PROCESS FOR PRODUCING ACETIC ACID |
摘要 |
Process for producing acetic acid is disclosed in which the reaction medium is separated into a liquid recycle and a vapor product stream including acetic acid, methyl iodide, methyl acetate and water in a flash vessel. The vapor product stream is condensed into a liquid stream that is enriched in acetic acid and this liquid stream is further sent to the distillation columns to recover acetic acid. The process advantageously improves the capacity of the acetic acid production while reducing the amount of acetic acid that is recycled. |
