Kemelix D322
Kemelix D322 is an ethoxylated phenolic resin in an aromatic solvent. The product is an excellent demulsifier intermediate, destabilising water-in-oil emulsions. This makes it a superior desalter, removing salts and residual water from crude oil. Kemelix D322 also exhibits non-emulsifiying properties meaning it can also act to prevent emulsion formation. Kemelix D322 can be used as a component in dewatering and desalting formulations in both the oilfield and the refinery. Croda's reccomended crude oil demulsifier formulation for Kemelix D322 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 D322 can be found in the demulsifer function guide in the Demulsifiers brochure.
First Choice Demulsifiers for Heavy Oils (API<20)
Heavy oil regions are becoming increasingly attractive but present unique challenges in production, stimulation, transport and refining compared to lighter crudes. To support our customers in these challenges, we have developed a specific range of demulsifiers optimised for their performance with heavier crude oils.

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.
