Optimization of Oxidation Desulphurization of Power-generating Coal

An experimental statistic model of power-generating coal oxidative desulphurization has been developed and its adequacy has been proved. On the basis of the proposed model the desulphurization optimal conditions for three samples of power-generating coal were determined. The low-sulphur solid fuel with the content of general sulphur of 1.0–1.5 mas % was obtained under established optimal conditions.

Hydrodynamics Modeling of Gas Separator Inertial and Filter Elements for Natural Gas Fine Cleaning

The trends in the development of modern gas separation equipment have been considered. On the basis of computer modeling the optimal size of the device has been obtained. Reasonable choice of a computer and mathematical experiments, as a research method has been shown. The experimental results of the double-circuit dust collector investigations have been represented.

Analysis of the Conditions of Phase Equilibrium and Influence of the United Heat and Mass Transfer on the Effectiveness of Separation in the Inertial-Filtering Separator

In this paper the basic thermodynamic parameters that have the greatest impact on the efficiency of the separation processes of gas-liquid mixtures and phase equilibrium in such systems are considered. The general characteristics of separation processes based on phase equilibrium are given. The main approaches to the calculation of phase equilibrium and coupled heat are analyzed. Possible ways of gas separation technology improvement and development are explored.

Study of Mass Transfer Coefficient of Cephalexin Adsorption onto Walnut Shell-Based Activated Carbon in a Fixed-Bed Column

The adsorption of cephalexin (CFX) onto walnut shell-based activated carbon (AC) was investigated. The mass transfer coefficients were calculated by employing constant wave propagation theory. The effect of different conditions on the mass transfer coefficient was also studied. In addition, three models to predict the mass transfer coefficient were developed.
