Abstract:
The invention concerns a process for oxidative dehydrogenation of ethane. In the process an ethane comprising stream is fed to a distillation column to remove propane. The purified ethane stream is subjected to oxidative dehydrogenation using a catalyst comprising Mo/V/Sb, or Mo/V/Nb and Te or Sb in the orthorhombic M1 crystalline phase. The reactor effluent comprises ethylene. The effluent is washed with water to remove acetic acid. The acetic acid is recovered from the aqueous stream by means of solvent extraction.

Claim (Index 12):
The process according to  claim 1 , wherein in step (e) the acetic acid is recovered from the liquid stream obtained in step (d) by means of solvent extraction to obtain an aqueous stream and a stream comprising solvent and acetic acid, followed by distillation of the stream comprising solvent and acetic acid to obtain a stream comprising acetic acid and a stream comprising solvent.
