Title (EN) SYSTEMS AND METHODS FOR SEPARATING (E)-1-CHLORO-3,3,3-TRIFLUOROPROPENE, HF, AND A HEAVY ORGANIC AND REACTOR PURGE
(FR) SYSTÈMES ET PROCÉDÉS POUR SÉPARER LE (E)-1-CHLORO-3,3,3-TRIFLUOROPROPÈNE, HF, ET UNE MATIÈRE ORGANIQUE LOURDE ET PURGE DE RÉACTEUR
Abstract:
(EN) The present disclosure provides separation processes for removing heavy organics that are formed in various production processes of HCFO-1233zd(E). Such separation processes allow for the recovery and/or separation of the heavy organics from reactants that are used to form HCFO-1233zd(E), including HF. Such separation or recovery processes may utilize various separation techniques (e.g., decanting, liquid-liquid separation, distillation, and flash distillation) and may also utilize the unique properties of azeotropic or azeotrope-like compositions. Recovery of the heavy organic that is substantially free from HF may allow for their use in subsequent manufacture processes or disposal.
(FR) La présente divulgation concerne des procédés de séparation destinés à éliminer les matières organiques lourdes qui se forment dans divers procédés de production de HCFO-1233zd(E). Ces procédés de séparation permettent de récupérer et/ou de séparer les matières organiques lourdes des réactifs qui sont utilisés pour former le HCFO-1233zd(E), dont le HF. Les procédés de séparation ou de récupération peuvent utiliser diverses techniques de séparation (p. ex., décantation, séparation liquide-liquide, distillation et distillation éclair) et peuvent également utiliser les propriétés uniques des compositions azéotropes ou de type azéotrope. La récupération de la matière organique lourde qui est sensiblement exempte de HF permet son utilisation dans des procédés de production ultérieurs ou de mise au rebut.
