ABSTRACT:
The process for slowing the growth and/or agglomeration of hydrates in a fluid comprising water and gases comprises adding gas hydrate growth and/or agglomeration inhibitors comprising an essentially water soluble polymer, characterized by a total number of rotational degrees of freedom per statistical repeat unit RDFTm of over 9, preferably over 10, and a degree of polymerization DP of a statistical repeat unit in the range 18/RDFTm to 200,000, preferably in the range 20/RDFTm to 100,000. The growth and/or agglomeration inhibitor(s) is/are generally incorporated into the fluid to be treated in a concentration of 0.05% to 5% by weight with respect to the amount of water in the medium.
