Optimized plant operating region and alarm limit advisory

A method for operating at least one asset of an industrial plant in an optimized operating region, the method comprising:

• selecting a range of values for one or more process variable input parameters associated with the at least one asset;
• simulating operation of the industrial plant based on the process variable input parameters to produce a range of values of simulated output parameters of the industrial plant;
• identifying at least one boundary condition between a first operating state and a second operating state as represented by the simulated output parameters;
• identifying a sub-range of the selected range of values for the one or more process variable input parameters for which the simulated output parameters are within an optimum range of values based on the at least one boundary condition;
• and
• setting one or more alarm limits configured to maintain operation of the at least one asset such that the industrial plant produces output parameters within the optimum range of values based on the one or more process variable input parameters in the identified sub-range.

A system comprising:

• at least one industrial asset;
• at least one controller communicatively coupled to the asset;
• a processor;
• and
• one or more memory devices coupled to the processor, the memory devices storing processor-executable instructions that, when executed, configure the processor to:
• select a range of values for one or more process variable input parameters associated with the at least one industrial asset;
• simulate operation of the industrial plant based on the process variable input parameters to produce a range of values of simulated output parameters of the industrial plant;
• plot the process variable input parameters and the simulated output parameters on at least one parallel coordinates plot;
• identify, from the parallel coordinates plot, at least one boundary condition for efficient operation between a first operating state and a second operating state as represented by the simulated output parameters;
• identify a sub-range of the selected range of values for the one or more process variable input parameters for which the simulated output parameters are within an optimum range of values based on the at least one boundary condition;
• and
• set one or more alarm limits for the at least one industrial asset via the controller, the alarm limits configured to maintain operation of the at least one industrial asset such that the industrial plant produces output parameters within the optimum range of values based on the one or more process variable input parameters in the identified sub-range.
