Abstract
L'invention concerne un procédé permettant de vaporiser un fluide contenant des composés vaporisables sensibles à l'oxydation, dans un vaporisateur dans lequel, à des fins de vaporisation, le fluide est mis en contact avec une surface solide chauffée, le contact direct entre la phase vapeur obtenue et la surface solide chauffée étant évité dans une large mesure. L'invention concerne en outre un vaporisateur comprenant une surface solide (16) pouvant être chauffée, un dispositif (2, 3) servant à chauffer ladite surface solide, et un dispositif (10) servant à amener un fluide contenant des composés vaporisables jusqu'à la surface solide. Le dispositif d'amenée de fluide est conçu et disposé (12, 14, 18) dans le vaporisateur de façon que le contact direct entre la phase vapeur obtenue et la surface solide pouvant être chauffée est évité dans une large mesure.
