New corrosion inhibitor passes tests on Pemex crude line

Pemex Refinacion, part of Petroleos Mexicanos (Pemex) and operator of more than 4,100 km of crude oil pipelines in several diameters, has tested a newly developed corrosion inhibitor on 30, 24, and 20-in. OD pipelines on a 220-km extension. The inhibitor, IMP-ICCA-9710, is manufactured and marketed...

Description
Summary:Pemex Refinacion, part of Petroleos Mexicanos (Pemex) and operator of more than 4,100 km of crude oil pipelines in several diameters, has tested a newly developed corrosion inhibitor on 30, 24, and 20-in. OD pipelines on a 220-km extension. The inhibitor, IMP-ICCA-9710, is manufactured and marketed by Pemex. During the evaluation period, a 100% increase in crude salt content was also observed at the end of the evaluation line. Evaluation of the corrosion inhibitor additive showed a reduction in corrosion velocity, compared over the same period of time with no inhibitor. Increasing the corrosion inhibitor's concentration further decreased corrosion velocity. At 4-ppm concentration, IMP-ICCA-9710 proved to be 1.7 times more efficient than IN-3 inhibitor, another product manufactured and marketed by Pemex, which was in use at the time of the tests.
