Computerized systems and methods for temperature profile control in a reactor with a series of fixed beds

A method comprising:

• identifying, by a processor, a set of values of a first fixed bed of a reactor with a series of fixed beds;
• determining, by the processor, based on the identified values, a predicted temperature differential for the first fixed bed;
• determining, by the processor, an actual temperature differential for the first fixed bed;
• determining, by the processor, based on the predicted temperature differential and the actual temperature differential, a model error for the first fixed bed;
• applying, by the processor, a model predictive control (MPC) algorithm to the determined model error;
• and automatically controlling, by the processor, based on the application of the MPC, a temperature profile of the reactor, the temperature profile corresponding to each of the series of beds in the reactor, the temperature profile providing functionality for temperature control of reactions in each of the series of beds to compensate for feed composition changes.

A non-transitory computer-readable storage medium tangibly encoded with computer-executable instructions, that when executed by a processor associated with a computing device, performs a method comprising:

• identifying, by the processor, a set of values of a first fixed bed of a reactor with a series of fixed beds;
• determining, by the processor, based on the identified values, a predicted temperature differential for the first fixed bed;
• determining, by the processor, an actual temperature differential for the first fixed bed;
• determining, by the processor, based on the predicted temperature differential and the actual temperature differential, a model error for the first fixed bed;
• applying, by the processor, a model predictive control (MPC) algorithm to the determined model error;
• and
• automatically controlling, by the processor, based on the application of the MPC, a temperature profile of the reactor, the temperature profile corresponding to each of the series of beds in the reactor, the temperature profile providing functionality for temperature control of reactions in each of the series of beds to compensate for feed composition changes.
