| 摘 要： | 引 言2 0世纪 80年代末 ,余国琮、杨志才等[1] 参照连续精馏开工过程的操作方法提出并实验证明了一种新的间歇精馏操作方法———塔顶累积全回流法(本文简称“全回流”) .采用此法 ,笔者[2 ] 最近推导出在理想操作条件下间歇精馏二元理想混合物精馏过程中塔顶贮槽内液体流动为完全混合时最小汽化总量计算法 .由于采用此法 ,塔顶贮槽内存液量可能很大 ,往往必须考虑塔顶贮槽内液体流动时的混合程度 .本文以多级串联混合模型的级数表示采用此操作方法塔顶贮槽内液体流动时的混合程度 ,以在理想操作条件下间歇精馏二元理想混合物为例 ,通过举…

| Abstract: | It is presented that the mixing level of flowing liquid in top vessel with batch distillation under total reflux and top accumulation i s represented by means of the stags of multistage mixing flow in series model, and its basic equations and numeric algorithm of batch distillation of binary ideal mixture under ideal operation condition are given. The effects of the m ixing level of flowing liquid in top vessel with batch distillation under the o peration method on the energy consumption is discussed by the calculated results of examples. |
