Nanoparticles for use with drag reducer additives and method of use

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.

Claims

1. A method of removing drag reducer additive molecules from a pipeline stream, the method comprising: attaching one or more nanoparticles to each drag reducer additive molecule during manufacture of the drag reducer additive molecules; and using the nanoparticle to either destroy the drag reducer additive molecule or to remove the drag reducer additive molecule from the pipeline stream.

2. The method of claim 1 where attaching the nanoparticles to the drag reducer additive molecules comprises adsorption, chemical bonding, electrostatic adhesion, magnetic attraction, dusting, or ionic attraction.

3. The method of claim 1 where using the nanoparticles comprises activating the nanoparticles.

4. The method of claim 3 where activating the nanoparticles causes the nanoparticles to reduce the size of the drag reducer additive molecules.

5. The method of claim 3 where activating the nanoparticles causes the nanoparticles to cause the drag reducer additive molecules to agglomerate.

6. The method of claim 3 where activating the nanoparticles is accomplished through heat, light, magnetic fields, frequencies, vibration, filtering, or chemicals.

7. The method of claim 1 where attaching the nanoparticles to the drag reducer additive molecules occurs immediately prior to using the nanoparticle to either destroy the drag reducer additive molecule or to remove the drag reducer additive molecule from the pipeline stream.

Description

DETAILED DESCRIPTION OF THE INVENTION

(1) The devices and methods discussed herein are merely illustrative of specific manners in which to make and use this invention and are not to be interpreted as limiting in scope.

(2) While the devices and methods have been described with a certain degree of particularity, it is to be noted that many modifications may be made in the details of the construction and the arrangement of the devices and components without departing from the spirit and scope of this disclosure. It is understood that the devices and methods are not limited to the embodiments set forth herein for purposes of exemplification.

(3) In general, in a first aspect, the invention relates to nanoparticles used with long chain poly-alpha-olefins, commercially known as drag reducer additives (DRA). The nanoparticles may be embedded in the original DRA formulation. Additionally or alternately, nanoparticles may be added at some point in the pipeline application. The nanoparticles may be used to destroy the DRA polymer by cleaving or interrupting or restructuring or otherwise breaking its bonds. Alternately, the nanoparticles may be used to agglomerate or coagulate the DRA polymer so that it can be removed mechanically or chemically.

(4) The nanoparticles may be engineered or naturally occurring. The nanoparticles may be embedded or infused in the formulation of the DRA molecule during or after manufacturing by simple addition, absorption, chemical bonding, electrostatic adhesion, magnetic attraction, dusting, ionic attraction, or any other method of mating the nanoparticle to the DRA polymer or using the nanoparticles to primarily or secondarily form the long chain polymer. The nanoparticles may have characteristics that are detectable and may be changed by influencing elements such as heat, light, magnetic fields, changing frequencies, vibration, filtering, chemicals, some physically induced process, or by other nanoparticles. The nanoparticles may be initially inert, allowing the DRA to do its job. When altered, the nanoparticle may be capable of altering the DRA molecule, rendering it benign in size.

(5) The nanoparticle may be activated by a frequency modulated conditioning that triggers an altered state of the nanoparticle, which would in turn rearrange the DRA molecule. Alternately, the nanoparticle may be activated by a magnetically induced energy field that would affect the same changes or by the addition of another nanoparticle. In all cases, the re-arranged molecule may not have to be removed from the stream, but rather would have a more acceptable molecular weight for motor fuel combustion.

(6) Alternately, the nanoparticles may alter the DRA molecule such that the DRA may be removed physically, such as through filtering, centrifuging, absorbing, or flocculating.

(7) Whereas, the devices and methods have been described in relation to the drawings and claims, it should be understood that other and further modifications, apart from those shown or suggested herein, may be made within the spirit and scope of this invention.
