Abstract

Sous certaines variantes, l'invention concerne des appareils, systèmes et/ou procédés pour le fractionnement d'un mélange de charge qui comprend par exemple un ou plusieurs isocyanates, des composants légers, des solvants et/ou des composants plus lourds. Selon certaines variantes, ledit fractionnement peut consister à distiller le mélange cité dans un appareil de fractionnement non adiabatique qui comprend un étage et/ou une colonne de préfractionnement et une section et/ou une colonne principale, avec un étage de rectification, un étage latéral et un étage d'extraction. Par exemple, les isocyanates peuvent être séparés du ou des composants légers, du ou des solvants et/ou du ou des composants plus lourds. Un appareil de fractionnement peut être conçu et disposé, sous certaines variantes, comme une colonne à paroi de division. Selon certaines variantes, les appareils, systèmes et/ou procédés peuvent être efficaces en termes d'énergie et/ou offrir une large gamme d'exploitation.
