| titleOfInvention | Additive for preserving fluidity of fluids containing gaseous hydrates |
| abstract | FIELD: chemistry. n SUBSTANCE: anti-agglomerates are surface-active non-quaternary nitrogen-containing compounds with 1-5 nitrogen atoms, which have at least one hydrophobic group with 6-24 carbon atoms, and where the hydrophobic group is bonded to the remainder of the molecule by an amine moiety, an ether moiety or an amide moiety, provided that when the hydrophobic group is bonded by an amide moiety to the remainder of the molecule, the compounds must contain a total of at least two nitrogen atoms, and optionally contain 1-12 -CH 2 CH 2 O- groups and/or 1-6 hydroxyalkyl groups with 3-4 carbon atoms; and compounds having at least one C 2 -C 3 acyl group and/or at least one hydroxyalkyl group with 3-4 carbon atoms; or a salt thereof. The method of inhibiting agglomeration of gaseous hydrates in a conduit, containing a fluid mixture which contains hydrocarbons with 1-4 carbon atoms and water, involves adding to the mixture said agglomerate in amount of 0.05-10% of the content of water in the fluid mixture. The composition contains said anti-agglomerate of gaseous hydrates, a corrosion inhibitor and/or a paraffin deposition inhibitor. n EFFECT: high efficiency of the anti-agglomerate for gaseous hydrates and biodegradability thereof. n 9 cl, 2 ex, 2 tbl |
