Plantwide Process Control Simulation

Abstract

Process simulation is a valuable tool for the design of process control strategies, particularly for distillation columns. Typically, control strategies use conventional single-input-single-output (SISO) PID controllers. Therefore, designing a control strategy normally includes determining which process variables should be measured and controlled and which control valve should be paired with each controlled variable. Control strategy design also includes identifying locations in the process where conventional single-input-single-output PID controllers may not work well.
