New DEMTROL 4000 and 5000 Series Crude Oil Demulsifier Bases<br />
Optimize Profitability, Minimize Environmental Impact<br />
<strong>Emulsion</strong> breaking is a critical processing step in any oil production scenario to help optimize profitability.<br />
As operators produce increasingly complex and heavier crude oil streams, new emulsion-breaking<br />
chemistries to process them quickly and cost effectively are needed.<br />
Committed to Continual Innovation<br />
Production chemical service companies have come to rely on Dow’s line of DEMTROL crude oil<br />
demulsifier bases to help them develop effective and economical processing solutions. Novel chemistries<br />
are required to treat new processing challenges, and Dow stands ready to assist with an R&D commitment<br />
to develop more efficient DEMTROL bases, such as our DEMTROL 5000 series.<br />
A next-generation demulsifier base built on Dow’s novel, patented polymer chemistry, the DEMTROL 5000<br />
series possesses several key attributes designed to make finding a solution to complex demulsifier<br />
<strong>for</strong>mulations easier:<br />
• 100 percent active, modified specialty resin alkoxylate chemistry – The new DEMTROL 5000<br />
bases are solvent-free and non-flammable (NFPA 704 rating of 1), making them inherently less hazardous<br />
compared to other solvent-containing, resin-based materials.<br />
• <strong>Cost</strong>-effective – Service companies can use and store lower volumes of DEMTROL 5000 bases than<br />
other solvent-based material and have greater flexibility to use the solvent of their choice in the final<br />
<strong>for</strong>mulation.<br />
• Per<strong>for</strong>ms multiple demulsification functions – DEMTROL 5000 bases can be used <strong>for</strong> efficient<br />
emulsion breaking and they optimize the quality of the water phase in many <strong>for</strong>mulations, which allows<br />
other bases to be omitted and simplifies the composition of the final product.<br />
• Separates oil and water efficiently – DEMTROL 5000 bases provide a unique combination of quick<br />
and effective separation of water from water-in-oil emulsions.<br />

1 The relative solubility number (RSN) was determined by titrating water in a solution containing 1g DEMTROL demulsifier and 30 ml toluene (2.6 vol%) and ethylene<br />
glycol methyl ether (97.4 vol%). RSN is reported as the volume of water needed to make a solution turbid or cloudy.

Bottle Test Results<br />
Bottle tests were per<strong>for</strong>med at 60°C on samples of API grade 12 crude oil with a basic sediment<br />
and water (BS&W) of 40. A demulsifier dosage of 60 parts per million was used. As shown in<br />
Figure 1, the DEMTROL 5150 crude oil demulsifier base exhibited faster water separation than a<br />
competitive <strong>for</strong>mulated product.<br />
