Oil production chemicals

Demulsifier intermediates

Emulsion breaking is one of the most complex and situational aspects of oilfield chemistry. Stable emulsions encountered in oil production are normally composed of varying levels of water or brine dispersed in a continuous oil phase. Furthermore, these emulsions are stabilised by compounds occurring naturally in the crude. Certain types of operations in refinery practice also produce stable emulsions.

To facilitate the economical removal of water from crude oil, we can offer demulsifiers that can treat a wide range of emulsions under the most demanding field conditions including where there is high turbulence, high solid loadings, low temperatures and high-water content. These products provide:

• Outstanding, rapid water separation, particularly in heavy oil applications
• Reduced treating costs & smoother operation
• Excellent low temperature performance
• Improved downstream operations
• Drier oil, cleaner water and sharper interface
• A superior environmental profile.

Green demulsifiers

Sustainability is embedded in our strategic thinking and we take our environmental responsibilities seriously, recognising the increased awareness our customers have on the impact of chemicals on the environment.

We recognise the increased environmental requirements of our products, particularly under The Activities Regulation in Norway and Offshore Chemical Notification Scheme (OCNS) as implemented in the UK and Netherlands. We have three green demulsifiers:

• Kemelix™ 3697X
• Kemelix™ 3702X
• Kemelix™ 3725X.

All have been tested for biodegradability and their effect on skeletonema costatum growth rate using standard test methods for Harmonised Offshore Chemical Notification Format (HOCNF), the results of which indicate that these products would be rated yellow for use in the Norwegian sector.

As well as having comparable standard demulsifier performance, our green demulsifiers also meet the following criteria:

• Good environmental profile without compromising on performance
• REACH and TSCA exempt
• Inherently biodegradable under HOCNF approval test methods
• Low aquatic toxicity
• Non-bioaccumulating.
