【Abstract】 In response to the complex operating conditions of the multi-stage thermal integrated carbon three carbon four mixed dehydrogenation system, this study attempts to optimize its dynamic control strategy, solve control problems such as dynamic matching of heat source and heat sink, multivariable coupling, and disturbance suppression, and ensure the safe and efficient operation of the energy-saving system. In specific practice, in-depth analysis of the coupling characteristics of multiple variables such as heat pump waste heat classification utilization and aromatic solvent recovery is conducted, and a hierarchical control architecture is proposed. The research conclusion shows that the optimization strategy reduces the disturbance response time by 40% and the coking risk by 60%, providing a new idea for the dynamic control upgrade of multi-stage thermal integrated systems.更多还原
