  • METHODS AND SYSTEMS OF MONITORING FLAMMABILITY OF VARIOUS STREAMS DURING VINYL ACETATE PRODUCTION
    Publication number: 20230312453
    Abstract: Methods and systems for producing vinyl acetate may use flammability limit (FL) formulas with improved efficiencies at more than one location in the vinyl acetate production process. Herein, FLs can be used at one or more of four portions of the vinyl acetate production process: the reactor, the process-to-process heat exchangers, the carbon dioxide removal system, and the ethylene recovery system. Such FLs are functions of operating conditions and include at least one interaction term that represents the interrelation of two or more of the operating conditions (e.g., temperature, pressure, and component concentration) on the FL.

  • Recovery of Acetic Acid from Heavy Ends in Vinyl Acetate Synthesis Process
    Publication number: 20120149939
    Abstract: Recovery of acid, and in particular acetic acid, in a vinyl acetate production process. Vinyl acetate production produces heavy ends that comprise acetate containing compounds, such as monomers and polymers. Acid preferably is recovered by hydrolyzing the heavy ends and separating the resulting hydrolyzed stream to recover acid formed from the from acetate containing compounds.
