1-25. (canceled)
A combination comprising an elongate receptacle containing a drag reducing polymer, wherein the receptacle defines an internal volume which contains said polymer, wherein said internal volume is in the range 10000 cm3 to 150000 cm3.
A combination according to claim 1,
- wherein said receptacle is not self-supporting;
- wherein said receptacle comprises a plastic film material which has a thickness of at least 20 μm and a thickness of less than 2000 μm;
- wherein said receptacle includes a first end and a second end which are spaced apart along the elongate extent of the receptacle, wherein said first end is a closed end;
- wherein the diameter of the internal volume of the receptacle is in the range 5 cm to 15 cm across its entire extent;
- wherein the internal volume of the receptacle is in the range 20000 cm3 to 60000 cm3;
- and said length of the receptacle is in the range 3 m to 15 m;
- wherein the aspect ratio of the receptacle is defined as the length of the internal volume of the receptacle divided by the diameter of the internal volume of the receptacle, wherein said aspect ratio is at least 10 and said aspect ratio is less than 600;
- wherein the weight of drag reducing polymer in said receptacle is at least 15 kg;
- and the total weight is less than 85 kg;
- wherein said drag reducing polymer is selected form the group comprising poly(alpha-olefin), polychloroprene, vinyl acetate polymers and copolymers, poly(alkylene oxide) (PAO) and mixtures thereof;
- and
- wherein the sum of the wt % of said elongate receptacle and said drag reducing polymer in said combination is at least 90 wt %.
