Method for inhibiting the plugging of conduits by gas hydrates

摘要

The plugging of conduits containing a mixture of low-boiling hydrocarbons and water in inhibited by adding to the mixture an effective amount of at least one alkylated compound of the general formula formula <IMAGE> wherein R1 and R2 each are independently chosen from normal or branched alkyls containing a chain of at least 4 carbon atoms, R5 is an organic moiety containing a chain of at least 4 atoms, X is S, N-R4 or P-R4, R4 is H or an organic substituent, suitably an alkyl or alkenyl group having from 8 to 20 carbon atoms, and Y- is an anion.
