Abstract
A method of assembling and/or operating apparatus for undertaking a chemical reaction. The apparatus includes a housing in which a precursor of a receptacle is arranged. A fluid (F1) may be introduced into said precursor to cause the precursor to inflate.
Claims17
An apparatus for carrying out a polymerisation reaction to produce a drag reducing polymer, said apparatus comprising a housing in which a distended receptacle is arranged, wherein said distended receptacle is arranged to receive reagents for reaction in the apparatus, wherein said housing comprises a first elongate tube in which said receptable is positioned, wherein said first elongate tube has an internal surface wherein at least 60% of the area of an external wall area of said receptacle contacts said internal surface;
- and
- wherein said housing comprises a second elongate tube which is coaxial with said first tube and said first tube is positioned within the second tube, said first and second tubes being radially spaced apart so an annular gap is defined between the first and second tubes, wherein said annular gap defines a fluid passage for a coolant fluid.
An apparatus for carrying out a polymerisation reaction to produce a drag reducing polymer, said apparatus comprising a housing in which a distended receptacle is arranged, wherein said distended receptacle is arranged to receive reagents for reaction in the apparatus;
- the apparatus is arranged for delivery of coolant fluid from the container (C1) to a region outside the distended receptacle;
- wherein the apparatus is arranged for delivery of monomer into the distended receptacle;
- wherein said monomer is for preparation of a polymeric drag reducing agent selected from the group comprising poly(alpha-olefin), polychloroprene, vinyl acetate polymers and copolymers, poly(alkylene oxide) (PAO), and mixtures thereof.
