Le procede de distillation a multiple-effet avec evaporateurs a tubes horizontaux (THA)

Abstract The author reviews the work carriedout during some years on the THA process: research on cycles and. combinations of cycles suited to seawater desalination, setting up of the the corresponding computer codes ; experimental and theoritical studies to determine the best heat transfer conditions in THA evaporators He emphasizes the advantages of the THA process : possibility of working at higher -temperature and hence increasing water production : possibility of use of special tube which improve the heat exchange efficiency and thus reduce heat exchange surfaces, possibility of coupling with vapor compression apparatus
