trends, including the presence of paraffins or oxygen in gas streams
ple where the Clinton site formulated
a fit-for-purpose corrosion inhibitor
that could tackle not only common
corrosive agents like carbon dioxide
and hydrogen sulfide, but also oxygen,
relatively uncommon and difficult
to treat in large quantities. " Oxygen
poses a very high corrosion risk when
present inside pipelines or surface
production equipment. This particular
customer had oxygen in their transmission
lines without the ability to remove
or block the oxygen contamination, "
explains Wilson. The challenge
was exacerbated since the amount of
oxygen was too high for a traditional
scavenger product, so an inhibitor
to block the interaction of oxygen at
the metal surface was the best option.
The final inhibitor formulation included
known corrosion inhibitors to
target CO2 and H2S, as well as other
additives to inhibit and passivate the
abundant oxygen.
H2S is another troublesome species
- not only is it corrosive, but it
FIGURE 3. Specialized injection equipment helps to
ensure the longterm integrity of polymers used for
enhanced oil recovery
is also highly flammable and toxic.
A common method for treating H2S
is to use triazine scavengers, but triazine
can introduce serious production
issues. For instance, the high
pH of triazine can cause the precipitation
of calcium carbonate scale,
and once the triazine is spent, it can
