• A feasible path-based procedure allows to bypass the simulation failures due non-ideal thermodynamics or complex optimization algorithms. The proposed use a shortcut design provided by ProSimPlus® process simulator initialize algorithm coupled with rigorous simulations. Although “non-optimal”, DWC obtained via fulfills expectations both from an economic and environmental point of view respect...

The distillation process remains as the most common method ofseparation in chemical process industries. The energy used from this process accounts for an estimated 3% of <span style="font-size: 10pt; c...

Dividing-wall columns (DWCs) are intensified processes that have attracted industrial and academic attention due to the reduction in operating installation costs compared traditional distillation systems. Several methodologies available for design of DWCs. Most them consist three parts: an analysis variables; structural (topology); optimization resulting preliminary design. This paper aims stud...

By analyzing the monitoring data of excavation foundation, maximum lateral displacement depth and top vertical retaining wall, column are studied. Research indicates that 3rd power polynomial curve can better fit change law deformation wall at each point；the fourth support demolition has great influence on wall. The third layer greatly increased After second is removed, to negative. gradually d...

virulence of the opportunistic yeast, candida albieans, involves the interplay of many complex changes including the yeast-hyphae transition, which mainly involves protein changes. cell wall mannoproteins are found to be the main cause of adherence of c. albieans to epithel ial cells in the first step of an infection process. in the present study, cell wall mannoproteins of intact yeast were pu...

A 5-amino-8-hydroxyquinoline (AHQ)-modified gold nanoparticle (GNP) layer was fabricated on an inner wall of a silica capillary column by alternatively passing a citrate-stabilized GNP solution and an AHQ solution in a repeating fashion. The observations by a field emission scanning electron microscope showed that the thickness of the resulting GNP layer was about 0.15 microm. This column was t...

The excitation of ion azimuthal surface oscillations with extraordinary polarization by light ion beam is studied analytically. Beam-plasma system consists of a cylindrical metal waveguide filled partially by cold magnetized plasma and light ion flow rotating around the plasma column. Dependencies of the beam instability growth rate on the system parameters (plasma and beam densities, value of ...
