DETERMINATION OF THE ENERGY PERFORMANCE OF THE CHP DANUTONI INSTALATION (Papers SGEM2018)

D. C. Petrilean, M. D. Racs, B. I. Gaita
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Cogeneration is one of the current solutions for the use of secondary thermal resources consisting in the simultaneous supply of electric and thermal energy. The main advantage of cogeneration is the use of thermal energy discharged from industrial installations. The type of (...)


DOPED NANOSTRUCTURED CARBONIC MATERIALS FOR HYDROGEN STORAGE - A COMPARATIVE RESEARCH (Papers SGEM2018)

R. Mirea, G. Rimbu, M. Iordoc
Thursday 11 October 2018 by Libadmin2018
ABSTRACT A comparative research related to hydrogen adsorption capacity of multi wall nanotubes (MWNTs) and poly aniline (PANI) doped with Ruthenium (Ru) was carried out. Carbonic materials are considered to be one of the most promising materials for hydrogen adsorption and storage; they have (...)


ECO- EFFICIENT AND NATURAL REFRIGERANTS -THEORETICAL STUDY CASE (Papers SGEM2018)

G. M. Tarlea, M. Vinceriuc, I. Zabet, A. Tarlea
Thursday 11 October 2018 by Libadmin2018
ABSTRACT To implement the International Legislation, in the future it is necessary to retrofit HFC refrigerants with ecological ones. Minimizing the presence of F-gases deriving from activities in the field of refrigeration in the atmosphere, air-conditioning systems and heat pumps can only be (...)


ECO-FRIENDLY RECOVERY OF COPPER FROM WASTEWATER BY CEMENTATION (Papers SGEM2018)

C. ROBA, I. PISTEA, O. ILCIUC, C. ROSU
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Cementation is one of the most effective, eco-friendly and economically advantageous techniques for removal of valuable and / or toxic metals from industrial wastewaters. Copper is among the most prevalent and valuable metal used in industry. The present study investigates an (...)


ECO-TOXICITY OF CHICKEN MANURE DERIVED BIOCHARS (Papers SGEM2018)

K. Dzhabarova, P. Kuryntseva, P. Galitskaya, S. Selivanovskaya
Thursday 11 October 2018 by Libadmin2018
ABSTRACT High concentrations of ammonium, toxic organic compounds, pathogenic microflora make chicken manure one of the most toxic agricultural wastes. The use of chicken manure in plant growing is only possible after its treatment, e.g. by means of composting or anaerobic digestion. One of (...)


EFFECT OF RAW MATERIAL COMPOSITION ON PELLETS PHYSICAL PROPERTIES (Papers SGEM2018)

P. Krizan, M. Matus, J. Beniak, J. Babics
Thursday 11 October 2018 by Libadmin2018
ABSTRACT This manuscript concentrates on the relationship between pellets quality, which is represented by the pellets physical properties, and the input composition of raw material. The main aim of this study is to determine the relationship between the raw material composition, which (...)


EFFECTIVENESS OF SHIPS PROPULSION OPERATING ON THE ALTERNATIVE FUELS TO HYDROCARBON FUELS. (Papers SGEM2018)

Z. Losiewicz
Thursday 11 October 2018 by Libadmin2018
ABSTRACT In this paper relationships of vessels and the environment, in which exploitation tasks are carried out, were presented. It was shown how important is rational choice of propulsion unit to construct a vessel which should be provided with proper energy to do the tasks given. Vessels (...)


ENERGY EFFICIENCY FOR RENEWABLE ENERGY APPLICATION (Papers SGEM2018)

I. C. Hoarca, F. M. Enescu, N. Bizon
Thursday 11 October 2018 by Libadmin2018
ABSTRACT In this paper it is proposed a Hybrid Power Source (HPS), based on Renewable Energy Sources (RES), and a Fuel Cell (FC) system as backup energy source, which uses an optimal control strategy for the fueling rates of the FC (hydrogen and air) based on the load following (LF) control. (...)
