The successful revamp of a conventional tray Xylenes Distillation Column (3800 mm / 4300 mm diameter) is described. The column takes a xylene side-stream from reformate to feed an aromatics plant to make higher value products. Changing the column configuration to a Dividing Wall Column (DWC) resulted in improved product purity and significant energy savings. The project cycle is detailed includ...

We report measurements of the static shear modulus of electrorheological (ER) fluids consisting of water-wetted silica microspheres in silicone oil. A shear-annealing method, using creep-recovery (CR) cycles under an external electric field, is used to enhance ER properties of the fluid. The shear-annealing method enables the silica spheres in the ER fluid to form better aligned and denser colu...

An unsteady analytical solution is proposed to predict the spreading rate of crown generated by an impacting droplet onto wetted walls. The modelling strategy based on direct integration boundary layer correction into potential flow that leads well-established square-root time dependence. original has structure unsteady, stagnation point with decaying strength. For initial strengths $a_0 \geqsl...

In order to study the effect of different gap ratios on thermofluid-dynamic field around a bluff body located in proximity heated wall, series experiments and numerical simulations have been conducted. The former were carried out using an open circulating water tank experimental platform single cylinder square column as geometrical models (their characteristic length being D). latter based well...
