摘要
针对氧燃烧技术对氧气的特殊需求,利用ASPEN PLUS软件对一概念深冷空分系统进行了过程模拟,并对系统中的重要部件—蒸馏塔进行了设计优化。优化变量选取蒸馏塔中的3个重要参数:总级数、入流级数以及回流率。在得到空气分离过程所需的最小总级数、最小回流率的基础上利用一定的经验代数关系得到了总级数和入流级数的最优值,并依此得到了此时的最佳入流级数。基于优化工况的结果,对整个系统进行了分析。
Regarding to the special oxygen demand of the oxy-combustion technology,a conceptual cryogenic air separation system was simulated using ASPEN PLUS.And a design optimization was conducted to the distillation column.Three parameters were chosen to optimize the column： feed stage,total number of stages and reflux ratio.After the minimal total number of stages and minimal reflux ratio were obtained,the optimum total number of stages and reflux ratio can be found out by using some experiential algebraic equations.Based on these optimum results,the optimum feed stage can be fixed.Finally,an exergy analysis was performed to the air separation system based on the optimum case.
