Abstract
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.
Claims20
A method of cleaning a pipeline comprising:
- selecting a colloidal particle dispersion having inorganic nanoparticles with an average particle size of 500 nm or less that exhibit properties of Brownian motion that facilitate penetration of solid deposits on interior surfaces of a pipeline;
- introducing a treatment composition comprising the colloidal particle dispersion and a drying agent into an interior of a pipeline;
- allowing the composition to act upon materials adhering to the surfaces of the interior of the pipeline to loosen and break up the materials adhering to the surfaces of the interior of the pipeline;
- and
- removing the loosened and broken materials from the pipeline.
A method of cleaning the gas or liquid petroleum pipeline comprising:
- selecting a colloidal particle dispersion having inorganic nanoparticles with an average particle size of 500 nm or less that exhibit properties of Brownian motion that facilitate penetration of solid deposits on interior surfaces of a pipeline;
- introducing a treatment composition comprising the colloidal particle dispersion into an interior of a pipeline having a diameter of 24 inches or more;
- allowing the composition to act upon materials adhering to the surfaces of the interior of the pipeline to loosen and break up the materials adhering to the surfaces of the interior of the pipeline;
- and
- removing the loosened and broken materials from the pipeline.
