each step. The analysis is carried out on the basis of data directly collected in
SELEKTİF TEKNOLOJİ Co. Inc. Ltd. The work is realised in collaboration with
Marmara University Engineering Faculty.
Selective surface is made of electrochemically treated and coated copper sheet
(thickness:0.001 m, width: 1 m). A copper roll is treated to obtain solar selectivity
in a continuous system. 1m per minute is assumed as flow rate. 4400 hours per year
is assumed as system production time for 250.000 m 2 selective surface production.
All the treatment baths are made of polypropylen.
The direct mean power consumption during production process ( 18 kW for pretreatment
of the surface, 28 kW for coating and 7 kW for nano coating, thermal
treatments and rolling) was 50 kW . A building of 300 m 2 with two floor is assumed
for factory plant
10% of the product is accepted as wastes. Wastes will be delivered to a company
that take care about disposal. 95% of the selective surface would be recycled in
their end-life.
All the calculation is realized using Sima Pro LCA programmes.
The energy analysis concerns with the energy flows occurring during life cycle of
the product.
