Abstract

Method of using a storage tank containing two liquids of different densities arranged one above the other in the tank, with interposition of a substantially horizontal separating partition whose periphery is connected by a watertight flexible separation skirt to the tank wall, in the proximity of one of the extremities thereof, and that it can move vertically with a certain clearance in the tank, characterized in that, in order to facilitate vertical movements of said partition and the correlative deformations of said skirt, and to reduce the wear of the skirt, a limited amount of an auxiliary liquid is placed in that of the two liquids contained in the tank that is located in contact with the wall of said partition that is located opposite said end of the tank, said auxiliary liquid being substantially not miscible with the stored liquid in which it is located and having u At a density slightly different from the density of the other liquid, the auxiliary liquid remaining in contact with the skirt and keeping it deployed, combining the action of said auxiliary liquid with the action of means for balancing the flexible skirt, said balancing means constituting a ballast in the event that the flexible skirt is attached to the top of the tank and having a positive buoyancy in the event that the flexible skirt is attached to the bottom of the tank.
