The effects of operating conditions on the pressure variation at the bottom of a 16.6 cm I.D. reciprocating plate column / Uticaj operativnih uslova na promenu pritiska na dnu kolone sa vibracionom mesalicom prečnika 16,6 cm
(CI and CEQ, 2005)
The effects of the intensity of vibration, superficial gas velocity, content of solid particles and rheology of the liquid phase on the total and time-averaged pressure variation at the bottom of a 16.6 cm i.d. reciprocating ...
Correlation between chemical composition of the γ-Bi2O3 phase and the properties of ZnO varistors
(Chemical Industry and Chemical Engineering Quarterly, 2005)
Four varistor samples differing in chemical and phase composition of the starting Bi2O3 phase were prepared by the method of direct mixing of the constituent phases (DMCP), i.e. by sintering the mixture of the previously ...
Removal of mineral oil and wastewater pollutants using hard coal
(Association of Chemical Engineers of Serbia, 2009)
This study investigates the use of hard coal as an adsorbent for removal of mineral oil from wastewater. In order to determine the efficiency of hard coal as an adsorbent of mineral oil, process parameters such as sorption ...
Models of an asphaltene aggregate and a micelle of the petroleum colloid system
(CI and CEQ, 2000)
Using recent proposals for the hypothetical structure of an average asphaltene molecule and the results of determining the dimensions of asphaltene molecules and aggregates, a model of the asphaltene aggregate (nucleus) ...
Heat of vaporization from the corresponding states principle / Određivanje toplote isparavanja na bazi principa korespondentnih stanja
(Association of the Chemical Engineers of Serbia, 2005)
The heat of vaporization was estimated from the corresponding states principle. The reported values of the functions δS(0) and δS(1), or their analytical expressions, are presented. Tabulated values of δS(0) and δS(1) were ...
Automated learning and control using speedup and neural networks
(CI and CEQ, 2000)
This paper studies complex dynamic neural network learning models. Backpropagation was used to train a neural network for dynamic simulation and control of a chemical stirred tank. The generalized delta rule algorithm was ...
Chemical plant fault diagnosis by neural networks / Dijagnostika kvara hemijskog postrojenja pomoću neuronskih mreža
(CI and CEQ, 2000)
An analysis of learning and generalization characteristics of neural networks for diagnosing process failures was presented. Various feedforward neural network topologies were tested and compared. The single fault assumption ...
Contribution of textile technology to the development of modern compression bandages
(CI and CEQ, 2007)
Although compression therapy is a key factor in the successful treatment of some circulatory problems in lower limbs, this form of therapy includes some risks if used inappropriately. Based on deliberate application of ...
Fenomeni prenosa elektrona i količine kretanja na razvijenim deformabilnim i rigidnim međupovršinama tečno-tečno / Electron and momentum transfer phenomena at developed deformable and rigid liquid-liquid interfaces
(Savez hemijskih inženjera, Beograd, 2006)
Primenjena je nova ideja za rasvetljavanje fenomena prenosa elektrona i količine kretanja na razvijenim, deformabilnim i rigidnim, međupovršinama u finim (mikro, nano, ato) disperznim sistemima. Ponašanje elektroviskoelastičnih ...
Ozone absorption in raw waters
(Serbian Chemical Society, 2008)
The ozone absorption in raw water entering the main ozonization step at the Belgrade drinking water supply plant was investigated in a continuous stirred tank reactor (CSTR). A slow chemical reaction rate of dissolved ozone ...
