Abstract (en)

[origin: WO2015008274A1] 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.
