  4. Kemelix D511

Kemelix D511

Kemelix D511 is a concentrated polymeric alkoxylate. This product acts as an excellent demulsifier intermeidate, destabilising water-in-oil emulsions. This makes it a superior dehazer for use as a component in dewatering formulations. It also boasts exceptional desalting properties, removing salts and water from crude oil. Alongside it's demulsifying ability, Kemelix D511 exhibits emulsion preventative properties meaning it can also be used in non-emulsion formulations. Kemelix D511 has a high speed of action confirming it's suitability for separation vessels with shorter residence times. Due to Kemelix D511 being effective at low inclusion levels, there is a beneficial reduction in the cost of the final demulsifier formulation. Croda's reccomended crude oil demulsifier formulation for Kemelix D511 is 10-1000ppm.

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.
