Solvent free oil soluble drag reducing polymer suspension
Smith Kenneth W,Haynes Leo,Massouda Debora Flanagan +2 more
- 27 May 1994
TL;DR: In this paper, a hydrocarbon soluble drag reducing suspension is described as well as a process for obtaining the same, which is directed toward producing a drag reducing product which is easily transportable, nonhazardous, easily handled and while providing a significant increase in drag reduction capability over existing commercial products.

Slurry drag reducer
Aysen Dindi,Ray L. Johnston,Yung N. Lee,Massouda Debora Flanagan +3 more
- 02 Sep 1994
TL;DR: In this paper, the flow of a stream comprised of hydrocarbons is improved by introducing into the stream a stable, nonagglomerating suspension comprising: (a) water, (b) highly dispersed in the water, and substantially insoluble therein, and extremely finely-divided, non-crystalline, ultra-high molecular weight, hydrocarbon-soluble, undegraded polyalkene having 2 to about 30 carbon atoms per alkene precursor and an inherent viscosity of at least 20 dL/g, and a small but effective amount

Continuous neat polymerization and ambient grinding methods of polyolefin drag reducing agents
Jeffery R. Harris,John F. Motier,Callaway Michael,George G. Ramsay +3 more
- 03 Nov 2003
TL;DR: In this article, a process for continuously producing a polymer drag reducing agent (DRA) is described, which concerns mixing a monomer and a catalyst in at least one continuously stirred tank reactor (CSTR) to form a mixture.

Methods for forming amorphous ultra-high molecular weight polyolefins for use as drag reducing agents
Eaton Gerald B,Michael J. Monahan,Alan K. Ebert,Tipton Robert J,Eduardo Baralt +4 more
- 15 Jan 2002
TL;DR: In this paper, the authors proposed improved drag reducing agents and methods of forming improved drag reduction agents comprising the steps of isomerizing olefin monomers to form isomerized olelin monomers, polymerizing the isomerised olein monomers in the presence of at least one catalyst to form a polyolefin drag reducing agent having unexpectedly superior drag reduction properties when combined with liquid hydrocarbons, such as viscous crude oil.

Drag reducing agent slurries having alfol alcohols and processes for forming drag reducing agent slurries having alfol alcohols
Eaton Gerald B,Alan K. Ebert +1 more
- 08 Jun 2001
TL;DR: In this paper, a polyalphaolefin and at least one alfol alcohol are combined with a catalyst in a reactant mixture to form a drag reducing agent slurry, and a process for reducing drag in a conduit is described.
