| 摘 要： | 在Oldershow玻璃筛板塔中,用四种两组元物系分别在两种筛板开孔率下进行精馏试验,回归得到的点效率经验关联式为。 E_(OL)=0.00935Sc_L~(0.15)Dg~(0.222)Re_O~(0.365) 本文还提出利用涡流扩散模型进行放大的方法。

EMPIRICAL CORRELATION OF POINT EFFICIENCY OF SIEVE PLATE DISTILLATION |
| |
| Abstract: | In the glass Oldershow sieve plate column, rectification experiments was taken with four different binary mixtures under two percent-open area respectively. The experimental data was regressed and empirical correlation of point efficiency is obtained:A scale-up method is proposed through eddy diffusion model in this paper. |
