N2 - An amine based C02 corrosion inhibitors and an imidazoline based C02 corrosion inhibitor has beentested in a two-phase laboratory flow loop system under conditions of a mature gas condensate well inAustria.After a detailed description of the experimental setups, degradation rates of material API (1) L-80 (UNSG41300) as function of flow velocity and inhibitor dosage are presented. Further one the influence ofchloride addition on inhibitor performance has been investigated. All results are discussed with respectto critical inhibitor concentration to reach nearly 100 % inhibitor efficiency.Inhibitor one exhibits as an active ingredient alkylamine dissolved in ethylene glycol and differentalcohols and the effect of inhibitor two is basically based on imidazoline dissolved in different alcohols.Results demonstrate that the test rig delivers resonable results with respect to inhibitor protection rates.Independent of superficial flow velocities (tested between 3 and 35 m/s) both inhibitors exhibit a goodperformance, as long as dosed above their critical concentration. The critical concentration is clearlybelow 100 ppm to the liquid phase. Addition of chlorides affects the performance of the alkylaminebased inhibitor significantly more than in case of the imidazoline.
