Simulation of fine particle formation by precipitation using computational fluid dynamics
Canadian Journal of Chemical Engineering - Tập 78 Số 5 - Trang 983-993 - 2000
Damien Piton, Rodney O. Fox, Bruno Marcant
AbstractThe 4‐environment generalized micromixing (4‐EGM) model is applied to describe turbulent mixing and precipitation of barium sulfate in a tubular reactor. The model is implemented in the commercial computational fluid dynamics (CFD) software Fluent. The CFD code is first used to solve for the hydrodynamic fields (velocity, turbulence kinetic energy, turbulen...... hiện toàn bộ
Orifice Flowmeter for Measuring Extensional Rheological Properties
Canadian Journal of Chemical Engineering - Tập 80 Số 6 - Trang 1189-1196 - 2002
Pierre J. Carreau, Gabriel Ascanio, Edmundo Brito‐de la Fuente, Philippe A. Tanguy
AbstractExtensional rheological properties play an important role in processes in which the fluid is subjected to highly decelerated or accelerated flows. This paper describes an orifice flowmeter used to measure extensional properties of rheologically complex fluids at high strain rates. The operating principle of the flowmeter is based on the pressure drop due to...... hiện toàn bộ
Experimental methods in chemical engineering: specific surface area and pore size distribution measurements—BET, BJH, and DFT
Canadian Journal of Chemical Engineering - Tập 97 Số 11 - Trang 2781-2791 - 2019
Raoof Bardestani, Gregory S. Patience, Serge Kaliaguine
AbstractGas physisorption is an experimental technique based on equilibrium Van der Waals interactions between gas molecules and solid particles, that quantifies the specific surface area (SSA), pore size distribution (PSD), and pore volume of solids and powders. The performance of catalysts, absorbents, chromatography column materials, and polymer resins depends o...... hiện toàn bộ
Removal of reactive blue 19 and reactive blue 49 textile dyes by citrus waste biomass from aqueous solution: Equilibrium and kinetic study
Canadian Journal of Chemical Engineering - Tập 90 Số 2 - Trang 412-419 - 2012
Mahwish Asgher, Haq Nawaz Bhatti
AbstractThe purpose of this study was to establish the potential of inexpensive and locally available biomaterial, that is, lignocellulosic waste of Citrus sinensis as biosorbent to remove reactive anthraquinone dyes from aqueous solution. The effects of immobilisation and chemical treatment of biosorbent were also explored for the enhanc...... hiện toàn bộ
An improved two layer model for horizontal slurry pipeline flow
Canadian Journal of Chemical Engineering - Tập 69 Số 1 - Trang 173-178 - 1991
Randall G. Gillies, C. A. Shook, Kenneth Wilson
AbstractA model for predicting head losses for coarse‐particle or settling slurries has been obtained. Experimental data for isothermal flows of sand, gravel and coarse coal slurries in pipes of industrial scale have been used to obtain the correlations in the model.The model differs from previous versions in the way it deals with the concentration...... hiện toàn bộ
Dispersive‐force modelling of turbulent suspension in heterogeneous slurry flow
Canadian Journal of Chemical Engineering - Tập 66 Số 5 - Trang 721-727 - 1988
Kenneth Wilson, F. J. Pugh
AbstractThe force‐balance model, originally developed for coarse‐particle slurries, has now been extended to slurries of finer particles susceptible to turbulent suspension. The analysis involves a turbulent dispersive force — an equivalent body force between the fluid and solid phases. The use of this force, together with the intergranular stresses for contact‐loa...... hiện toàn bộ
Experiments with concentrated slurries of particles with densities near that of the carrier fluid
Canadian Journal of Chemical Engineering - Tập 63 Số 6 - Trang 861-869 - 1985
C. A. Shook
AbstractExperimental investigations of headlosses and particle velocity distributions have been undertaken for water slurries of polystyrene particles of diameter d50 = 0.3 and 1.4 mm. At concentrations greater than 40–45% by volume, nearly linear headloss vs. velocity relationships were obtained. These suggested lami...... hiện toàn bộ
Porous polymer monolith templated by small polymer molecules
Canadian Journal of Chemical Engineering - Tập 87 Số 4 - Trang 579-583 - 2009
Zhiwang Wu, Kyle Frederic, Mark Talarico, D. De Kée
AbstractPorous poly(ethylene glycol) diacrylate (PEGDA) monoliths have been prepared by UV‐initiated polymerization of PEGDA oligomer (Mn = 700 g/mol). In the mean time, the addition of hydrophobic poly(propylene oxide) (PPO, Mn = 725 g/mol) as porogen into an ethanol so...... hiện toàn bộ
Continuous and oscillatory flow properties of concentrated coal/water suspensions
Canadian Journal of Chemical Engineering - Tập 70 Số 1 - Trang 20-27 - 1992
Romano Lapasin, Sabrina Pricl
AbstractA Theological characterization of coal/water suspensions has been carried out under continuous and oscillatory flow conditions. Shear stress ‐ shear rate data were correlated with the Shangraw‐Grim‐Mattocks (SGM) equation. The analysis of the SGM parameters indicated that a limiting concentration ϕ0 exists above which the suspensions ex...... hiện toàn bộ
The relative exergy array—a new measure for interactions in process design and control
Canadian Journal of Chemical Engineering - Tập 89 Số 3 - Trang 545-549 - 2011
Juan M Montelongo-Luna, William Y. Svrcek, Brent R. Young
AbstractIn this paper, we present the relative exergy array (REA), a tool to measure the relative exergetic efficiency and the controllability of a process when a proposed process and control structure is postulated. The REA is a means to compare thermodynamic efficiency for control structures of multi input–multi output processes. Although only steady‐state inform...... hiện toàn bộ
