Abstract: A method and system for reducing a water content in a substance, comprising: mixing a water-and-solid-containing substance with a liquefied gas solvent creating a mixture and at least part of water in the water-and-solid-containing substance to be extracted into the liquefied gas solvent; separating the mixture into a substance with a decreased water content and a solvent with an increased water content, comprising the liquefied gas solvent and water extracted from the water-and-solid-containing substance; separating the solvent with an increased water content into a liquefied-gas-solvent-rich phase and a water-rich phase by changing a temperature of the solvent with an increased water content, and in a process of changing the temperature, keeping the temperature to be lower than a boiling point of the liquefied gas solvent under a pressure in the process; and returning at least part of the liquefied-gas-solvent-rich phase to be used as a solvent in creating the mixture.
