“…where μ is the viscosity of the gas phase. According to Miller, [37] the effect of the relative plate thickness on the pressure drop can be presented by the following empirical formula: From Equations (12) and (13), it can be seen that the difference in the hole distribution method is mainly reflected in the differences of the exponent of l/ h and d 0 /h, and this is in accordance with the simulated results. The ranges of the test parameters are as follows: 510.3 ≤ Re s ≤ 11 046.6, 0.115 ≤ α ≤ 0.176, 0.107 ≤ t/d 0 ≤ 0.250, 1.212 ≤ l/h ≤ 1.333, and 0.571 ≤ d 0 /h ≤ 0.606.…”

Figure 21A shows a comparison of the predicted pressure drop with the experimental pressure drop for packing D, and the predicted values are calculated from Equations (8) and (13). It can be seen that the calculated values agree well with the experimental data.…”

“…Under these circumstances, computational fluid dynamics (CFD) shows its advantages, such as that it is economical, simple, accurate, and efficient. [12,13] CFD technology has been widely used in researching the hydrodynamic process of the fluid in complex column interiors. [9,12,[14][15][16][17][18][19] It can not only provide a realistic picture of the internal flow field and critical hydrodynamic parameters for the design and performance analysis of the column, [12,14,20] but it can also enable changes in the geometric parameters of the interiors to be made using the single variable method and simulates the conditions where experiments cannot be conducted.…”

Comparative study of dry pressure drop and flow behaviour of gas flow through sieve plate packing

Sieve plate packing is a newly developed packing that has been used in several industries due to its simple structure and operating flexibility, and no liquid flooding. In this work, first, systematic experiments were conducted to measure the pressure drop of gas flow through six sieve plate packings. The results indicated that the geometric characteristics of the packing have complicated effects on the pressure drops. Based on this, CFD simulations on the gas flow field were conducted using the realizable k‐ε model, and flow behaviours such as the pressure drop, pressure nephogram, and velocity distributions within different packings were obtained. The simulation results clearly showed interesting flow patterns, including the contraction and expansion of the gas stream through the sieve hole, the flow separation on the sharp edge of the hole, and the vortexes formed when gas impacts the downstream plate. By comparing the flow patterns and the pressure drop under different packings operating at different conditions, the effects of the geometric characteristics of the packing on the pressure drop could be clearly distinguished from the flow behaviours, so that the variations in pressure drop with various packing structures were clearly indicated. Finally, based on the experimental data and the simulated results, correlations for the prediction of the pressure drops were proposed. This work will provide a useful basis for understanding the flow behaviour of gas and liquid two‐phase flow in sieve plate packing.

The novel wire gauze structured packing, PACK‐860, was characterized by means of numerical methods. The main features of PACK‐860 such as height equivalent to a theoretical plate (HETP) and dry/wet pressure drop were evaluated. The flow structure in this packing was described by numerical simulation. To estimate the amount of HETP and dry/wet pressure drop, three‐dimensional computational fluid dynamics (3D CFD) modeling with the Eulerian‐Eulerian multiphase approach was applied. The average relative errors between the results obtained from CFD simulation and experimental findings for mass transfer efficiency and wet and dry pressure drop were assessed. Numerical observations were found to agree well with the empirical results, proving the reliability of CFD simulations for modeling separation processes.

“…Moreover, the role of the pressure drop significantly raised as the liquid loads were elevated in the structure packing [48][49][50]. The mass transfer performance and wet and dry pressure drop of the corrugated structured packings were intensively studied [41,[51][52][53][54][55][56].…”

Characterization of New Wire Gauze‐Structured Packing: Experimental Study

Structured packings are usually employed for increasing the surface contact between vapor and liquid in the absorber and distillation of columns. Experimental investigations are performed to present a high-capacity new wire gauze-structured packing, namely, PACK-1300XY, which is the combination of PACK-1300X and PACK-1300Y. The new PACK-1300XY shows improved efficiency of separation and pressure drop. Comprehensive parametric investigations are carried out to calculate the efficiency of mass transfer and the wet/dry pressure drops under different operating conditions. The new wire gauze-structured packing reduces wet and dry pressure drops by more than 10 % in comparison to PACK-1300Y. In addition, PACK-1300XY decreases the height equivalent to a theoretical plate by more than 5 % compared to PACK-1300X.
