Abstract


Process simulation of complex industrial process means a thorough analysis of the key , it is the best decision on the system of the premise. In the industrial process, there are many unstable process of change , and only through dynamic simulation in order to better grasp the nature of these processes , so the process of dynamic simulation study is significant . Equation Oriented Dynamic Modeling time variable into the model system , namely the nature within the system and change over time . Dynamic model of the process simulation, control theory, thermodynamic model of organic chemical unit and combine to form a differential-algebraic system (Differential Algebraic Equations, DAEs). This article will gPROMS dynamic simulation software as a modeling tool and simulation environment , by calling the massive DAE solver algorithm for multi- class processes dynamic simulation , and the results are compared with the steady-state simulation results and analysis, discussion of dynamic , steady-state relations . The research work mainly includes the following aspects : ● Research gPROMS platform for dynamic simulation of the key issues , mainly through examples of this environment on the thermodynamic properties of substances called method of calculation ; analysis to solve a variety of different forms of the model algorithm ; summarize the dynamic simulation of various influencing factors . ● ethylene separation process are two important depropanizer distillation unit and Debutanizer as the research object , the massive tower couplet system dynamic model built in the start-up and operating point conversion and other dynamic process simulation , and will eventually reach a stable dynamic simulation results with Aspen Plus steady-state simulation results to compare. ● proposed move, steady relationship different issues related to the four categories of description , as well as from the model in the form of solving methods departure , in-depth study dynamic , steady-state relationship . Mainly in several different types of processes as examples, respectively, according to these categories describe different ways to model the problem , the model and the simulation results for comparison and summary.
