Abstract
A method for inhibiting corrosion in pipelines for transporting oil and gas is described. A nano-machine is fed along with an inert gas to the pipeline to deliver a corrosion inhibitor which is chemically bonded to the nano-machine. The nano-machine is made by attaching a corrosion inhibitor to a nanoparticle by way of a covalent bond. When the nano-machine encounters a source of corrosion in the pipeline, the corrosion inhibitor is released to treat the corrosion.
