Performance Evaluation of a Full-Scale Deep U-Tube Utilizing Ozonated Oxygen as the Process Gas for Treating Drinking Water [PDF]

open access: yes, 2007
A deep U-tube for treating drinking water is composed of a coaxial inner tube serving as an efficient concurrent down-flow ozone dissolver and an outer column carrying out reactions between ozone and organic substances dissolved in the water after ...

Numerical Investigation into Effects of Gas Sparger and Horizontal Baffles on Hydrodynamics of Flat Bubble Column

open access: yesChemEngineering
Computational fluid dynamics (CFD) was used to investigate influence of different gas sparger configurations and the presence of horizontal baffles on hydrodynamic characteristics in a flat bubble column. CFD results of time-averaged local and global gas

Interfacial shear in adiabatic downward gas/liquid co-current annular flow in pipes [PDF]

open access: yes, 2015
Interfacial friction is one of the key variables for predicting annular two-phase flow behaviours in vertical pipes. In order to develop an improved correlation for interfacial friction factor in downward co-current annular flow, the pressure gradient ...

CFD-PBM Coupled Simulation of an Airlift Reactor with Non-Newtonian Fluid

open access: yesOil & Gas Science and Technology, 2017
Hydrodynamics of an AirLift Reactor (ALR) with tap water and non-Newtonian fluid was studied experimentally and by numerical simulations. The Population Balance Model (PBM) with multiple breakup and coalescence mechanisms was used to describe bubble size

Performance characteristics of a new structured packing [PDF]

open access: yes, 2010
A new structured packing using carbon fibres, called Sepcarb® 4D, is presented. This packing has several attractive properties, such as high voidage (ε=94%) and high effective area (a=420 m2 m−3).

Deviations of Fischer-Tropsch products from an Anderson-Schulz-Flory distribution [PDF]

open access: yes, 1988
Negative deviations from an Anderson-Schulz-Flory distribution have been observed for the product of the Fischer-Tropsch synthesis. The catalyst was a complex-derived iron-calcium catalyst promoted with cesium sulphate, therefore, neither carrier acidity

Mechanistic modeling of pollutant removal, temperature, and evaporation in chemical air scrubbers [PDF]

open access: yes, 2016
Chemical air scrubbers reduce the concentration of water-soluble components such as ammonia from the outgoing ventilation air through absorption in water, followed by chemical conversions and removal of the end products.
