ABSTRACT:
Discussed is a process for preventing clathrate hydrate masses from detrimentally impeding the possible flow of a fluid susceptible to clathrate hydrate formation. The process is particularly useful in the natural gas and petroleum production, transportation and processing industry where gas hydrate formation can cause serious problems. Additives preferably contain one or more five member, six member and/or seven member cyclic chemical groupings. Additives include polymers having lactam rings. Additives can also contain polyelectrolytes that are believed to improve conformance of polymer additives through steric hinderance and/or charge repulsion. Additional additives include alkoxy compounds, and particularly those comprising ethoxy and or propoxy polymer blocks. Further additives include alcohols and oxazoline polymers which are preferably used in combination with polymers having lactam rings. Additives are useful in controlling clathrate hydrates in highly saline aqueous liquids.
