Abstract:
Sediment material from corrosion (containing magnetic iron (oxide based)) has been found accumulating in pumps, valves, on pigs and in line inspection tools.
Some of the key players in corrosion are oxygen (O2), carbon dioxide (CO2) and hydrogen sulfide (H2S). These can cause corrosion when present in the low ppm to ppb range. A robust, reliable method to detect trace levels of dissolved corrosion gases (O2, H2S and CO2) in pipeline products does not exist. A method was developed that uses a liquid phase injection, a backflush so the fixed gas column does not get contaminated, and a sensitive detector. Low ppm detection limits were achieved.
