New Developments in the Use of Chemicals for Pipeline Corrosion Control

Advances are continually being made in the corrosion management of pipelines, in particular gas production pipelines. Flow simulation models can be developed which allow for changing conditions at particular areas of a pipeline. Corrosion rate trends can be correlated with these simultaneously changing process conditions. It is shown how water hold-up, and its consequent effects, can be overcome by chemical means. Recent developments in corrosion monitoring and inspection techniques that have led to improvements in the way pipelines can be monitored for corrosion are assessed. New developments are also described in the way corrosion inhibitors are evaluated for their environmental acceptability. [This is an unrefereed preprint].
