| titleOfInvention | A process for removing water from a mixture |
| abstract | A process for removing water from a mixture (2) with a given compound provides bringing a carbon dioxide-containing gas stream (3) into contact with such mixture (2) in a treatment container (11), so that the carbon dioxide reacts with the water of the mixture (2) forming carbonic acid; maintaining a treatment temperature preferably higher than 40°C, and withdrawing an exhaust gas stream (4) from the container (11), until a final concentrate (2') is obtained having a predefined target mass ratio between said water and said compound. His way, the water is progressively withdrawn from the mixture (5) as long as the carbon dioxide-containing gas (3) is supplied, without requiring either a high-temperature heat source at or a high amount of heat. The mixture (2) can be, at least when the treatment starts, a homogeneous solution, for example a salt solution to be concentrated or from which the compound should precipitate or crystallize, which is the case, for instance, of a treatment for removing metal cations from an acid waste, or of a treatment of crystallizing or even drying a salt; as an alternative, the mixture can be a wet solid such as a sludge that should be concentrated and/or dried. Advantageously, steps are also provided of condensing the water contained in the exhaust gas (4) and of recovering and recycling the carbon dioxide, an incondensable gas, to the treatment container (10). |
