Boost
performance on formulation.
Improve oil demulsification process.
Dow Corning provides silicone technology for oil producers and service
companies to improve their current crude oil demulsification process.
The Dow Corning® DMx line of silicone demulsifiers
represents a range of different structures and molecular weights which have
been proven effective in water/oil demulsification.
Silicone polyethers exhibit low surface tension (in some cases down to ? 21
dyn/cm compared to ? 30 dyn/cm for typical hydrocarbon surfactants in water)
and low cohesive energy; they are surface active in both aqueous and nonaqueous
media, and show inverse temperature solubility and cloud point. Some benefits
that can be achieved are rapid water drop rate, better interface definition,
better water quality, low temperature performance and overall improved cost
efficiency for demulsification operations.
The effectiveness of silicone demulsifiers has been demonstrated over the
years in the field, both as stand-alone additives and as performance boosters
to organic-based formulations, in levels between 10 – 30 wt%, based on
formulation active ingredients.
