Abstract
This project is about the pipeline corrosion caused by the composition of petroleum product in particular crude oil to the internal surface of carbon steel pipeline. Internal and external pipeline corrosion has been the main causes of pipeline failure in oil and gas industry not only in Malaysia but all over the world. However, the internal corrosion is preferred to be concerned in this project because it involved one of the corrosive media in crude oil such as sulfur content. The first objective in this project is to study the sulfur concentration in crude oil by using Fourier Transform Infrared (FTIR) spectroscopy and Atomic Absorption Spectroscopy (AAS). The corrosion rate, corrosion current (Ecorr) and corrosion potential (lcorr) of API X65 grade carbon steel pipeline in different concentration of simulated HzS04 solution were analyzed using Tafel extrapolation method. The corrosion properties on the sample were measured using Optical Microscope (OM), Scanning Electron Microscope (SEM) and Energy Dispersive X-ray (EDX). The results showed that the corrosion rate of carbon steel increased significantly with the increase ofHzS04 concentration. The corrosion products formed on carbon steel surfilces were mainly composed of iron sulfate (FeS04), iron sulfide (FeS) and iron oxide (FeO). These fmdings is important to understand the crude oil corrosivity behavior and should be further investigated the other probability influence factor such as temperature.
