Patent number: 7939584Abstract: Drag reduction of hydrocarbon fluids flowing through pipelines of various lengths is improved by polyolefin drag reducer dispersions or dispersions using bi- or multi-modal particle size distributions. Drag reducers having larger particle sizes dissolve more slowly than drag reducers having smaller particle sizes. By using at least bi-modal particle size distributions drag reduction can be distributed more uniformly over the length of the pipeline where smaller sized particles dissolve sooner or earlier in the pipeline and larger sized particles dissolve later or further along the pipeline.Type: GrantFiled: June 13, 2006Date of Patent: May 10, 2011Assignee: Baker Hughes IncorporatedInventors: Jeffery R.

Patent number: 7119132Abstract: A process for continuously producing a polymer drag reducing agent (DRA) is described. The process concerns mixing a monomer and a catalyst in at least one continuously stirred tank reactor (CSTR) to form a mixture. The mixture is continuously injected into a volume continuously formed by a thermoplastic material, such as polyethylene. The thermoplastic material is periodically sealed off to form a temporary container or bag. The monomer is permitted to polymerize in the temporary container to form polymer. In one non-limiting embodiment, the polymerization in the bag takes place within an inert, circulating fluid that accelerates heat transfer. The polymer and the temporary container are then ground together, preferably at non-cryogenic temperatures, to produce a particulate polymer drag reducing agent. In one preferred, non-limiting embodiment, the grinding or pulverizing occurs in the presence of at least one solid organic grinding aid.Type: GrantFiled: October 27, 2003Date of Patent: October 10, 2006Assignee: Baker Hughes IncorporatedInventors: Jeffery R.

Patent number: 6946500Abstract: A process for producing fine particulate polymer drag reducing agent (DRA) without cryogenic temperatures, is described. The grinding or pulverizing of polymer, such as poly(alpha-olefin) may be achieved by the use of at least one solid organic grinding aid and at least one liquid grinding aid. In one non-limiting embodiment of the invention, the grinding is conducted at ambient temperature. Examples of a solid organic grinding aid include ethene/butene copolymer particles, paraffin waxes and solid alcohols. An example of a suitable liquid grinding aid includes a blend of glycol, water and isopropyl alcohol. Particulate DRA may be produced at a size of about 500 microns or less. Use of an attrition mill is preferred.Type: GrantFiled: December 17, 2002Date of Patent: September 20, 2005Assignee: Baker Hughes IncorporatedInventors: Jeffery R. Harris, John F. Motier

Publication number: 20040167300Abstract: Temperature control and efficient heat transfer are important to producing high quality polymer drag reducing agents from alpha-olefin and/or other monomers. Many polymerization reactions are exothermic, and controlling or minimizing the exotherm combined with low reaction temperatures yields high molecular weight and, for poly(alpha-olefins), high quality drag reducing agent polymers. It has been found that a shell and tube heat exchanger-type reactor, with the inner tubes hosting the reaction mixture and a coolant circulating through the shell side gives good temperature control. The use of appropriate release agents helps to keep the inner reaction chambers from building up any polymer residue. These reactors can be operated in a continuous filling and harvesting mode to facilitate the continuous production of polymer drag reducing agent and related formulations.Type: ApplicationFiled: February 24, 2004Publication date: August 26, 2004Inventors: Nagesh S.
