This work explains the production of isopropyl myristate (IPM), an ester formed from the esterification reaction of myristic acid and isopropyl alcohol in a reactive-distillation column. The design of the column has been done to achieve a dual process objective of achieving product purity of 99% and reactant conversion (99%) to produce 1000 kg/hr IPM at 30°C and about 1 bar pressure conditions existing within the column. The reboiler duty comes to be 190 kW against the condenser duty of 160 kW when an entrainer, cyclohexane at 1975 kg/hr is used, which can be reduced by employing two columns. The nonlinear quaternary system is solved using NRTL thermodynamic package, and the reactive distillation column is designed. The IMC-PID-based temperature controller has been designed for a closed-loop structure to achieve safe operation and desired dynamic control behavior and simulated by using MATLAB. The column has been stable under both steady-state and dynamic conditions by stabilizing the non-linear performance of the column by the controllers. The process integration of the reactor and separator into one column has minimized a process plant's operating and investment cost. |
