Stable real-time optimization simulation system for catalytic cracking absorption

The invention relates to a catalytic cracking absorption stability real-time optimization simulation system. The system is composed of a real-time optimization simulation interface, a real-time optimization simulation calculation file and a real-time data acquisition module. The real-time optimization simulation interface is used for providing a man-machine interaction window, a user modifies unit processing cost and product price information on the real-time optimization simulation interface, and all real-time optimization results are fed back to the user through the real-time optimization simulation interface; the real-time optimization simulation calculation file is completed by one or more AspenPlus process simulation files with stable catalytic cracking absorption, and the real-time data acquisition module automatically identifies and calls the corresponding AspenPlus file to perform simulation calculation; the real-time data acquisition module acquires process data and test analysis data of a production
