【摘要】 在MATLAB下的SIMULINK环境中对醋酸生产进行了动态仿真。首先分析了乙醛氧化制醋酸的实际生产过程 ,建立了乙醛贮罐及阀门的数学模型 ,并把建立的数学模型转变为相应的SIMULINK方框图 ,同时还完成了氮气、氧气缓冲罐的模拟框图 ,并用模糊逻辑实现了乙醛贮罐的切换控制。更多还原

【Abstract】 Dynamic simulation of acetic acid oxidation tower was implemented in SIMULINK of MATLAB in this paper.First actual process of producing acetic acid by oxidizing acetaldehyde was analyzed,and secondly,mathematical model of acetaldehyde tank and valve were presented and the mathematical model was converted into corresponding SIMULINK block diagram.Simulation diagrams of nitrogen and oxygen buffer tank were found at the same time.Switch control of acetaldehyde tank was achieved with fuzzy logic.Dynamic simulation was implemented on computer and showed that the method was convenient and accurate.New idea was presented for chemical engineering process simulation.更多还原
