催化蒸馏元件的流体力学性能

摘要

采用内径为206 mm的有机玻璃塔,在常温常压条件下,以空气和水为介质,对一种新型的反应液渗流式催化蒸馏元件进体力学实验研究,并研究了气相流通截面分率和固体催化剂在元件内装填高度对流体力学参数的影响;利用最小二乘法回归实验数据得到了床层压降、动持液量及泛点气速的预测关联式,各关联式误差均在±4.5%以内,可作为工业设计的参考依据。

Abstract：

Hydrodynamic performance of reaction liquid seepage catalyst packing were measured in a catalytic distillation column with air-water system in an organic glass column with a diameter of 206 mm at ambient pressure and temperature. The effect of various ratio of gas phase flow area and loading height of catalyst of the novel packing on the hydrodynamic performance were investigated. Correlations for the pressure drop and liquid holdup in the catalyst bed and flooding point were obtained by the least square method. And the average errors are under ±4.5%, which could be reference to the design of engineering.
