Carbon steel pipeline are employed in the transportation of wet natural gas from source to process plant. Corrosion will occur and hydrates may form on the pipeline if not properly protected. In order to protect the pipeline from hydrate formation Monoethylene glycol (MEG) is often used. The continuous use of high pH flow for the gas pipeline can lead to the formation of desirable and undesirable scale formation. Where there are negative effects on the use of high pH the reduction in the pH of the system may be achieved. Alternatively additional measures may be introduced to protect the integrity of the pipeline such as the use of corrosion inhibitor.This paper describes a condition where there is a significant formation of corrosion scale in the form of iron carbonate in wet gas system. The flow assurance on the continuous use of high pH on certain point of the pipeline is considered. Synergistic and antagonistic effect of MEG is the iron carbonate scale is determined with considerations on the use of alternative corrosion protective method.Keywords: CO2 corrosion Monoethylene glycol (MEG) Inhibitor and Iron carbonate scale.

Periodic cleaning of sales gas lines often yields large quantities of material known as black powder. This paper describes a research study that was conducted to provide estimates for corrosion rates of carbon steel in TEG-water mixtures with TEG content in the range 0.0 wt% to 99.5 wt%.
