The present invention relates to a buffer store comprising a closed vessel housing for accommodating a storage fluid, in particular water, wherein the vessel housing has at least one inlet opening, for the filling of the vessel housing with the storage fluid, and at least one equalization opening, which fluidically connects the vessel housing to the surroundings and permits a fluidic equalization with the surroundings. According to the invention, a gas-tight cover is also provided in the interior of the vessel housing, which cover is capable of reliably protecting the storage fluid against mixing with other fluids, for example the ambient air.

Systems and methods are disclosed for vaporization suppression. Vaporization suppression may include, for example, evaporation control and/or odor control. A layer of foam glass aggregates may be placed on a body of water. Bodies of water may include natural and man-made aqueous bodies (such as, for example, ponds, lakes, lagoons, reservoirs, tanks, pools, runoff areas, etc.). Water may include clean water, natural water, rainwater, runoff, industrial output, manure slurries, leachates, treatment effuse, etc.). When placed, the foam glass aggregates in contact with the water may have a first moisture constant. At equilibrium, the foam glass aggregates in contact with the water may have a second moisture content. The second moisture content may be greater than the first moisture content. The foam glass aggregates in contact with the water may have a bulk density at the second moisture content that is sufficient to maintain buoyancy at the surface of the body of water.

Method and apparatus for raising a floating roof included in a storage tank whereby a first and a first opposite force are applied between a floor in the storage tank and an internal surface of the floating roof. An additional set of forces are also provided and are constrained according to the first and first opposite force, not only in magnitude, but in position. By constraining these forces to be applied orthogonally to the floating roof, horizontal shear forces can be resisted thus reducing the likelihood of failure of a cribbing unit. By increasing these forces, the roof is raised.

A method for measuring a liquid volume and/or corresponding fill rate of floating roof tanks includes selecting an Area Of Interest (AOI) to be monitored at the earth's surface, gathering geographical coordinates of tanks in the AOI, and downloading and pre-processing a time series of SAR reference images covering the AOI. The method includes projecting geographical coordinates of the tanks on the time series of the images to determine pixel coordinates of the tanks, and determining tank dimensions through processing of the images at the pixel coordinates. The method includes downloading and pre-processing at least one new SAR image over the AOI and registering it on top of the reference images, and, for each tank of the AOI, detecting in the new SAR image a bright spot corresponding to the roof of the tank and converting its pixel coordinates into liquid volume and/or fill rate information.

A system for monitoring a floating roof of a liquid storage tank and a method for use of the system are described. The system includes linear position measuring devices to determine the vertical location and orientation of the floating roof within the storage tank and one or more transmitters to relay such information to a monitoring, recording, or control device, or to a remote computer network location. Typically, three measuring devices are used, positioned at or near the top of the storage tank and generally equally spaced around the perimeter of the tank. The system and method are useful to monitor the position and inclination of a liquid storage tank floating roof, such as may be used in the petrochemical, chemical and other industries where such storage tanks are in use.
