| Summary: | Pipelines transporting oil and gas are vulnerable to internal corrosion when
water forms a part of the transported fluids. The presence of carbon dioxide
(CO2) in the fluid accelerates the corrosion rate due to its reaction with water
which results in forming carbonic acid, and hence, water pH is reduced. The
corrosion rate prediction is an important task needed to manage and control the
corrosion. The prediction can be carried on by selecting one of many empirical
and mechanistic models that developed for corrosion rate prediction. One of
these models is NORSOK model, an empirical model developed by NORSOK
Norwegian standard for CO2 corrosion prediction in straight pipes. In this paper
NORSOK model has been coupled to thermal and hydraulic models to predict
CO2 corrosion rate along pipelines. |
