Computational fluid dynamical studies of structured distillation packings
… industries because of their improved volumetric efficiency. Most structured packings consist of corrugated sheets placed in the vertical plane The corrugations provide a regular network of channels for vapour liquid contact. Until recently it has been necessary to develop new packings by trial …

Further studies on flow distribution on distillation sieve trays
… devices, with the view of enhancing tray efficiency. The mode of operation is based on deflecting part of the liquid momentum from the centre of the tray to the segment regions in order to drive stagnating liquid at the edges forward. The first part of the work was a detailed investigation …

Liquid-liquid Extraction Studies in a Pilot Scale Agitated Column
A study has been made of the hydrodynamics and mass transfer characteristics of the Rotating Disc Contactor. The literature relating to this extractor and relevant phenomena, e.g. droplet break-up and coalescence, single drop mass transfer, axial mixing and phase inversion/flooding, has been …

Desiccant dehumidification analysis
… based on a literature review. The heat and mass transfer in the desiccant - moist air system is well understood and modeled using both pseudo-gas-side controlled (PGC) transfer coefficients and semi-infinite transfer coefficients. Compared with experimental data, the model well predicts …

Gas distribution in shallow large diameter packed beds
… in large diameter packed columns to maintain mass transfer efficiency on scaling up. This work presents measurements and methods of evaluating maldistributed gas flow in packed columns. Little or no previous work has been done in this field. A gas maldistribution number, F, was defined, based …

Using untreated and nanobubble-treated potable and wastewater in mortar
… large surface area, and enhanced gas-liquid mass transfer efficiency, enabling improved interaction with contaminants. In addition, nanobubbles can encapsulate gases like carbon dioxide, presenting potential for carbon capture within cement-based systems. Despite successful applications in …

Development of a novel bioreactor and systems for suspension cell culture in biopharmaceutical production
… In addition, at a large scale, improper mass transfer impairs the performance of cell lines and achieving high cell densities and prolonged viability with correct glycosylation of a secreted proteins is still a challenge during scale-up. Many cell lines, for example Vero cells, which are …
