Braskem units always seek to
minimize their environmental
impact. To this end, they work to
find alternatives that help reduce
energy consumption, improving
efficiency, and searching for the
best available energy matrix.
The result for the year was
in line with the agreed upon
target for 2016 (10.25 GJ/t),
and 2.3% below the 2015
performance (10.49 GJ/t). It
was Braskem's best historical
result for the indicator and a
total reduction of 14% since the
beginning of measurement in
2002. Among the actions that
contributed to this result are the
energy optimization initiatives
for furnaces, boilers, turbines,
pumps, and compressors, better
energy utilization in the plants,
greater efficiency in steam
generation, and the development
of control systems.

Note: Braskem Idesa's consumption in Mexico was not recorded in 2016, since
the Complex was at the beginning of its operation and in the stabilization phase.
Beginning in 2017, the unit's consumption will be part of the indicator.
Among the main initiatives in
Brazil toward reducing energy
consumption in the units, the
following stand out:
ALAGOAS - PVC2 AL
Savings of BRL 1.7 million per
year through reduced vapor
consumption in the MVC T
1302 and T1502 purification
column, with a reduction in CO2
emissions of 3.4 kg/t MVC/day.
In addition, the plant managed
to reduce consumption by 1.2
t/h of steam in the P3201A/B
and P3206 heat exchangers,
reducing CO2 emissions (savings
of BRL 657,000 per year) and
steam consumption through
energy optimization, with a
1.13 million m³ drop in water
consumption and 1.11 million m3
drop in natural gas consumption
(savings of BRL 1.2 million per
year).
SÃO PAULO - PP3 ABC
Savings of BRL 900,000 avoiding
the burning of 320,000 kg of
hydrocarbons by the Flare.
The result was a reduction in
greenhouse gases emissions
equivalent to 1,100 t of CO2.View entire presentation
