The paper discusses black powder formation in the corrosion experiments with field TEG and lab mixed TEG. TEG samples were collected at the gas receiving facilities and in the TEG dehydration units that delivered gas to a pipeline network. The objective was to determine the corrosion rates and production rate of solids, to better understand the rate controlling mechanisms and to find means to reduce the black powder problem. The experiments were run at 5, 25 and 40 °C, with the test gas consisting of 100 kPa CO2 and 40 Pa H2S and the salt content of 100 to 10000 ppm. The test duration varied from 60 to 102 days. Corrosion rates were determined from weight loss measurements and varied in the range 1-30 ?m/year. The experiments showed that the corrosion rate increased significantly when solid iron sulfide accumulated on the steel surface and the liquid contained high amounts of dissolved salt.

Key words: Black powder, Corrosion, TEG, CO2, H2S
