A METHOD FOR ENERGY BENCHMARKING AND DIAGNOSIS THROUGH OPTIMIZATION AND A SYSTEM THEREOF

摘要

Exemplary embodiments relate to a method for energy benchmarking a process plant having at least one component, and for diagnosing the process plant thereof. The method includes adapting a process model for the process plant determining energy consumption of the process plant based on design conditions or current operating conditions or both and performing optimization for estimating the energy benchmark. Further, the method also includes calculating indices for gap analysis and diagnosing the gap between the current energy consumption of the process plant and the estimated energy benchmark.
