Kemelix D400

Kemelix D400 is a modified polyol demulsifier intermediate which rapidly destabilises water-in-oil emulsions. It can be used as a component in dewatering and desalting formulations in both the oilfield and the refinery. Kemelix D400 works exhibits superior dehazer whe used as a component in dewatering formulations. Kemelix D400 is a fast acting demulsifier intermediate making it suitable for use in separation vessels with shorter residence times. Croda's reccomended crude oil demulsifier formulation for Kemelix D400 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 D400 can be found in the demulsifer function guide in the Demulsifiers brochure.

First Choice Demulsifiers for Light Oils (API>30)

The changing properties of oil recovered from one location to the next provide a challenge to service companies all over the world. For areas where the crude oil is lighter, we have developed a range of high performance demulsifiers which provide fast separation and a sharp interface.

First Choice Demulsifiers for Waste Oil Treatment

Waste oil streams are produced by several production and refinery operations, and it is often challenging to recover oil without disruption. Understanding that maximising oil recovery whilst keeping costs low is important to our customers, Croda has engineered a broad range of waste oil treatment chemicals that can be tailored to your particular conditions. Incorporating our chemistries into your formulations can provide a highly efficient treatment, allowing you to produce clean oil for recovery and high quality effluent water in a cost-effective way.
