Abstract:
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 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.
