Abstract
A drag reducing composition comprises a sealed temporary container; and a drag reducing agent and up to 20 weight percent of a dispersing fluid disposed in the sealed temporary container. The drag reducing agent comprises polyolefin particles having a particle size of about 10 to about 2,000 microns; and the dispersing fluid comprising water, an alcohol, a hydrocarbon, or a combination comprising at least one of the foregoing.
Claims22
A drag reducing composition comprising:
- a sealed temporary container;
- and
- a drag reducing agent and up to 20 weight percent of a dispersing fluid disposed in the sealed temporary container;
- wherein the drag reducing agent comprises polyolefin particles having a particle size of about 10 to about 2,000 microns;
- the dispersing fluid comprises water, an alcohol, a hydrocarbon, or a combination comprising at least one of the foregoing;
- the temporary container comprises a container material, which includes a polyethylene, a polypropylene, an ethylene propylene copolymer, a polystyrene, a polylactic acid, a polyamide, a polyester, a polystyrene, an ethylene vinyl acetate copolymer, an ethylene vinyl alcohol copolymer, a polyvinylpyrrolidone, an ethylene vinylpyrrolidone copolymer, a vinylpyrrolidone vinyl acetate copolymer, a polyvinyl acetate, a polyvinyl alcohol, a polyethylene oxide, a polyethylene glycol, polyvinylidene chloride, a polysaccharide or its derivative, or a combination comprising at least one of the foregoing;
- and
- the weight percent is based on the total weight of the drag reducing composition, and
- wherein the temporary container has a thickness of about 1 to about 1,000 microns.
A drag reducing composition comprising:
- a sealed temporary container;
- and
- a drag reducing agent and up to 20 weight percent of a dispersing fluid disposed in the sealed temporary container;
- wherein the drag reducing agent comprises polyolefin particles having a particle size of about 10 to about 2,000 microns;
- the dispersing fluid comprises water, an alcohol, a hydrocarbon, or a combination comprising at least one of the foregoing;
- the temporary container comprises a container material, which includes a polyethylene, a polypropylene, an ethylene propylene copolymer, a polystyrene, a polylactic acid, a polyamide, a polyester, a polystyrene, an ethylene vinyl acetate copolymer, an ethylene vinyl alcohol copolymer, a polyvinylpyrrolidone, an ethylene vinylpyrrolidone copolymer, a vinylpyrrolidone vinyl acetate copolymer, a polyvinyl acetate, a polyvinyl alcohol, a polyethylene oxide, a polyethylene glycol, polyvinylidene chloride, a polysaccharide or its derivative, or a combination comprising at least one of the foregoing;
- and
- the weight percent is based on the total weight of the drag reducing composition, and
- wherein the temporary container has two or more layers, and at least one layer comprises the container material.
A drag reducing composition comprising:
- a sealed temporary container;
- and
- a drag reducing agent and up to 20 weight percent of a dispersing fluid disposed in the sealed temporary container;
- wherein the drag reducing agent comprises polyolefin particles having a particle size of about 10 to about 2,000 microns;
- the dispersing fluid comprises water, an alcohol, a hydrocarbon, or a combination comprising at least one of the foregoing;
- the temporary container comprises a container material, which includes a polyethylene, a polypropylene, an ethylene propylene copolymer, a polystyrene, a polylactic acid, a polyamide, a polyester, a polystyrene, an ethylene vinyl acetate copolymer, an ethylene vinyl alcohol copolymer, a polyvinylpyrrolidone, an ethylene vinylpyrrolidone copolymer, a vinylpyrrolidone vinyl acetate copolymer, a polyvinyl acetate, a polyvinyl alcohol, a polyethylene oxide, a polyethylene glycol, polyvinylidene chloride, a polysaccharide or its derivative, or a combination comprising at least one of the foregoing;
- and
- the weight percent is based on the total weight of the drag reducing composition;
- and
- wherein the temporary container has an inner surface and an opposing outer surface, and a coating is disposed on at least one of the inner and outer surfaces of the temporary container, the coating comprising a wax, a silicone, or a combination comprising at least one of the foregoing.
A drag reducing composition comprising:
- a sealed temporary container;
- a drag reducing agent and up to 20 weight percent of a dispersing fluid disposed in the sealed temporary container;
- and
- a sealed pouch disposed inside the sealed temporary container;
- wherein the drag reducing agent comprises polyolefin particles having a particle size of about 10 to about 2,000 microns;
- the dispersing fluid comprises water, an alcohol, a hydrocarbon, or a combination comprising at least one of the foregoing;
- the temporary container comprises a container material, which includes a polyethylene, a polypropylene, an ethylene propylene copolymer, a polystyrene, a polylactic acid, a polyamide, a polyester, a polystyrene, an ethylene vinyl acetate copolymer, an ethylene vinyl alcohol copolymer, a polyvinylpyrrolidone, an ethylene vinylpyrrolidone copolymer, a vinylpyrrolidone vinyl acetate copolymer, a polyvinyl acetate, a polyvinyl alcohol, a polyethylene oxide, a polyethylene glycol, polyvinylidene chloride, a polysaccharide or its derivative, or a combination comprising at least one of the foregoing;
- and
- the weight percent is based on the total weight of the drag reducing composition.
A drag reducing composition comprising a plurality of connected but individually sealed temporary containers, at least one of the individually sealed temporary container comprising a drag reducing agent and up to 20 weight percent of a dispersing fluid based on the total weight of the individually sealed temporary container,
- wherein the drag reducing agent comprises polyolefin particles having a particle size of about 10 to about 2,000 microns;
- the dispersing fluid comprises water, an alcohol, a hydrocarbon, or a combination comprising at least one of the foregoing;
