PROCESS AND APPARATUS FOR PURIFYING WATER AND RECOVERING SUBSTANCES DISSOLVED IN WATER ABSTRACT OF THE DISCLOSURE To purify water and recover substances dissolved in water, the water is finely divided and introduced into an inert entrain- ment gas current, whereby a specified partial pressure is set for the entrainment gas in the mixture of entrainment gas and water vapor which is formed by heating the mixture of entrainment gas and water vapor to superheat the water vapor produced. The solid particles are separated from the entrainment gas water vapor mixture. The purified mixture of entrainment gas and water vapor is cooled until the water vapor condenses, and the heat released is recycled in the process. To heat the mixture of entrainment gas and water vapor, the water to be purified is first partly evaporated by the addition of heat, and the brine formed in the partial evaporation is introduced into the entrainment gas current. The water vapor formed during the partial evaporation, after the separation of the brine, is at least partly compressed and by giving up its heat is used on one hand to heat the entrainment gas current after the introduction of the brine to regulate the super- heated mixture of entrainment gas and water vapor, and on the other hand for the partial evaporation of the water. The purified mixture of entrainment gas and water vapor, with a condensation of the water vapor it contains, is used to preheat the water to be purified. 46
