摘要

A new erosion corrosion testing facility has been setup in cooperation with an Austrian oil and gas producing company. The test rig consists of a gas flow loop with fluid addition. The two distinctive features of this test rig are that the gas - liquid two phase is accelerated up to 35 m/s at 15 bars and a continuous, infinite inhibitor dosing is possible. Tube diameters between 10 and 20 mm can be investigated at different flow regimes. Gas is pumped in a loop by a Diaphragm-Compressor and liquids are only used once and are separated downstream of the specimens. Tube specimens are evaluated by gravimetry and 3D optical device to determine average depth of and deepest point of attack. After a detailed description of the experimental setup, experimental limits are described with respect to maximum and minimum flow rates of gas and fluid. Degradation rates are presented for material L 80 as function of testing time, flow velocity (tube diameter), tube position in test rig and inhibitor concentration. The long term goal is to determine limiting flow velocities for different inhibitors and to describe inhibitor performance as function of flow velocity. Results of two different inhibitors are presented.
