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 content. 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.

A storage tank isolation system for a storage tank includes a vertical riser attached to a top of the storage tank and having a cover with an aperture and a connecting member extending from a side of the vertical riser. A distal end of the connecting member is parallel to the top of the storage tank and attached to a storage hatch. The storage tank isolation system includes a valve assembly, which includes a stem extending through the aperture in the cover, a valve plate attached to the stem, and a valve seat sealed to the vertical riser at a position below a connection to the connecting member. The valve plate is moves with the stem from an open position in which the valve plate is held within the vertical riser at a position equal to or above the connection to the connecting member and a closed position.

Methods, systems, and apparatus for the safe storage of atmospheric air inside a vessel that stores volatile liquid and vapors. The apparatus includes a storage tank defining a tank cavity for storing the volatile liquid and vapors. The apparatus includes a tube having a top opening positioned outside the tank cavity and a bottom opening positioned within the tank cavity. The apparatus includes a bag flange connected to the tube bottom opening and located within the tank cavity. The apparatus includes a bag connected to the bag flange and located within the tank cavity, the bag receiving or emitting atmospheric air via the tube when the volatile liquid and vapors stored within the storage tank contract or expand due to variations in temperature of the stored volatile liquid and vapors, and a weight and a location of the bag within the tank cavity being supported by the bag flange.
