摘要

INTEGRATED PROCESS FOR THE PRODUCTION OF ACETIC ACID AND VINYL ACETATE AND INTEGRATED SYSTEM FOR PRODUCING ACETIC ACID AND VINYL ACETATE Integrated processes and systems for producing acetic acid and vinyl acetate are provided. In processes and systems, a portion of the heat produced during the production of acetic acid is transferred to the production and / or vinyl acetate system and purification process to facilitate production and / or purification of the vinyl acetate product. The process and systems described herein are useful in conjunction with any of several known processes for the production of acetic acid and vinyl acetate. The heat of the acetic acid production reaction may be transferred to the vinyl acetate production system by any suitable heat transfer processes and systems. Heat may be provided to the purification section at a variety of locations in vinyl acetate production and purification systems, depending on the specific system configuration for which the processes and systems are concerned. The process and systems described herein are useful for providing cost and energy savings in vinyl acetate production processes.
