Kemelix 3627X
Kemelix 3627X is a resin alkoxylate designed for use in all demulsifier formulations. It acts as a dropper to coalesce water droplets and release free water. The class leading speed of action of Kemelix 3627X makes it a clear first choice ingredient for all demulsifier formulations, including those with separation vessels with low residence times. Kemelix 3627X performs exceptionally well as a demulsifier for heavy crude oil. Croda's reccomended crude oil demulsifier formulation for Kemilix 3627X in heavy oil 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 3672X can be found in the demulsifer function guide in the Demulsifiers brochure.
First Choice Demulsifiers for Low Water Cut (<40%)
The water cut of crude oil can differ depending on various factors, and the demulsifier used is very much dependent on the condition of the crude oil. Croda has a range of demulsifiers which work especially well in crude oil with a low water cut.
