Abstract

Skumbegrensende blanding omfattende et organosiloksan i et flytende, organisk fortynningsmiddel. Den Skumbegrensende blanding inneholder minst 0,1 vekt-% av organosiloksanet og organosiloksanet har en vekt- gjennomsnittlig molekylvekt på minst 1.800.000 og en polydispergerbarhet på ikke mer enn 4. Disse blandinger er spesielt nyttige for å begrense dannelse av skum under separasjon av gass fra en blanding av råolje og gass.
