Corrosion Inhibition Investigation of Small Organic Inhibitor on API5LX60 Steel in 3.5% NaCl Solution with CO2 Saturation
CO2 corrosion has emanated as a significant concern in the oil/gas industry owing to the aging of its oilfields. Thus, corrosion protection is significant for maintaining the integrity and sustainability of pipelines, surface facilities, and downhole tools in the oil/gas sector. The present study evaluates the corrosion inhibitory properties of three oxazolone derivatives in CO2 saturated 3.5 weight% NaCl solution against API5LX60 carbon steel used in certain wells and oil/ gas transportation pipelines. The inhibitory behavior was investigated utilizing gravimetric and electrochemical techniques viz. EIS, PDP, and LPR. Electrochemical and Gravimetric technique results were in congruence. EIS asserts capacitive behavior, and PDP affirms oxazolones as mixed inhibitors. SEM and SEM-EDX confirmed the formation of a protective layer by adsorption. At an optimum inhibitor concentration of 200 ppm, inhibitor I exhibited 91.30% inhibition—linear correlation coefficient R2 value of 0.99 avowed adsorptions via Langmuir Isotherm.
期刊介绍：
Biointerface Research in Applied Chemistry is an international and interdisciplinary research journal that focuses on all aspects of nanoscience, bioscience and applied chemistry. Submissions are solicited in all topical areas, ranging from basic aspects of the science materials to practical applications of such materials. With 6 issues per year, the first one published on the 15th of February of 2011, Biointerface Research in Applied Chemistry is an open-access journal, making all research results freely available online. The aim is to publish original papers, short communications as well as review papers highlighting interdisciplinary research, the potential applications of the molecules and materials in the bio-field. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible.
