Title (EN) PROCESS FOR PRODUCING ACETIC ACID
(FR) PROCÉDÉ DE PRODUCTION D'ACIDE ACÉTIQUE
Abstract: front page image
(EN) 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.
(FR) L'invention concerne un procédé de production d'acide acétique au cours duquel le milieu de réaction est séparé en un courant liquide de recyclage et en un courant de produit de vapeur comprenant l'acide acétique, l'iodure de méthyle, l'acétate de méthyle et de l'eau dans un vaporisateur. Le courant de produit de vapeur est condensé en un courant liquide qui est enrichi en acide acétique et ce courant liquide est ensuite envoyé dans les colonnes de distillation pour récupérer l'acide acétique. Le procédé permet d'améliorer de manière avantageuse la capacité de production d'acide acétique tout en réduisant la quantité d'acide acétique qui est recyclé.
