  • Method for recovery of ethylene in a recirculating gas process for the production of vinyl acetate
    Patent number: 7803965
    Abstract: The efficiency of vinyl acetate production is increased by scrubbing of off gas followed by CO2 absorption. A portion of the off gas containing substantial quantities of ethylene is recycled to the process, whereas another portion is employed in another ethylene consuming reaction. Despite not removing non-reactive gases, selectivity and yield based on ethylene are both increased.
