    Abstract: A process and an apparatus for obtaining pure water from seawater, comprising: a) a raw water is provided that comprises at least one non-volatile component (salt), b) the raw water provided is passed as cooling medium into a heat exchanger, c) additional heat is supplied to the raw water that is heated in the heat exchanger, d) the raw water from step c) is fed to an evaporation zone, e) a carrier gas suitable for water vapour is provided (air), f) the carrier gas is brought into contact with the raw water in counter current flow in the evaporation zone which contains baffles, wherein the carrier gas takes up water vapour from the raw water, g) the raw water that is obtained in step f) that is enriched with the at least one non-volatile component is taken off from the evaporation zone, h) the water vapour- loaded carrier gas from the evaporation zone is fed to the heat exchanger and is cooled in counter current flow to the raw water, wherein the water vapour present in the carrier gas partially condenses out, i) the carrier gas depleted in water vapour is passed out of the heat exchanger, k) the condensed water vapour is taken off from the heat exchanger as pure water, wherein the evaporation zone is operated substantially adiabatically, and wherein the carrier gas is transported by means of natural convection through the evaporation zone and thereafter through the heat exchanger.

    Abstract: The invention relates to a device for storing heat, comprising a heat storage medium, which for storing heat takes up heat and for using the stored heat gives off heat, and a tank for receiving the heat storage medium, wherein the tank is closed by a gas-tight covering, and means for volume equalization are comprised, in order to equalize an increase in volume of the heat storage medium (3) as a result of an increase in temperature and a decrease in volume as a result of a decrease in temperature. The invention also relates to a method for storing heat, in which, for storing heat, heat is transferred to a heat storage medium or, for using heat, heat is removed from the heat storage medium and passed to the heat transfer medium, wherein the heat storage medium is held in a tank, which is closed by a gas-tight covering, wherein an expansion of the volume of the heat storage medium (3) is equalized by an increase in the volume of the tank (1), or by heat storage medium (3) flowing out of the tank (1) into a buffer tank (21; 63, 65), and a decrease in the volume of the heat storage medium (3) is equalized by a reduction in the volume of the tank (1) or by heat storage medium (3) flowing out of the buffer tank (21; 63, 65) into the tank (1).
