Demulsifier additive chemical breaks the crude oil emulsion into crude oil and water. additive breaks the water/oil emulsion by maintaining a strict hydrophilic-lipophilic balance (“HLB” scale).
additive chemical to oilfield water/oil emulsion alters the kinetic stability by changing the interfacial film encapsulating the water droplets allowing the coalescence of the water droplets separate from the crude oil. The result is demulsification of the crude oil mass by additive chemical.
Demulsification of the crude oil mass by Demulsifier additive chemical involves many different theories of physiochemical mechanisms. New chemistry has been developed by OilFlux™ for demulsification of the crude oil mass by Demulsifier additive chemical.
Demulsification can be achieved by Demulsifier additive chemical alone or in conjunction with mechanical processes such as agitation, temperature, pressure, electrostatic fields, or altering flow velocity. Demulsification by Demulsifier additive chemical must be carefully designed and used in accordance with crude oil API type, temperature, pH, brine composition, water droplet size and distribution, agitation, residency time, dosage and similar factors.
Demulsifier additive chemical efficacy is tested by the difference on water content according to ASTM D-95/13e1 method on a sample crude oil before and after testing.
OilFlux™ “SWO” demulsifier additive tested according to ASTM D-95/13e1 with a 0.5% dosage by crude oil volume resulted in a 62.5% reduction of water which achieved refinery specifications of less than 0.2% for basic sediment and water (“BS&W”) and 10 pounds of salt/1000 bbl of crude oil.
The test was performed by the world renowned independent laboratory, Intertek
