It is demonstrated that Bayer–hydrogarnet technology can be developed and applied to process red mud for separating important components such as Na2O, Al2O3, Ga2О3, and V2O5 and for obtaining iron oxide pigments from hydrogarnet mud, a product of autoclave leaching of red mud. The process consists of the autoclave leaching of red mud in the presence of lime to produce hydrogarnet mud (3CaO⋅Fe2O3 (...... hiện toàn bộ
Hydrodynamics of a rheologically complicated liquid in a self-cleaning filterTheoretical Foundations of Chemical Engineering - Tập 46 - Trang 594-600 - 2012
V. A. Devisilov, E. Yu. Sharai
A mathematical model has been developed for non-Newtonian flow in a hydrodynamic self-cleaning filter. The system of rheodynamic equations describing the flow of a rheologically complicated medium in the filter has been solved by a numerical method. The velocity and effective viscosity fields for the non-Newtonian liquid have been determined. The effect of the rheological properties of the liquid ...... hiện toàn bộ
Power- and resource-saving process for producing methanol from natural gasTheoretical Foundations of Chemical Engineering - Tập 42 - Trang 12-18 - 2008
E. V. Pisarenko, V. N. Pisarenko, R. M. Minigulov, D. A. Abaskuliev
The processes for producing methanol from syngas and syngas from natural gas are simulated. A kinetic model for the reaction of steam-carbon dioxide reforming of methane that is in good agreement with the experimental data obtained for the ranges of gas hourly gas velocities of 1000 to 10000 h−1, temperatures of 700 to 850°C, and pressures of 0.4 to 2.0 MPa is developed. A power-and resource-savin...... hiện toàn bộ
