摘要

本文对工业天然气液化装置的两相闪蒸分离器进行了数值模拟。采用键合图方法建立了仿真模型,并利用MATLAB和20-sim软件获得了flash的动态特性。由于工厂信息中没有提供分离器的输入条件,使用MATLAB确定输入条件,并使用20-sim模拟键合图模型。利用该装置的实际运行情况对仿真结果进行了验证。本文展示了这两个广泛使用的计算机程序如何帮助理解实际过程的行为。

Use of MATLAB and 20-sim to simulate a flash separator

This work presents the simulation of a two-phase flash separator, one of the processes of an industrial natural gas liquefaction plant. The model simulated was developed using the bond graph methodology, and MATLAB and 20-sim software were used to obtain the dynamic behavior of the flash. MATLAB was used to determine the input conditions of the separator as they were not provided by the plant information, and 20-sim was used to simulate the bond graph model. The simulation results were validated using real operating conditions of the plant. The paper shows how this two widely used computer programs can help in the understanding of the behavior of real process.
