摘要/Abstract

摘要： A nonequilibrium stage model was used to simulate countercurrent multicomponent catalytic
distillation processes for methyl acetate hydrolysis. Computations of stage eiliciencies
or height equivalent to a theoretical plate (HETP) were entirely avoided by this model. The
consistency of simulated results and experimental data in conversions and concentration of
each component along a column indicates that the model predicts the actual process well.
The influences of operating parameters on hydrolytic conversions, such as feed molar
ratios, feed locations, feed and reflux rates, heights of reactive and stripping sections,
were analyzed adequately by simulating calcuiations. A good operating mode was then
obtained, which is helpful to the development of a new process.
