我们描述了一种新的，高能量（420千伏），大规模（0.45米的直径，4米的高度）的X射线断层扫描仪开发调查气体和液体流动通过固定床吸收，蒸馏和反应蒸馏塔。第一个结果获得了与此设置的测试对象（物理幻影），如一个圆柱形容器充满水或大直径结构化金属填料，验证了技术作为定量工具的几何测量。非常详细的二维（2D）和三维（3D）图像的0.09米直径KATAPAK-SP 12，反应蒸馏填料，提出。相对于液体滞留分布的定量信息可以从在填充有该元件的灌注柱上执行的层析成像获得。
We describe a new, high-energy (420 kV), large-scale (0.45 m in diameter, 4 m in height) x-ray tomograph developed to investigate gas and liquid flow through fixed bed like absorption, distillation and reactive distillation columns. The first results obtained with this set-up on test objects (physical phantoms), such as a cylindrical container filled with water or a large diameter structured metallic packing, validate the technique as a quantitative tool for geometrical measurements. Very detailed two-dimensional (2D) and three-dimensional (3D) images of a 0.09 m diameter KATAPAK-SP 12, a reactive distillation packing, are presented. Quantitative information relative to liquid hold-up distribution may be obtained from tomographic imaging performed on an irrigated column packed with this element.
