Uticaj strukture na sposobnost oblikovanja Al-Mg6,8 legure / Influence of microstructure on the formability of Al-Mg6.8 alloy
(Association of Chemical Engineers of Serbia, 2008)
U ovom radu korišćena je aluminijum-magnezijum legura sa 6,8% magnezijuma (Al-Mg6,8), koja pripada grupi Al-Mg legura visoke čvrstoće. Ispitivan je uticaj mikrostrukture, koja se postiže primenom različitih uslova ...
The antioxidant properties of dried extracts from spent espresso coffee / Antioksidativna svojstva sušenih ekstrakata iz otpadne espreso kafe
(Association of Chemical Engineers of Serbia, 2013)
The importance of coffee waste utilization is based on the fact that it contains a large amount of biologically valuable components. Preparation of espresso coffee produces substantial quantities of polyphenolic acids that ...
Effects of operating parameters on efficiency of lead removal by complexation-microfiltration process / Uticaj radnih parametara na efikasnost uklanjanja jona olova pomoću kompleksirajuće-mikrofiltracionog procesa
(Association of Chemical Engineers of Serbia, 2012)
The majority of lead content found in the environment is a result of human activities. Heavy metals can be hazardous because they tend to bioaccumulate. A complexation-microfiltration process for the removal of Pb(II) ions ...
Energy integration of nitric acid production using Pinch methodology / Energetska integracija proizvodnje azotne kiseline primenom Pinch metodologije
(Association of Chemical Engineers of Serbia, 2015)
Pinch methodology was applied to the heat exchangers network (HEN) synthesis of nitric acid production. The integration is analyzed in two ways, and the results are presented as two different solutions: i) the first solution ...
Economizer water-wall damages initiated by feedwater impurities
(Savez hemijskih inženjera, Beograd, 2014)
The main causes of efficiency loss in thermal power plants are boiler tube failures that diminish unit reliability and availability, and raise the cost of the electric energy. For that reason, the regular examination of ...
Application of lignocellulolytic fungi for bioethanol production from renewable biomass / Primena gljiva koje razgrađuju lignocelulozu za proizvodnju bioetanola iz obnovljive biomase
(Association of Chemical Engineers of Serbia, 2015)
Pretreatment is a necessary step in the process of conversion of lignocellulosic biomass to ethanol; by changing the structure of lignocellulose, enhances enzymatic hydrolysis, but often it consumes large amounts of energy ...
A new procedure for the treatment of an industrial waste containing flotation reagents / Novi postupak prerade industrijskog otpada koji sadrži flotoreagense na bazi ksantata
(Association of Chemical Engineers of Serbia, 2014)
Flotation reagents can be transformed to industrial waste if they are stored for a long period of time. Also, if synthesis or drying process is not performed under defined conditions in industrial plants, which produce ...
