Abstract
A drag reducing composition includes a drag reducing polymer; a magnetic particle incorporated in the drag reducing polymer; and a suspension fluid medium. In some compositions, the magnetic particle comprises a fatty acid and/or at least one of a magnetic metal, a magnetic metal alloy, or a metal oxide core. A method of forming a drag reducing composition includes reacting alpha-olefin monomers in the presence of a polymerization catalyst and a magnetic particle to produce a drag reducing polymer incorporated with the magnetic particle.

A drag reducing composition, comprising:
- a drag reducing polymer;
- a magnetic particle incorporated in the drag reducing polymer;
- and
- a suspension fluid medium.
A method of forming a drag reducing composition, comprising:
- providing alpha-olefin monomers with a carbon chain length of between two and twenty carbon atoms;
- providing a polymerization catalyst;
- providing a magnetic particle in an amount from 1% to 5% by total volume;
- and
- reacting the alpha-olefin monomers in the presence of the polymerization catalyst to produce a drag reducing polymer incorporated with the magnetic particle.
A method, comprising:
- supplying a drag reducing composition into a hydrocarbon stream flowing in a conduit, the drag reducing composition comprising a drag reducing polymer and a magnetic nanoparticle and present in an amount sufficient to reduce a drag of the hydrocarbon stream;
- applying a magnetic force to the hydrocarbon stream;
- and
- removing at least a portion of the drag reducing polymers using the magnetic force.
