    • The present invention relates to the use of a specific group of alkoxylated and/or acylated non-quaternary nitrogen-containing compounds as anti-agglomerants for gas hydrates. The anti-agglomerants are surface-active non-quaternary nitrogen-containing compounds with 1-5 nitrogen atoms, which compounds have at least one hydrophobic group with 6-24 carbon atoms, and where the hydrophobic group is connected to the remainder of the molecule by an amine moiety, an ether moiety or an amide moiety, provided that when the hydrophobic group is connected by means of 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 —CH2CH2O— groups and/or 1-6 hydroxyalkyl groups with 3-4 carbon atoms; and which compounds have at least one C2-C3 acyl group and/or at least one hydroxyalkyl group with 3-4 carbon atoms; 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.
    • 本发明涉及一组特定的烷氧基化和/或酰化非季氮含量化合物作为气体水合物的抗附聚物。 抗附聚物是具有1-5个氮原子的表面活性的非季氮含氮化合物,该化合物具有至少一个具有6-24个碳原子的疏水基团,并且其中疏水基团与分子的其余部分连接 通过胺部分,醚部分或酰胺部分,条件是当疏水基团通过酰胺部分连接到分子的其余部分时,化合物必须含有总共至少两个氮原子,并且任选地含有 1-12个-CH2CH2O-基团和/或1-6个具有3-4个碳原子的羟烷基; 哪些化合物具有至少一个C2-C3酰基和/或至少一个具有3-4个碳原子的羟烷基; 或其盐。 本发明还涉及一种用于抑制导管中气体水合物凝聚的方法,以及包含气体水合物抗凝聚剂,腐蚀抑制剂和/或石蜡沉积抑制剂的组合物。
