NITROGEN-CONTAINING ANTI-AGGLOMERANTS FOR PRESERVING THE FLUIDITY OF FLUIDS CONTAINING GAS HYDRATES

The present invention relates to the use of a specific group of acylated nitrogen-containing compounds as anti-agglomerants for gas hydrates. The anti-agglomerants are surface active nitrogen-containing compounds with 1-7 nitrogen atoms, which compounds have at least two hydrophobic groups with 6-24...

Beschreibung
Zusammenfassung:	The present invention relates to the use of a specific group of acylated nitrogen-containing compounds as anti-agglomerants for gas hydrates. The anti-agglomerants are surface active nitrogen-containing compounds with 1-7 nitrogen atoms, which compounds have at least two hydrophobic groups with 6-24 carbon atoms, and where the hydrophobic groups are connected to the remainder of the molecule by an amine moiety or an amide moiety, and which compounds have at least one C2-C5 acyl group; or a salt thereof. The invention also relates to a method for inhibiting the agglomeration of gas hydrates in a conduit, and compositions comprising the gas hydrate anti-agglomerant, a corrosion inhibitor and/or a paraffin deposition inhibitor. La présente invention concerne l'utilisation d'un groupe spécifique de composés à azote acylé comme anti-agglomérants pour hydrates de gaz. Les anti-agglomérants sont des composés azotés tensioactifs contenant 1 à 7 atomes d'azote, ces composés contenant au moins deux groupes hydrophobes contenant 6 à 24 atomes de carbone, et les groupes hydrophobes étant liés au reste de la molécule par un fragment amine ou un fragment amide, et ces composés contiennent au moins un groupe acyle en C2 à C5 ; ou un sel de ceux-ci. L'invention concerne également un procédé d'inhibition de l'agglomération d'hydrates de gaz dans une conduite, et des compositions comprenant l'anti-agglomérant d'hydrates de gaz , un inhibiteur de corrosion et/ou un inhibiteur de dépôt de paraffine.
