WebOct 1, 2024 · By reducing the boilup ratio, more liquid leaves the bottom of the column and subsequently more acetic acid is produced. As shown in Fig. 7 (d) for boilup ratios less than 3 the purity of acetic acid decreases dramatically. The reboiler and the condenser heat duties decrease by lowering the value of boilup ratio. This is the reason for the ...
