Abstract

See full text

A method of cleaning a pipeline is performed by introducing a treatment composition comprising a colloidal particle dispersion having inorganic nanoparticles with an average particle size of from 500 nm or less into an interior of a pipeline to be cleaned. A pig or body is passed through the pipeline to spread the composition upon surfaces of the interior of the pipeline. The composition and materials adhering to the surfaces of the interior of the pipeline are removed to facilitate cleaning of the pipeline.
