Demulsifier& Reverse Demulsifier For Crude Dehydration

Demulsifier compositions is a product which is formed by the block polyether of ethylene oxide and propylene oxide. Demulsifier additive for oily sludge, especially fast acting emulsion breaker has a unique function in dehydration. Demulsifier compositions for crude dehydration with different parameters depend on the block polyether of ethylene oxide and propylene oxide.

Our company's technical engineer could visit the clients' spot to supply technical service about demulsifier additive for oily sludge, and then free samples could be delivered to clients. Demulsifier additive compositions are formulated depending on various oil parameters from these spots. 

"One spot and one composition" --This is a customized solution of demulsifier compositions for crude dehydration such as fast acting emulsion breaker is different from other demulsifier additive compositions. Like fast acting emulsion breaker, this type of demulsifier additive composition is always packed by drum or IBC, which is used for demulsifier additive for oily sludge treatment in the oilfield and has stable performance and a shelf time of 12 Months.

Cross linked phenolic amine block polyether demulsifieradditive for oily sludge is mainly applied to demulsification and dehydration in crude oil extraction and gathering transportation. 

During crude oil extraction, especially for heavy oil and high water cut crude oil, formation water and injected water form stable W/O emulsions with crude oil, with a water content that can reach 30%-80%. It is necessary to remove water to reduce transportation energy consumption and avoid equipment corrosion. 

The cross linked structure of demulsifier compositions enables it to maintain activity under high-temperature (60-120℃), high salinity (mineralization degree > 10⁴ mg/L) and high shear (pipeline transportation) conditions, making it suitable for harsh scenarios such as offshore oilfields and heavy oil thermal recovery. 

Meanwhile, it has a fast acting emulsion breaker demulsification speed (30-60 minutes), a dewatering rate of over 90%, and the water content of the dehydrated crude oil is less than 0.5%, meeting the transportation standard. 

In oil containing wastewater such as oilfield produced water and operational wastewater, the oil exists in the form of O/W emulsions (oil droplet particle size < 10μm), and traditional treatment methods (such as oil separation and flotation) are difficult to achieve complete separation. As a demulsifier additive for oily sludge, the cross linked phenolic amine block polyether can disrupt the emulsification film on the surface of oil droplets, causing small oil droplets to aggregate into large ones. Then, combined with processes such as coagulation and filtration, the oil content can be reduced to less than 5 mg/L, meeting the discharge standard. 

The demulsifier compositions for crude dehydration has strong adaptability to polymer containing (such as polyacrylamide) flooding production wastewater and can break the composite emulsion formed by the polymer and oil simultaneously.
