Demulsifier
Product introduction
▶ UBPro-411 are formed by polymerizing ethylene oxide and propylene oxide in a mixed state under alkaline condition using phenol resin, polybasic alcohol, polyethylene polyamine as a starting the agent.
▶ It destabilizes water-in-oil emulsions and is useful as a component of dewatering and desalting formulations in the oil and related industries.
▶ It can be mixed with different solvents to produce water/oil soluble final demulsifier with different active ingredients.
To address the challenges of Low-temperature crude oil demulsification, heavy oil and ultra-heavy oil demulsification, tertiary produced liquid emulsified crude oil demulsification, Our engineers has designed the demulsifiers which have perfect desalination performance.
Applications/Functions
▶ Dilute the demulsifier to a suitable concentration with a suitable solvent before use (Such as: Aromatic Hydrocarbon), inject it into the end of the pipeline or inject it into the inlet line of the combined station dehydration tank, or into the dehydration tank with the crude oil for demulsification.
▶ To ensure the best results, a preferred experiment is required on the demulsifier model before use.
Recommended Handling
▶ The recommended dosage is 30 to 100ppm, while a pilot test is required for optimal results.
▶ All personnel handling this material must handle it as an industrial chemical, wearing protective equipment and observing the precautions as described in the Material Safety Data Sheet.
Packaging and Storage
▶ Packed in 200Litre drum or 1000 Liter IBC (Tote Tank).
▶ Store in dry, well-ventilated area. Keep container closed. Keep away from heat, sparks and flames. Store away from incompatibles. Follow safe warehousing practices regarding palletizing, banding, shrink-wrapping and /or stacking.

About Demulsifier
In the later stages of oilfield exploitation, crude oil emulsions are predominantly oil-in-water (O/W) systems, often coexisting with multiple emulsions and microemulsions. The produced liquid exhibits several challenging characteristics: high water content, free water containing oil and impurities, a deep degree of emulsification in water-containing crude oil, and significant difficulties in dehydration.
To tackle these issues effectively, a new type of demulsifier is essential. This demulsifier must possess a water-soluble, intelligently linked structure that is easy to disperse in crude oil and demonstrates good permeability, enabling it to reduce the oil content in desalted wastewater. Specifically, block copolymer demulsifiers are highlighted for this purpose. To ensure faster dehydration speeds and the maximum dehydration effect, the molecular design of these demulsifiers should incorporate an appropriate block sequence and chain segment length.

Demulsifier formulations usually combine water-soluble (such as fatty alcohol polyoxyethylene ether, triethanolamine) and oil-soluble (such as Basorol E 2032, TOMAC) components, and carrier solvents such as aromatic solvents are used to enhance solubility. Each component functions by promoting membrane drainage, emulsion de-stabilization and water phase separation. The optimization of the formula needs to determine the best combination through experiments based on specific emulsion conditions (such as temperature and pH).
It is recommended that users select appropriate combinations based on the properties of the oilfield emulsions (such as salinity, temperature, and asphaltene content)
