Additive manufacturing is a promising tool for tailored solutions in chemical engineering. This applies particular to the design of lab-scale packed bed columns. We present experimental results characterize 3D printed structured metal packing and compare it conventional counterpart. The indicate that necessary adjustments process material have an influence on important operating parameters, res...

Abstract This work considers the method of corrugated sheet arrangement near column wall with aim to limit liquid fall on and increase concentration in near-wall area. Experiments were carried out at Koch 1Y packing sheets for various flow rates. report presents experimental results character edge effect middle shift from packing. The ribs this are directed downward Test was performed two posit...

Abstract Dividing-wall columns(DWC) are intensified distillation systems for multicomponent separations. They have the potential to save both energy and capital costs significantly than conventional simple column configurations. The several DWC columns for ternary distillations have been figured out by some creative activities from different inventors. Recently they have gained the momentum to ...

To improve the utilization rate of bamboo, glued laminated bamboo hollow column (GLBHC) was examined under eccentric compression to study effects different slenderness ratios, distances, and wall thicknesses on its ultimate bearing capacity. The nonlinear deformation material P-delta effect occur compression, which can affect capacity, so it is very important analyze elastic-plastic buckling co...

from chitinase hydrolyzate of the fungal cell wall by CM-Sephadex C-25 column chromatography, while (GlcNAc)2 and seyeral types of deacety]ated chitooligosaccharides were separated from that of 2S---35% acetylated chitesan. The results indicate that ?VLacetylglucosamine residues in the pelysaccharide chains of the fungal cell waR are most likely condensed into some region, while acetylated resi...

This study aims to investigate the impact of soil-structure interaction (SSI) on seismic behavior reinforced concrete buildings. An advanced numerical model for SSI was developed and verified using ABAQUS software. The response a 12-story building four types soil (rock, dense soil, stiff soft soil) examined Normalized Response Spectra based Moroccan paraseismic regulation RPS 2011. global later...

Experiments and computational simulations are carried out to study the behavior of a granular column in a silo whose walls are able to vibrate horizontally. The column is brought to a steady fluidized state and it behaves similar to a hydrostatic system. We study the dynamics of the granular discharge through openings at the bottom of the silo in order to search for a Torricelli-like behavior. ...

The "Petlyuk" or "dividing-wall" or "fully thermally coupled" distillation column is an interesting alternative to the conventional cascaded binary columns for separation of multi-component mixtures. The industrial use has been very limited, and difficulties in control has been reported as one reason. Since we have more manipulated variables than controlled variables, the column is a candidate ...
