Since the entry of natural gas into the refi nery’s fuel pool,<br />
in 2008, it has been observed a signifi cant decrease in the<br />
consumption of RFO, as it may be verifi ed in the charts.<br />
In <strong>2011</strong>, RFO consumption has decreased about 11% compared<br />
to consumption during the year 2010. This decrease is due in<br />
part to natural gas increased consumption in <strong>2011</strong> which was<br />
79,064 tons, compared to 45,338 tons consumed in 2010.<br />
As far as electricity is concerned, the refi nery sells or acquires<br />
electricity from the city network depending on whether there<br />
is surplus or shortage. The following graph shows the electricity<br />
produced and consumed.<br />

Sulfur is a natural component of crude oil. During the refi ning<br />
process it is possible to recover a great part of this element, but<br />
a residual portion is retained in refi ned products. When these<br />
are used as fuel, sulphur is released into the atmosphere.<br />
