PEMANFAATAN LIMBAH AMPAS TEBU SEBAGAI INHIBITOR KOROSI BAJA St. 37 DALAM MEDIUM ASAM KLORIDA
Abstract: Refer to the main
problems in oil and gas industry that is corrosion, the experiment to inhibit a
corrosion process was
done. Bagasse which
known has a
high enough number
of lignin and potency
to inhibit corrosion
process was used
in this experiment.
Lignin extraction from bagasse
and weight loss
method to obtain
the efficiency inhibition
was done. Besides, immersion of
steel St. 37 in 1
M hydrochloric acid
solution with variation
temperature (30, 40, 50,
60oC) was done
to obtain the
activation energies. Measurement
with potentiodynamic polarization was done to
observe the corrosion rates based on the polarization curve. Analysis of
photooptic was done also to see the steel surface with and without inhibitor.
According to the experiment, the efficiency inhibitor
was observed to
increase with increase
in concentration of extract
but decrease with
temperature. The optimum
temperature was 50oC
for optimum efficiency.
Efficiency ranged between 85,92% - 91,61% and 51,83% - 92,20% for
potentiodynamic polarization with optimum of extract concentration is 0,9%..
Activation energy was 62,7 kJ/mol. The
result of photooptic
analysis showed the
difference of steel
surface with and
without inhibitor.
