Experimental and numerical studies were conducted on the performance and capacity of structured packings for mixture separation with very low separation factor. Different formations and conditions of the innovative structured packing PACK-2100 with high surface area were studied to evaluate the main characteristics such as dry pressure drop. In addition, numerical simulation was performed to describe the details of the flow structure in these modified structured packings. Three-dimensional computational fluid dynamics modeling of PACK-2100 allowed for comparing the pressure drop in both laminar and turbulent flow regime. The obtained experimental and numerical data demonstrate the potential contribution of the packing to high-efficiency systems with low separation factor.

A new high‐capacity structured packing (PACK‐1300) was investigated for the separation of mixtures with low separation factor. The effect of the inclination angle was studied. In order to enhance the pressure drop and the separation efficiency of PACK‐1300, the surface area and porosity were increased. In addition, comprehensive parametric studies were performed to evaluate the dry/wet pressure drop and mass‐transfer efficiency under various operating conditions. Increasing the inclination angle enhances the capacity and decreases the efficiency of the packings. PACK‐1300W reduced the dry and wet pressure drop significantly more than PACK‐1300Z. Finally, the separation efficiency results show that the height equivalent to a theoretical plate decreased with decreasing inclination angle.

In this paper, experimental studies are conducted to introduce a new high capacity structured packing (PACK‐2100) for the separation of mixtures with low separation factor. To improve the performance of this packing, extensive consideration is given to the construction of a new wire gauze structure packing through various hydrodynamic and mass transfer analyses. The surface area and porosity of new structured packing (PACK‐2100) are increased to enhance the pressure drop and the separation efficiency. In addition, comprehensive parametric studies are performed to evaluate the dry/wet pressure drop and mass transfer efficiency in different operating conditions of the presented packing. Our findings show that this new structured packing reduces dry and wet pressure drops more than 25 % compared to the traditional packing that is used for difficult separations such as Dixon 1/8, with the same specific surface area. In addition, the achieved Height Equivalent Theoretical Plate (HETP) of PACK‐2100 is significantly lower (about 20 %) than other conventional packings. Thus, the PACK‐2100 is highly recommended for the separation of stable isotopes such as 18O and 13C in the distillation process.
