Abstract:
The invention relates to an integrated process for the production of ethylene and vinyl acetate (VAM), comprising contacting in a first reaction zone a gas stream comprising ethane and optionally ethylene with an oxygen-containing gas stream in the presence of a oxydehydrogenation catalyst under oxidative dehydrogenation conditions to produce a first product stream comprising ethane, ethylene, acetic acid and water, and optionally other compounds, separating said first product stream in a vapor permeation unit into a second stream comprising water and a third stream comprising ethane, ethylene, acetic acid, and optionally other gaseous compounds, contacting in a second reaction zone all or at least a portion of said third stream with a stream comprising concentrated acetic acid and with an oxygen-containing gas stream in the presence of a VAM catalyst, to produce a fourth product stream comprising vinyl acetate, acetic acid, ethane, ethylene, water, carbon dioxide, and optionally other compounds, separating said fourth product stream in a vinyl acetate separation zone into a fifth stream comprising vinylacetate, acetic acid, water and optionally other condensable compounds, and a sixth stream comprising ethylene, ethane, carbon dioxide and optionally other gaseous compounds, and recovering vinyl acetate from said fifth stream. The invention further relates to a reaction system for carrying out the process.
