Corrosion Rate Analysis of API 5L Gr B Steel Pipe in Acetic Acid Contained Crude Oil Treatment System by Using Amine Base Organik Corrosion Inhibitor

Abstract:

Corrosion is the main problem in the processing of crude oil containing soap emulsion by using acetic acid based demulsifier. This study aims to analyze corrosion of API 5L Gr B steel pipe in the solution of 90% brine and 10% crude oil with addition of 2000 ppm of acetic acid based demulsifier at various concentration of amine based organic inhibitor. Corrosion testing was conducted using weight loss coupon. SEM and EDS analysis were performed to investigate corroded specimen. The weight loss results indicate that amine based organic inhibitor made the steel resistant to corrosion with an inhibitor effectiveness of up to 96.67% at a concentration of 40 ppm. SEM observation following with EDS analysis identifying the presence of inhibitor and corrosion product protection layer.
