Abstract
A method is disclosed of coupling and integrating natural gas recovery and separation along with chemical conversion. The method can comprise extracting at least one natural gas component. Non-limiting examples of the extracted component include ethane, propane, butanes, and pentanes. The method can also comprise contacting a natural gas stream with a catalyst under conditions that selectively convert at least one component into at least one product, such as ethylene, acetic acid, polyethylene, vinyl acetate, ethylene vinyl acetate, ethylene oxide, ethylene glycol, and their derivatives, propylene, polypropylene, propylene oxide, propylene glycol, acrylates, acrolein, acrylic acid, butenes, butadiene, methacrolein, methacrylic acid, methacrylates, and their derivatives, which can then be separated from the remaining components. The method can further comprise integrating production of ethylene, acetic acid, and/or vinyl acetate with polymerization of ethylene-based polymers, such as polyethylene, ethylene vinyl acetate, ethylene vinyl alcohol, polyvinyl acetate, or polyvinyl alcohol.
