  • Patent number: 11732181
    Abstract: A method of treating an apparatus to remove surface deposits therefrom is performed by selecting a colloidal particle dispersion having inorganic nanoparticles with an average particle size of from 500 nm or less that exhibit properties of Brownian motion that facilitate penetration of solid deposits on surfaces of an apparatus that is subject to surface deposits from contact with fluids. The surfaces of the apparatus are contacted with a treatment composition comprising the colloidal particle dispersion. The composition is allowed to act upon the materials adhering to the surfaces of the apparatus to loosen and breakup the materials adhering to the surfaces of the apparatus. The loosened and broken materials are removed from the surfaces of the apparatus.

  • Patent number: 11512241
    Abstract: A method of treating a pipeline is performed by selecting a colloidal particle dispersion having inorganic nanoparticles with an average particle size of from 500 nm or less that exhibit properties of Brownian motion that facilitate penetration of solid deposits on interior surfaces of a pipeline. A treatment composition comprising the colloidal particle dispersion is introduced into an interior of a pipeline by at least one of (A) introducing a batch amount of the treatment composition in a selected volume into the interior of the pipeline, and (B) continuously introducing the treatment composition at a selected rate into the interior of the interior of the pipeline. The composition is allowed to act upon the surfaces and materials adhering to the surfaces of the interior of the pipeline.

  • Patent number: 11077474
    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.
