<p>Procedure for the inhibition, growth and/or agglomeration of hydrates in the body of a fluid comprising water and a gas in conditions where hydrates can form comprises the incorporation of a water soluble polymer of general formula (I): ÄAÜnÄBÜmÄCÜp (I); where motifs ÄAÜ contains a sulphonate group, ÄBÜ contains a hydrophilic monomer; ÄCÜ containing a hydrophobic monomer; and n, m and p represent the relative proportions. Preferably the ÄAÜ motifs are derived from compounds chosen from acrylamido-methyl-propane-sulphonate, methacrylamido-methyl-propane-sulphonate, vinyl-sulphonate and styrene-sulphonate; the ÄBÜ motifs are derived from a compound chosen from acrylic acid, methacrylic acid, acrylamide and methacrylamide; and the ÄCÜ motifs are derived from 3 - 14 C alkyl methacrylates such as nonyl methacrylate.</p> |
