near the top of the vessel (1), in which a layer of liquefied gas can remain behind. There can be a number of stiffening ribs (3) above the false bottom, forming a series of compartments. Some of these have closed floors, and means for regulating the liquid level above them, typically in the form of an overflow pipe (7).</p> |
