摘要:
A method of inhibiting hydrates in a fluid comprising water and gas comprising adding to the fluid an effective hydrate-inhibiting amount of a composition comprising one or more homo- or co-polymers of N-alkyl(alkyl)acrylamide synthesized by polymerizing one or more N-alkyl(alkyl)acrylamide monomers in a solvent comprising a glycol ether of formula CH3—(CH2)m—(O—CH2—CH2)n—OH where m is an integer of 0-1, and n is an integer ≥1.
摘要:
Disclosed and claimed is a composition and method of inhibiting the formation of hydrate agglomerates in a fluid comprising water, gas, and optionally liquid hydrocarbon. The composition comprises the following formula and the method comprises adding to the fluid an effective anti-agglomerant amount of any of the following formula and optionally salts thereof. R1, R2, and R3 are each independently CnH2n+1 or benzyl. R4 is C4-C20 alkyl or alkenyl. n is an integer from 0 to 10. X− is a counterion.

A method of inhibiting hydrates in a fluid comprising water and gas comprising adding to the fluid an effective hydrate-inhibiting amount of a composition comprising one or more co-polymers of N-alkyl(alkyl)acrylamide monomers and one or more cationic monomers selected from acid and alkyl chloride quaternary salts of N,N-dialkylaminoalkyl(meth)acrylates and N,N-dialkylaminoalkyl(meth)acrylamides.

摘要:
A method for thread laying and a thread laying machine; thread laying has been achieved by a machine that has a vacuum table and above it a gantry with a thread dispensing device on a shuttle operating in an x- and y- direction; the gantry may be fixed to a pair of carriage on the x-axis driven in unison or each of the carriages may be independently driven; curved threads as well as threads on a mold may be laid down on a substrate; typical material produced is sail material of considerable thread pattern complexity; single threads or a multiple of threads may be laid down through one thread head with an adhesive properly coating the threads; multiple thread heads as well associated apparatus such as laser cutters and the like are mounted on the gantry.
