Kemelix D501
Kemelix D501 is a concentrated polymeric alkoxylate. Kemelix D501 works as a superior demulsifier intermediate, destabilising water-in-oil emulsions to facilitate the rapid separation of water from crude oil. This product also benefifts from non-emulsifier properties indicating its ability to prevent emulsion formation. Kemelix D501 is highly effective at low inclusion levels meaning reduction in costs of demulsifier formulations. It also has a high speed of action, increasing it's suitability in separation vessels with shorter residence times. Croda's reccomended crude oil demulsifier formulation for Kemelix D501 is 10-1000ppm.
Resin alkoxylates and polyimine derivatives should be individually evaluated and then the best performing of these products should be combined. Optimised performance can then be achieved by adding our modified polyols or other products from the Kemelix range. Solubility details of Kemelix D501 can be found in the demulsifer function guide in the Demulsifiers brochure.
