<p>A system for producing 1,1,1,2,-tetrafluoropropene comprising :
a) hydrogenation reactor (R21),
b) a starting material feed stream (F2), comprising hexafluoropropene, connected to said hydrogenation reactor,
c) a reaction mixture of hydrogenation (S21) connected to a first distillation column (T21),
d) a low-boiling fraction S22 of distillation is connected to a deshydrofluorination reactor (R22),
e) optionally a recycle stream comprising of 1,1,1,2,3,3,-hexafluoropropane, high-boiling point component of distilladon column is connected to the hydrogenation reactor,
f) a final product stream of 1,1,1,2-tetrafluoropropene connected to the dehydrofluorination reactor.</p> |
