CORROSION EXPERIENCES AND INHIBITION PRACTICES MANAGINGWET SOUR SALTY GAS PIPELINE ENVIRONMENTS CONTAMINATED WITHELEMENTAL SULFUR DEPOSITS

摘要

Corrosion experiences and inhibition practices operating wet sour gas gathering systemsrnare discussed with emphasis on wet salty pipelines contaminated with elemental sulfurrndeposition. Baseline pitting corrosion rates and inhibitor performance in a series of sulfurrnspiked laboratory test protocols are also reviewed. Tests were conducted simulating fieldrnenvironments in Western Canada, challenging corrosion inhibitors to protect pipeline assetsrnfrom severe pitting corrosion consequences, when sour produced brine is contaminated withrnelemental sulfur compounds.
