Enhancing the Separation Efficiency in Acetic Acid Manufacturing by Methanol Carbonylation

Acetic acid is an essential chemical used in the production of many products. Using methanol as bio-building block, acetic produced may be incorporated bio-based This study deals with enhancing efficiency separations a process using homogeneous catalyst, which most applied today industrially. Several configurations for downstream processing by distillation are investigated effective combinations fully thermally coupled columns, namely, dividing-wall alone or combined heat pumps. The results indicate that three-column direct sequence effectively replaced two-column sequence. Overall, total annual cost reduced 34 %. compressor paid back 1.5 years saved energy. Low energy intensity achieved tight integration reaction section.
