Beneficiation of Phosphates VII

Tenova Bateman Technologies (TBT), part of Tenova Mining & Minerals is known as a provider of advanced process technologies in solvent extraction, phosphate beneficiation and fertilizer production.

TBT has participated in a number of phosphate projects and offers a comprehensive range of phosphate treatment technologies: from beneficiation to the production of purified phosphoric acid and downstream salts.

The beneficiation of phosphate rock can often be simplified and made more economic by taking into account the distribution of P₂O₅ and impurities as a function of their deportment between the size fractions resulting from mined and comminuted sedimentary phosphates. …

Numerical Solution Of Burgers' Equation Arising In Longitudinal Dispersion Phenomena In Fluid Flow Through Porous Media By Crank-Nicolson Scheme, Ravi Borana, Vikas Pradhan, Manoj Mehta

5th International Conference on Porous Media and Their Applications in Science, Engineering and Industry

The present paper discusses the numerical solution of the Burgers’ equation arising in longitudinal dispersion phenomenon in fluid flow through porous media. In the porous medium pure water, salt water or contaminated water disperse in longitudinal direction gives rise to a non-linear partial differential equation in the form of Burgers’ equation. The equation is solved by using Crank-Nicolson finite difference scheme with appropriate initial and boundary conditions. The longitudinal dispersion phenomenon may be miscible or immiscible fluid flow through porous media. The problem of miscible displacement can be seen in the coastal areas, where fresh water beds are gradually displaced …

Evaporation From A Capillary Tube: Experiment And Modelization, Emmanuel Keita, Pamela Faure, Stephane Rodts, Phillippe Coussot, David Weitz

5th International Conference on Porous Media and Their Applications in Science, Engineering and Industry

Drying is known to play a major role in soils and buildings materials. Better understanding the physics may help saving cost and energy. Thus control of the drying kinetics is a key factor. In permeable porous media, capillary forces lead to constant curvature of the air/water interface. The value of the curvature and the shape of the interface depend strongly on the pore geometry. Thus small change in their shape may lead to main change of the air/water interface as the medium desaturates. As the surface is supplied with water the drying rate remains at a constant value set by …

Experimental Study For Air Cooling Using Membrane Covered Tray, Mohamed Ali, Obida Zeitoun, Hany Al-Ansary, Abdullah Nuhait

5th International Conference on Porous Media and Their Applications in Science, Engineering and Industry

An experimental study is conducted to cool the outdoor air using a humidification technique. A wind tunnel was built with a membrane covered tray serves as a test section. An outdoor air passes over a tray full of water and covered with a specific membrane. Air temperatures and relative humidity are measured before and after the tray for several air and water speeds. Air speed is measured at different locations along the centerline of the cross section. Results show that as the angle of the tray increases the air temperature drop increases which improve the efficiency of the humidification technique. …

Prediction Of The Cyclic Durability As A Function Of Cycle Duration And Temperature Of An Air Plasma Sprayed Coating Using Inelastic Strain, Eric H. Jordan, Shayan Ahmadian, Maurice Gell

Thermal Barrier Coatings IV

A detailed study of the failure mechanisms in an APS TBC was carried out involving over 1000 micrographs. As a result the kinetics of oxidation and rumpling were characterized. In addition it was found that the failure was always within the ceramic caused by progressive cracking. At approximately half the spallation life, crack linking became the dominant growth mode for cracks. This pattern of damage remained constants over the temperature range of 1066 °C to 1149 °C and for cycle durations of 0.5 hours to 50 hours. The change in temperature resulted in a variation in spallation life of a …
