The
middle vessel batch distillation process for separating the
methyl formate/methanol/water ternary system was simulated using Aspen
Plus and Aspen Plus Dynamics. The composition control structure (CCS)
and temperature control structure (TCS) were studied in a dynamic
simulation based on the results of a steady-state simulation. Two
temperature control structures, one the traditional TCS and the other
TCS with high selectors, show better control performances than CCS.
The two control structures can stably control the product purities
and liquid holdups in the product vessels at the end of the batch.
The results show that TCS with high selectors is better than traditional
TCS in terms of the liquid holdups. The performance of the TCS with
high selectors is assessed, and controllability is demonstrated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
