摘　　要：研究了五区模拟移动床(SMB)工艺分离三元组分的性能,采用1-1-1-1-1、2-2-2-2-2、3-3-3-3-3共3种色谱柱配置分析区域中的色谱柱数量对分离产品纯度的影响,同时,为了提高五区五柱SMB的分离性能,采用了以下两种优化方法,第1种方法是采用一种改进的SMB技术,即进料浓度可变的Modicon工艺;第2种方法是利用粒子群算法对SMB分离过程的操作参数进行优化。结果表明,以上两种优化方法都可以提高分离产品的纯度和生产率。Making use of five-zone simulated moving bed(SMB)process to separate the performance of ternary components was implemented,including adopting three column configurations(1-1-1-1-1,2-2-2-2-2,3-3-3-3-3)to analyze effect of the number of columns in the zone on the purity of the separated prod-ucts.In addition,for purpose of improving the five-zone and five-column SMB's separation performance,the following two optimization methods were adopted,of them,the SMB technology improved is a Modicon process with variable feed concentration,the latter employs particle swarm optimization to optimize operating parameters of SMB separation process.The results show that,the above two optimization methods can improve both purity and productivity of the separated products.
