Abstract

Water/oil emulsions are formed in oil wells due to the presence of natural surfactants. As water/oil phase separation is necessary before oil refining, demulsifiers are used to break water/oil emulsions. In this work, environmentally friendly ionic surface-active choline carboxylates were synthesized from anionic exchange involving choline chloride under microwave dielectric heating. Microwave irradiation was also employed as a fast method for following the kinetics of the demulsification process with the synthesized demulsifiers. Choline palmitate showed the best performance as demulsifier.

Kurzfassung

Wasser/Öl-Emulsionen werden in Ölquellen aufgrund anwesender natürlicher Tenside gebildet. Da vor der Mineralölverarbeitung eine Phasentrennung von Wasser und Rohöl erforderlich ist, werden die Wasser/Öl-Emulsionen mit sog. Spaltern gebrochen. In dieser Arbeit wurden umweltfreundliche ionische oberflächenaktive Cholincarboxylate aus anionischem Austausch von Cholinchlorid bei dielektrischer Erwärmung mittels Mikrowellen synthetisiert. Die Mikrowellenbestrahlung wurde auch als schnelles Verfahren zur Verfolgung der Kinetik des Demulgierprozesses mit den synthetisierten Demulgatoren eingesetzt. Cholinpalmitat zeigte die beste Leistung als Demulgator.

Key words: choline carboxylate; demulsifier; demulsification process; crude oil; emulsion; microwave irridation
