【摘要】 在以偏微分方程形式的单柱色谱分离模型基础上,结合模拟移动床的各区流量和质量守恒关系,建立了模拟移动床色谱分离过程的数学模型。基于线上求解法开发了模拟移动床模型数值求解的软件平台,仿真研究结果表明,与通常的真实移动床模型相比,所建模型明确考虑进出料口的周期性切换,因此可以反映模拟移动床的真实情况。更多还原

【Abstract】 Based on the single column partial differential equation model for the industry chromatographic separation,the mathematical model of the Simulated Moving Bed chromatographic separation process is established from the flow and mass conservation relations of the SMB process.Method of line is used for the numeric model computations.Computerized simulation results show that compared with the true moving bed model,the established model takes into consideration the periodic switch at the feed inlets and outlets,hence reflects the conditions in a true SMB process.更多还原
