Patent

CA 2261190

Process for removing water from compositions containing water, organics and hydrogen fluoride (e.g. product stream from vapour phase hydrofluorination processes, e.g. manufacture of HFA 134a, HFA 125 or HFA 32) by phase separation and purge of the aqueous layer.

L'invention concerne un procédé pour extraire de l'eau à partir des compositions contenant de l'eau, des matières organiques et du fluorure d'hydrogène (par exemple, flux de produit provenant des processus d'hydrofluorination en phase vapeur, fabrication de HFA 134a HFA 125 ou HFA 32) par séparation de phases et purge de la couche aqueuse.
