| Summary: | Corrosion is decreasing of metal quality which is caused not only by direct contact
with corrosive environment but also can be induced by microorganism. In the oil and
gas company, crude oil and wet gas are flown by carbon steel from drilling well to
processing. Control of corrosion happened on the surface steel of pipeline is done by
addition of corrosion inhibitor continually. Generally, organic compounds contained
nitrogen, sulfur and oxygen are their binding anchor on the surface of metal.
Penicillin and its derivatives are well-known as antibiotics, have three elements on its
molecule so can be strongly absorbed on carbon steel surface. This research used
amoxicillin and ampicillin as corrosion inhibitor. Corrosion inhibition tests were
done by corrosion wheel test, electrochemocal impedance spectroscopy and Tafel
method with variation of temperature amd concentration of inhibitor. Result of
corrosion inhibition test for penicillin derivatives on the 55oC is 10 ppm amoxicillin
having the highest inhibition with inhibition efficiency reached 83,00%. |
