METHODS OF DESIGNING GREEN DEMULSIFIERS

Green demulsifiers useful for demulsifying emulsions of water and crude oil are made by reacting together an alcohol, a multifunctional acid and/or anhydride, and a fatty acid, and optionally a polyol that is polyethylene glycol and/or polypropylene glycol. The green demulsifier has ester bonds betw...

Beschreibung
Zusammenfassung:	Green demulsifiers useful for demulsifying emulsions of water and crude oil are made by reacting together an alcohol, a multifunctional acid and/or anhydride, and a fatty acid, and optionally a polyol that is polyethylene glycol and/or polypropylene glycol. The green demulsifier has ester bonds between the reactant moieties. These ester bonds can hydrolyze which results in relatively high biodegradation. Des désémulsifiants verts utiles pour désémulsionner des émulsions d'eau et de pétrole brut sont obtenus par réaction d'un alcool, d'un acide multifonctionnel et/ou d'un anhydride, et d'un acide gras, et éventuellement d'un polyol qui est du polyéthylène glycol et/ou du polypropylène glycol. Le désémulsifiant vert comporte des liaisons ester entre les fractions réactives. Ces liaisons ester peuvent s'hydrolyser, ce qui entraîne une biodégradation relativement élevée.
