Desalting of sea water by a wall-less evaporation process; Dessalement de l'eau de mer par un procede d'evaporation sans paroi

Abstract

The need for fresh water supplies in many parts of the globe has given a great impetus to the study of the desalting of sea-water. Research into this problem has been very varied. Although it is possible in the more-or-less near future that methods based on freezing may be developed, only evaporation methods have industrial applications at the present time. Amongst the many techniques using this method, the most favorably placed installations from the technical and economic points of view are those based on multiple effects and wall-less heat transfer. We have defined the characteristics of a wall-less evaporation process using the various factors involved in this evaporation: energy source, corrosion, furring, heat transfer, maximum temperature, etc... The unit considered in this work has a daily output of 100,000 m{sup 3}, and makes use of the multi-stage technique with an organic heat-carrier. The maximum temperature of the first stage is 150 deg C and the evaporation factor is 0.4. After the description of the process and, the calculation of the equipment, an economic estimate is given of the cost-price : 1.49 F/m{sup 3}. It is likely that more detailed study of the process (technique, equipment and energy consumed) should make  More>>

(authors) [French] Le probleme de l 'approvisionnement en eau de nombreuses regions du globe a mis a 1'ordre du jour le dessalement de l'eau de mer. Des recherches sur cette question ont ete faites dans de multiples directions. Si dans un avenir plus ou moins proche les procedes par congelation peuvent se developper, actuellement seules les methodes d'evaporation ont des applications industrielles. Parmi les nombreuses techniques qui visent a mettre en oeuvre ce principe, les installations a multiples effets et transfert de chaleur sans paroi semblent les mieux placees du point de vue technique et economique. A partir des divers facteurs intervenant dans l'evaporation: source d'energie, corrosion, entartrage, transfert de chaleur, temperature maximale, etc... nous avons defini les caracteristiques d'un procede d'evaporation sans paroi. L'uni te calculee dans l'ouvrage a une capacite journaliere de 1000.000 m{sup 3}, utilisant la technique multietage avec un caloporteur organique. La temperature maximale au premier etage est 150 deg C et le facteur d'evaporation est de 0,4. La description du procede et le calcul des appareils sont suivis d'une estimation economique qui permet de prevoir un prix de revient de 1,49 F/ m{sup 3}. On peut penser qu'une etude plus approfondie de ce procede technique, appareils et energie fournie, permettrait d'ameliorer sensiblement 1'installation et de porter a 1 F le prix du metre cube.
