Abstract


With the shortage of resources and rising energy prices , the market competition is becoming increasingly fierce , the pursuit of the desire to maximize production efficiency has become even more strongly . At the same time , with the increasingly large scale of industrial process , increasing complexity , traditional offline optimization technology can not meet the requirements of the high efficiency of the production process , for real-time optimization technology research in the field of operation optimization is becoming the new focus . This article aims to research the technology of real-time optimization of industrial processes starting from the point of view of practical application , select the TE (Tennessee Eastman) process as the object of study . First, in-depth analysis of the TE process , predecessors TE model based on the process flow of the entire process , taking into account , according to the requirements of real-time optimization techniques , materials and energy balance mechanism model adjustment factor the processing method, given a mechanism model of the process of the TE . Then , the paper system in-depth study of the steady-state operation of the TE process optimization problem to solve nonlinear programming method , this method is able to quickly and effectively complete the calculation of such complex and changeable amount nonlinear optimization problem . TE process - based simulation platform to study the impact of model uncertainty on the steady-state operation optimization results , carried out a detailed simulation and analysis . Finally, given the the TE process real-time optimized programs , including steady-state analysis , data correction , model update and optimization calculation link . The papers based simulation experiments to study the the TE process of steady-state operating point offset the impact of real-time optimization process , thereby laying the basis for real-time optimization embodiments .
