Tests confirm effectiveness of new inhibitor for pipeline internal corrosion

Comparative tests of commercially available corrosion inhibitors revealed that a new corrosion inhibitor, IMP-ICCA-9710, presented a higher protection efficiency in corrosion protection. Inhibitors were evaluated in rust, electrical resistance probe, bottle, and dynamic circuit (loop) tests; in the latter one, electrochemical and weight loss techniques were used, observing a good correlation in both cases.The IMP-ICCA-9710 inhibitor turned out to be excellent for pipeline protection against corrosive agents in crude oil, displaying a protective film that adheres to the metal surface for long periods. The inhibitor is an imidazoline type and dispers able in water and soluble in hydrocarbon...
