Test protocol guides selection of wet-gas corrosion inhibitor

06/12/2006
A proper corrosion-inhibition test protocol helps ensure the success of increasingly expensive offshore oil and gas projects.Several offshore wet-gas pipelines worldwide carry high concentrations of acid gas across long distances under hydrate-forming conditions. Some of these pipelines use glycol for hydrate control. Under certain conditions, severe corrosion can occur in these pipelines without corrosion inhibitors.A laboratory protocol that recreated system conditions developed corrosion inhibitors suitable for wet-gas systems with glycol.Modeling and knowledge of the specific operating facility then allowed assessment of inhibitor effectiveness under system conditions.With effective c...
