文中描述了内径为２５ｍｍ的超临界流体喷淋萃取塔内流体力学特性和质量传递性能。实验研究了二相流速、实验压力及不同物系对流体力学和质量传递的影响，并对超临界流体筛板塔、填料塔及喷淋塔的流体力学特性和质量传递性能进行了比较。
The paper describes the hydrodynamics and mass transfer properties of a 25 mm ID supercritical fluid jet extraction column. The effects of two-phase flow rate, experimental pressure and different systems on fluid mechanics and mass transfer were experimentally studied. The fluid mechanics and mass transfer performance of supercritical fluid sieve tray, packed column and spray tower were compared.
