Estimation of evaporative losses during storage of crude oil and petroleum products / Kvantifikacija evaporativnih gubitaka nafte i naftnih derivata tokom skladištenja
(Association of Chemical Engineers of Serbia, 2013)
Storage of crude oil and petroleum products inevitably leads to evaporative losses. Those losses are important for the industrial plants mass balances, as well as for the environmental protection. In this paper, estimation ...
Testing the protective efficiency of personal respiratory protection devices in radiologically contaminated environments / Ispitivanje efikasnosti sredstava lične respiratorne zaštite u uslovima radiološke kontaminacije životne sredine
(Vinca Institute of Nuclear Sciences, 2013)
The use of ammunition primed with depleted uranium is one of the hallmarks of modern combat operations, resulting in environmental contamination by particles of depleted uranium and uranium oxide, scattered around in the ...
VOC emission from oil refinery and petrochemical wastewater treatment plant estimation / Procena emisija lakoisparljivih organskih jedinjenja iz postrojenja za primarni tretman otpadnih voda rafinerijskih i petrohemijskih postrojenja
(Association of Chemical Engineers of Serbia, 2013)
As a consequence of environmental legislation improvement in Serbia for industrial producers, especially future holders of Integrated Pollution Prevention Control (IPPC) license, it is necessary to report annually on ...
Unique effects of microwave heating on polymerization kinetics of poly(methyl methacrylate) composites
(Elsevier Science Sa, Lausanne, 2013)
The effects of heating mode (conventional and microwave) on the kinetics of isothermal polymerization of MMA composite materials were investigated. Isothermal kinetics curves at temperature range from 343 K to 363 K for ...
Potential of Trametes species to degrade lignin
(Elsevier Sci Ltd, Oxford, 2013)
Well developed ligninolytic enzyme system in white-rot mushrooms is responsible for degradation of low degradable and lignin rich unused plant debris, which represents serious environmental ballast. The biological degradation ...
