Summary:The present invention relates, in part, an improved process for the production of certain hydrofluoroolefins, particularly 2,3,3,3-tetrafluoropropene (1234yf). In certain nonlimiting embodiments, the invention relates to methods for improving process efficiency during the fluorination of 1,1,2,3-tetrachloropropene, 2,3,3,3-tetrachloropropene, and/or 1,1,1,2,3-pentachloropropane to 2-chloro-3,3,3-trifluoropropene by separating and recycling unreacted HF, unreacted starting materials, and/or certain pro - cess intermediates from the 2-chloro-3,3,3-trifluoropropene product stream.
