摘要:
A system and method of removing product from sludge at a bottom of a storage tank that includes introducing a liquid to the tank, heating and agitating the liquid to separate the product from the sludge, and then removing the separated product and removing the introduced liquid.
摘要:
Underwater gas pressurization units and liquefaction systems, as well as pressurization and liquefaction methods are provided. Gas is compressed hydraulically in vessels that are used to reach a high compression ratio that lowers the liquefaction temperature. The pressurizing liquid or seawater is delivered gravitationally, after gasification, transport to smaller water depths and condensation. Cooling units are used to liquefy the compressed gas. A cascade of compression and cooling units may be used with sequentially higher liquefaction temperatures, which allow eventual cooling by sea water. Additionally, methods, systems and units for liquefaction of combustible material are provided. Aqueous salt solution having separates combustible material from waste rock and after heating and grinding the separated combustible material yields a paste of purified combustible material, which is fluidizing and hydrogenated underground in a hydrogenation chamber.

Provided are gravitational separation systems and methods for sorting crushed material, underwater mineral dressing and Desalination and rinsing. Crushed material is gravitationally separated according to component densities in a liquid column having a bottom layer of a heavy water- immiscible liquid, an intermediate layer of an aqueous salt solution and a top layer of a light water- immiscible liquid. Material is milled in a water-immiscible liquid which is heavier than water and lighter than the product material. Desalination and rinsing use a liquid column to efficiently perform freeze desalination and enable recyclable washing of produced minerals or combustible material. The liquid column comprises alternating layers of water immiscible liquids and water solutions which form a vertical density gradient (discrete or continuous) and exhibit a lower freezing zone from which ice floats to an upper melting zone.
摘要:
A system and method for cleaning an above ground storage tank, where the side walls of the tank are separable from a bottom of the tank. Verticals members may be attached to the side walls of the tank, and a lifting force may be applied to the vertical members by a series of jacks so that the side walls are raised above the bottom. The side wall may be suspended above the bottom while the tank is cleaned out, and then lowered again when the cleaning is complete.
