A comparison of control architectures for controlling a CSTR for acrylic acid production

Stochastic Multilayer Optimization for an Acrylic Acid Reactor

“…Finally, the authors concluded that the controllability performance of a CSTR for producing acrylic acid is excellent, in contrast to the use of a tubular reactor, which appears to be problematic . A comparison of the performance of three different control structures for controlling the acrylic acid reactor was achieved from a dynamic point of view . This work has shown the effectiveness of using an Economic Nonlinear model predictive controller (E-NMPC) for improving economic profitability and control performance of the process.…”

“…56 A comparison of the performance of three different control structures for controlling the acrylic acid reactor was achieved from a dynamic point of view. 57 This work has shown the effectiveness of using an Economic Nonlinear model predictive controller (E-NMPC) for improving economic profitability and control performance of the process. Despite the progress in acrylic acid process design and optimization of the reaction section in the steady state and dynamics, the consideration of process uncertainties is essential to obtain a more realistic solution to the problem.…”

“…Due to the importance of acrylic acid (AA) in the chemical industry, some works have improved the steady-state and dynamic process operation. − However, in addition to the steady-state and deterministic dynamic optimization, it is important to consider the possible sources of uncertainties that affect the acrylic acid process to obtain a more robust solution. In this work, stochastic dynamic optimization of the AA process is addressed for achieving maximum profitability while fulfilling safety constraints keeping good behavior of the control system for tracking the optimal state trajectories.…”
