Processing Red Mud Produced at the Eti Alüminyum A.Ş. Seydişehir Alumina Refinery to Recover Gallium and Vanadium and Obtain Iron Oxide Pigments
Theoretical Foundations of Chemical Engineering - Tập 55 - Trang 797-801 - 2021
R. A. Abdulvaliev, S. V. Gladyshev, B. K. Kenzhaliev, N. K. Akhmadieva, L. M. Imangalieva, A. K. Kasymzhanova
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

Synthesis and discrimination of process flow sheets for the separation of a reaction mixture of methyl tert-butyl ether production
Theoretical Foundations of Chemical Engineering - Tập 49 - Trang 280-286 - 2015
O. N. Krupinova, V. I. Zhuchkov, A. K. Frolkova
Possible process flow sheets for the separation of a quaternary mixture formed in the production of methyl tert-butyl ether were synthesized using different special methods, and the most energy-efficient flow sheet was selected.
Hydrodynamics of a rheologically complicated liquid in a self-cleaning filter
Theoretical 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 gas
Theoretical 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

Separation of an Industrial Mixture of Decalin or Naphthalene Fluorination Products. Physicochemical Foundations of Crystallization of Binary Mixtures of cis- and trans-Perfluorodecalin and Perfluorobutylcyclohexane
Theoretical Foundations of Chemical Engineering - - 2024
A. V. Polkovnichenko, N. N. Kulov, A. V. Kisel’, N. N. Kuritsyn, S. Ya. Kvashnin, E. V. Lunachev
Physical–chemical data on the liquid–solid phase transitions in the binary systems trans-perfluorodecalin (trans-PFD)–cis-perfluorodecalin (cis-PFD), trans-PFD–perfluorobutylcyclohexane (BCH), and cis-PFD–BCH are obtained. All three systems are characterized by the presence of a temperature extremum on the fusibility curve. For the trans-PFD–BCH system, the liquidus line can be described by the eq...... hiện toàn bộ
