Abstract
Disclosed is a method for controlling the decanter phase separation of an acetic acid production by methanol carbonylation. The method comprises measuring the methyl acetate concentration of the reactor mixture, calculating the density of the decanter heavy, organic phase according to the measured methyl acetate concentration, and adjusting the conditions in the reactor or in the decanter to ensure phase separation of the decanter.
