摘要：为了研究精馏分离高品质芳樟醇的工艺条件,考察芳樟醇产品纯度与能耗的关系,应用Aspen Plus软件分析了芳樟醇与芳樟型樟树叶精油其他主要成分的二元系统在1 k Pa下相平衡的关系,并建立单塔精馏和双塔精馏分离模型,对芳樟型樟树叶精油分离芳樟醇的工艺进行了模拟,结果分别得到了含天然芳樟醇95.4%和99%的产品,双塔精馏的塔底热负荷之和为单塔精馏的2.6倍。模拟结果表明,芳樟醇产品中的樟脑含量是影响精馏工艺参数的关键因素。
In order to study process conditions of separating high-quality linalool, and investigate the relationship between purity of linalool and energy consumption, the equilibrium relationship of linalool and the other main components in Cinnamomum camphora leaf essential at the pressures of 1 kPa was analyzed by Aspen Plus software, separating models of single-tower and double-tower were established, and separating process of linalool from C. camphora leaf essential oil was simulated. The productions with 95.4%and 99%of linalool were obtained, and heat duty of double-tower distillation was 2.6 times as much as that of single-tower distillation. The results showed that camphor content in linalool products was the key factor affecting the distillation process parameters.
