Corrosion is a major concern in transmission pipelines that transport captured CO2. While dry CO2 is
noncorrosive, significant corrosion has been reported in dense phase CO2 with trace amounts of water
and impurities such as O2, H2S, SOx, and NOx. The aim of this work is to improve our understanding of
the physicochemical aspects on the corrosion of carbon steels in the high-pressure environments
associated with CO2 transmissions pipelines. The effect of flow on the corrosion of X65 carbon steel was
investigated in a series of autoclave tests with different combinations of impurity concentrations in
supercritical CO2 condition (8 MPa and 35oC). The corrosion rate of samples was determined by weight
loss measurements. The surface morphology and the composition of the corrosion product layers were
analyzed by using surface analytical techniques (SEM and EDS). Localized corrosion was measured via
surface profilometry after corrosion products were removed. Results showed that no corrosion was
observed in the supercritical CO2 with 650 ppm of water, 50 ppm SO2, and 100 ppm NO, but corrosion
occurred when SO2 concentration was increased to 4500 ppm and 40,000 ppm of O2 was added to the
system. The presence of flow significantly accelerated the corrosion of carbon steel. Furthermore,
localized corrosion was observed in the presence of both O2 and flow.
