Abstract

Foreliggende oppfinnelse angår anvendelse av en spesifikk gruppe med alkoksylerte og/eller acylerte ikke-kvaternære nitrogenholdige forbindelser som anti-agglomererende midler for gasshydrater. De anti-agglomererende midler er overflateaktive, ikke-kvaternære, nitrogenholdige forbindelser med 1-5 nitrogenatomer, disse forbindelsene har minst én hydrofob gruppe med 6-24 karbonatomer og hvor den hydrofobe gruppe er forbundet med resten av molekylet ved en amingruppe, en etergruppe eller en amidgruppe, forutsatt at når den hydrofobe gruppe er forbundet ved hjelp av en amidgruppe til resten av molekylet, må forbindelsene inneholde totalt minst to nitrogenatomer og eventuelt inneholder 1-12 -CH2CH2O- grupper og/eller 1-6 hydroksyalkylgrupper med 3-4 karbonatomer; og forbindelsene har minst én C2-C3 acylgruppe og/eller minst én hydroksyalkylgruppe med 3-4 karbonatomer; eller et salt derav. Oppfinnelsen angår også en fremgangsmåte for å hemme agglomereringen av gasshydrater i en ledning og sammensetninger omfattende gasshydrat anti-agglomererende middel, en korrosjonsinhibitor og/eller en parafinavsetningsinhibitor.
