Solubility measurements of corrosion products

Corrosion is a well‐known problem and has led to production losses, equipment failures and costly shut downs.

Addressing the corrosion problem of the pipeline infrastructure will reduce costs on equipment failures and minimize the risk of production loss.

One of the methods to reduce the corrosion in pipelines is the control of pH. Inducing a basic pH in the pipelines will promote the precipitation of corrosion products.

As a result, those products will create a barrier that will prevent further corrosion of pipelines. Iron carbonate (FeCO3) and iron sulfide (FexS) are corrosion products that when precipitated in the right amount at the right conditions, will be able to protect the pipeline infrastructure. The solubility of the corrosion products is not very well known and it is highly linked to corrosion rate.

The aim of this project is the study of the solubility of the corrosion products for understanding which conditions create a protective layer that will prevent the corrosion of the pipelines.
