Abstract

The heights of transfer units, the heights of equivalent theoretical trays, and the pressure drops have been measured experimentally for structured packings 1, 2, and 3 with different geometrical parameters, all other things being equal. The experiments were carried out on a distillation column, a mixture of R114/R21 freons used as the working fluid. In terms of physical properties, freons are very close to cryogenic liquids (except for the density), which can significantly simplify the research task and enable getting necessary information. The mentioned packings differ significantly in their geometrical characteristics and, therefore, each of them can be optimal for mixtures with different physical properties. The objective of the research was to get the heat and mass transfer characteristics and pressure drops for different types of packings.

不同几何参数规整填料精馏塔传热传质特性分析

摘要

对于具有不同几何参数的规整填料 1、2 和 3，在所有其他条件相同的情况下，已通过实验测量了传输单元的高度、等效理论塔板的高度和压降。实验在蒸馏柱上进行，R114/R21 氟利昂的混合物用作工作流体。就物理性质而言，氟利昂非常接近低温液体（密度除外），这可以显着简化研究任务并获得必要的信息。上述填料的几何特性差异很大，因此，它们中的每一种都可以是具有不同物理特性的混合物的最佳选择。研究的目的是获得不同类型填料的传热传质特性和压降。
