    摘要: The invention relates to a process for extracting water mixed with a liquid fluid. The process is characterized in particular by carrying out the following steps:forming a dispersion of hydrates of a gas within the fluid, these hydrates being formed from water and gas in a sufficient quantity, the gas being suitable for forming hydrates;separating the hydrates from at least most of the fluid, the hydrates possibly being with a remaining part of the fluid, andbreaking down the hydrates previously concentrated in order to obtain gas and water.
