Top-of-the-Line (TOL) corrosion is a significant problem associated with the transportation of wet natural gas in the oil and gas industry. It has the potential to cost the industry millions of dollars every year through the replacement of affected pipelines and lost or deferred production. There is increasing research attention given to the development of continuous chemical treatment inhibitors to mitigate TOL corrosion. Different techniques have been developed; however volatile corrosion inhibitors (VCI’s) hold the most promise. It is anticipated that VCI’s may be injected continuously into the produced fluids at the bottom of the line and due to their volatility disperse through the gas phase and ultimately co-condense along with water organic acids and corrosive gases on the internal pipe wall thus providing corrosion inhibition. Generic volatile inhibitor compounds have been tested in a variety of different laboratory tests including the Nalco Cooled Finger Probe the Curtin Horizontal Cooled Tube the CEION cooled Probe and a classical bubble test to verify both Top-of-the-Line and the Bottom-of-the-Line inhibition properties. The laboratory test methods were also compared against each other and against a common field test method (CEION Probe) for TOL corrosion.
