“…Investigations and experimental work aimed at further improving the performance of various distillation columns have been carried out by many researchers for many years, accompanied by ongoing advances and improvements in this technology [1][2][3][4][5][6]. The current situation with respect to their design and scale up seems closer to maturity from a technological point of view.…”

With a particular focus on the distillation of highly viscous or self-polymerized mixtures, this study reports the hydrodynamic and mass transfer performance of two flow-guided sieve trays, including their pressure drop, entrainment, weeping and tray efficiency, obtained experimentally with an air-water/oxygen system in a Φ600 mm plexiglass column. The results show that the 8 mm hole flow-guided sieve tray tested shows better characteristics than the 7 mm flow-guided hole tray in terms of pressure drop and mass transfer. Then we present practical industrial examples of applications of the flow guided trays for distillation of viscous mixtures, i.e., the separation of vinyl acetate (VAC) from a polyvinyl acetate (PVAC) polymer solution with dynamic viscosity μ=50,000 mPas, the separation of highly unsaturated C5 mixtures by extractive distillation, and the distillation of thick, condensed and highly viscous fermentation mixtures made from fermented mash. It is demonstrated that flow-guided sieve trays with relatively large holes are an excellent candidate for distillation of mixtures with suspended solids, or concentrated/self-polymerized polymer solutions.

“…This is simply because there was no unit assigned to refine the middle product. This can be overcome by creating a larger system (superstructure) consisting of sequential separation units [140,141]. This superstructure then requires at least two splitting units and three refining units.…”
