Transportation of wet, CO{sub 2}-containing gases in pipelines requires special measures to prevent corrosion of the pipe wall. A relatively new option uses injection of glycol, the presence of which in the water phase mitigates corrosion. A method has been developed for calculating the phase behavior of glycol in such wet CO{sub 2} pipelines. Composition of the glycol-water condensate in the pipeline is one essential in determination of the corrosion rate. The effect of natural-gas condensate on the mass transfer of glycol and water between liquid glycol-water at the bottom of the pipeline and the gas phase is approached by means of two dispersion criteria. The composition of glycol-water is shown for the various cases considered for the various cases considered for the operation of the 66-km, 36-in. trunklines between the Troll platform of the Norwegian coast and the offshore processing plant on the Troll natural-gas pipeline system.
