Design of the <i>tert</i>-amyl methyl ether (TAME) production
process has received much attention because TAME is an important oxygenated
gasoline additive with much fewer environmental and health issues
than methyl <i>tert</i>-butyl ether. Although a reactive
dividing wall column where reaction and separation take place in one
vessel has been developed with less capital and operating cost, little
work on its application to TAME production has been reported. In this
paper, we propose a new overall procedure for optimal design of the
TAME production process through an integrated reactive dividing wall
and pressure swing columns, which includes screening of the best dividing
wall configuration, thermodynamic feasible insight, and process simulation
and optimization using the sensitivity analysis tool in Aspen Plus.
The computational results demonstrate that the optimal design of the
TAME production process through an integrated reactive dividing wall
and pressure swing column is successfully obtained to achieve desired
TAME purity of 99.958 mol %, significantly reducing the total annualized
cost by 43.58% and decreasing the exergy loss by 48.24% compared to
the existing TAME production process using reactive distillation.
Finally, an effective control strategy including tray temperature
control is proposed to ensure the operating conditions are well controlled
at or close to their set points in a desired time when disturbances
occur.
