Abstract

Colonne de distillation à cloches à bulles d'entretien facile, pour distillation de liquides encrassants et/ou à forts dépôts Colonne de distillation caractérisée en ce que les structures de cloches à bulles peuvent être démontées et retirées de la colonne, et en ce que les surfaces intérieures des cloches à bulles et les surfaces intérieures et extérieures des collets de cloches à bulles, surfaces les plus critiques pour l'encrassement de la colonne, sont recouvertes d'un revêtement de polytétrafluoroéthylène ou d'une substance analogue. L'invention s'applique aux cloches à bulles pour liquides encrassants et/ou à forts dépôts.
