Abstract: In this paper, we report on the use of X-ray tomography to visualize and quantify the liquid load point in modular catalytic distillation packing elements (Katapak-SP11 and Katapak-SP12). The liquid load point corresponds to the liquid superficial velocity above which the catalytic baskets are totally filled with liquid. For liquid superficial velocity values higher than the liquid load point, the excess of liquid flows in the distillation section (Mellapak corrugated sheets). From images obtained by x-ray tomography, we show that the liquid load point is not unique. Its value depends off course on the gas flowrate, but it also depends significantly on the vertical position in the packing element and on the position of the packing element in the column. Its values also varies depending on the position of basket in the packing element (external or internal).
