An improved apparatus and method of producing acetic acid includes condensing overhead vapor to provide reflux to the light ends column as well as condensing vapor from a central portion of the light ends column to increase capacity. Throughput or load on the light ends column is substantially reduced without compromising product quality.
La présente invention concerne des appareil et procédé améliorés de production d'acide acétique comprenant la condensation de la vapeur de tête afin de porter à reflux une colonne contenant des fractions légères tout en condensant la vapeur issue d'une partie centrale de la colonne contenant des fractions légères afin d'accroître sa productivité. Le débit de la colonne contenant des fractions légères ou les sollicitations exercées sur celle-ci sont fortement réduits sans que cela nuise à la qualité du produit.
