Abstract

Pumpable wastes are mixed in salt caverns with soluble or dissolved salts, which crystallize at the cavern temperature with bonding of water of crystallization; or with organic waste materials which solidify in the liquid phase of the cavern contents or increase the density of the cavern contents; or with solid waste materials, whereby the specific gravity of the liquid phase is increased in order to narrow the difference between the specific gravity of the salt mineral of the cavern wall and the specific gravity of the liquid phase of the cavern contents and the caverns are sealed.
