Supported photocatalysts for model pollutant degradation and bacterial inactivation

Water quality and bacterial infections are directly related to human health and wellbeing, thus waste water treatment is a necessary procedure for avoiding disturbances to ecosystems and for assuring human health. Furthermore, bacterial contamination in wa ...

Effective Mass-Transfer Area in a Pilot Plant Column Equipped with Structured Packings and with Ceramic Rings

Urs von Stockar

The effective area for mass transfer of the Sulzer structured packing Mellapak 125.Y, 250.Y, and 500.Y was measured under industrial-scale operating conditions, with a broad range of gas and liq. flows, in a pilot plant with a column having an internal dia ...

Gas absorption experiments in a pilot plant column with the sulzer structured packing mellapack

Data for the volumetric mass transfer coefficient, kLa, and the effective area, of structured packings have rarely been reported in the literature. This is despite the ever-increasing importance of structured packings in industrial separation columns for a ...

The influence of viscosity on the liquid-phase mass transfer resistance in packed columns

Urs von Stockar, Xiaoping Lu

The correlations available in the literature cannot be used to est. the liq.-phase mass-transfer coeff. (kL) for viscous solns. Even correlations that agree for water-like viscosities diverge by an order of magnitude for viscosities of only 10 mPa-s. Here, ...
