Abstract
Nanoparticles may be used in the formulation of long chain poly-alpha-olefins, commercially known as Drag Reducer Additives (“DRA”). These nanoparticles may be embedded in the original DRA formulation and/or added at some point in the pipeline application so they can then be used to destroy the DRA polymer by cleaving, interrupting, or restructuring the DRA or otherwise breaking its bonds or to agglomerate or coagulate the polymer so it can be removed mechanically or chemically.
