Vaporization method device

Process and apparatus for demineralizing water include a fibrous microporous body having interfiber spaces in communication with one another and a porosity at least equal to 50%, water supply elements for supplying water to be demineralized through the fibrous microporous body, a heating device adapted to heat the fibrous microporous body to a temperature of at least 60.degree. C., and elements adapted to collect the demineralized water.

A method and apparatus are disclosed for detecting the presence of steam in a volume of air at a predetermined temperature. The apparatus includes a temperature sensor having two respective temperature build-up times representing an under steam temperature build-up time and an under air temperature build-up time. The method for detecting the presence of steam comprises the steps of placing the temperature sensor in the presence of the volume air, such that the sensor can reach a predetermined set point temperature that is lower than the predetermined temperature, taking a temperature measurement with the sensor, and determining if the measured temperature reaches the set point temperature in order to indicate whether the sensor is in the presence of steam.

The present invention relates to a process for at least partial dehydration of an aqueous composition, in which said composition to be dehydrated is brought into contact, through the intermediacy of a microporous hydrophobic membrane, with a receiving phase whose water activity is substantially lower than that of the aqueous composition and in which the aqueous composition, at least partially dehydrated, is recovered. The invention also relates to devices enabling the process to be implemented, especially continuously.
