Abstract
Use of organic surfactant corrosion inhibitors provides an economical and effective way for internal corrosion control of oil and gas production and transportation pipelines. Corrosion inhibition measurements using electrochemical techniques can be used to evaluate the efficacy of corrosion inhibitors based on steady state corrosion rates. The corrosion behavior with respect to time can further be utilized to quantify adsorption kinetics of inhibitor molecules on metal and can further be integrated in the development of corrosion prediction tools. However, corrosion rates measurements can be very sensitive to experimental methodology in the presence of corrosion inhibitors in the test solution, and repeatability is often difficult to achieve if a robust methodology is not followed meticulously. In this study, the importance of the location of inhibitor addition in lab-scale corrosion experimentation is discussed.
期刊介绍:
CORROSION is the premier research journal featuring peer-reviewed technical articles from the world’s top researchers and provides a permanent record of progress in the science and technology of corrosion prevention and control. The scope of the journal includes the latest developments in areas of corrosion metallurgy, mechanisms, predictors, cracking (sulfide stress, stress corrosion, hydrogen-induced), passivation, and CO2 corrosion.
70+ years and over 7,100 peer-reviewed articles with advances in corrosion science and engineering have been published in CORROSION. The journal publishes seven article types – original articles, invited critical reviews, technical notes, corrosion communications fast-tracked for rapid publication, special research topic issues, research letters of yearly annual conference student poster sessions, and scientific investigations of field corrosion processes. CORROSION, the Journal of Science and Engineering, serves as an important communication platform for academics, researchers, technical libraries, and universities.
Articles considered for CORROSION should have significant permanent value and should accomplish at least one of the following objectives:
• Contribute awareness of corrosion phenomena,
• Advance understanding of fundamental process, and/or
• Further the knowledge of techniques and practices used to reduce corrosion.
