Claim 1:
2. A chemical complex for oxidative dehydrogenation of ethane and production of vinyl acetate monomer, the chemical complex comprising in cooperative arrangement:
i) at least one oxidative dehydrogenation reactor, comprising an oxidative dehydrogenation catalyst and designed to accept, in the presence of an inert diluent, an oxygen containing gas and an ethane containing gas, and to produce a product stream comprising ethylene, acetic acid, oxygen and carbon monoxide;
ii) a quench tower for quenching the product stream and for generating an acetic acid stream comprising acetic acid and an ethylene product stream comprising ethylene, carbon monoxide and oxygen;
iii) a distillation tower for separating at least a portion of the ethylene product stream into a C2/C2+ stream and an overhead stream;
iv) an oxygen separation module to separate oxygen from the overhead stream and form an oxygen enriched gas;
v) a carbon monoxide oxidation reactor for oxidizing carbon monoxide to carbon dioxide and eliminating acetylene in the ethylene product stream; and
v) a vinyl acetate monomer (VAM) reactor configured to accept a portion of the ethylene product stream and at least a portion of the acetic acid stream and including a VAM catalyst to produce a VAM product stream comprising vinyl acetate monomer.
