Application of interval-simplex method for description of chemical reactions kinetics

Article preview

An interval-simplex method of transforming kinetic equations of various degrees of complexity into a form convenient for practical engineering calculations to determine the parameters included in these equations is considered. This method allows to transform kinetic equations into a dimensionless form using simplex similarity. Representations of the interval-simplex method for transformation of equations describing regularities of kinetics of heterogeneous and homogeneous chemical processes of dissolution, leaching, as well as complex autoclave processes are considered.

Model of technology of limestone roasting in a shaft kiln

Article preview

The mathematical description of the technology of firing of lump limestone raw materials in a shaft kiln equipped with burner devices providing preliminary gas combustion is given. The model takes into account the peculiarities of the process of dissociation of carbonate component of raw materials, uses equations describing the kinetics of the drying process, conditions of counter-flow of gases and material, regularities of distribution of material and gas flows along the cross-section and height of the shaft. The developed model represents a stationary two-dimensional solution of the problem.

Application of press filters at the stage of copper-nickel concentrates dehydration

Article preview

The paper describes the operation and control system of modern press filters on the example of LaroxPF filters installed in the roasting shop of Pechenganickel Combine. The main problems of improving and optimizing the operation of press filters are identified and a method of their solution is proposed by drawing up regression dependencies for the main characteristics of filter operation based on experimental data.
