htu

The correlations of the packing factor of pressure drop, packing factor of flooding point, and HTU of the true liquid phase mass transfer were obtained.

获得了压强降填料因子、泛点填料因子，以及液相真实传质单元高度的关联式。

Inorganic Ca/ silicone SCA, BG-1, for high temperature use ( HTU), 1992& 1995,79 well-times, Eff 79.7%;

无机钙/有机硅高温固砂剂BG-1（1992~1995,79井次，79.7%）；

Meanwhile, a correlation of HTU of mesh plate column with the factors such as rotating speed, flow rate, viscosity and holding-up rate is obtained.

并获得网格塔传质单元高度与转速、流率、粘度及滞存率等各因素的关联式。

The minimum liquid& vapor ratio and the Height of Mass Transfer Unit "HTU" can be obtained in lack of interphase heat transfer coefficient by the model.

利用该模型可以在缺乏相间传热系数的情况下，计算出最小液-汽比及传质单元高度HTU。

Under the same dispersed phase flow rate, the HTU is only 1/ 2~ 1/ 3 and the extraction efficiency is 2~ 3 times higher in spray extraction than that in liquid-liquid extraction.

在相同分散相流量下，喷射萃取的传质单元高度比液液萃取低1/2～1/3。
