API gravity of the Crude
API Gravity acts like an "intelligence agent"—through it, we can infer many critical factors that directly affect the difficulty of demulsification:
1. Overall Composition of Crude Oil and Emulsion Tendency.
2. Viscosity of Crude Oil and Required Processing Temperature.
3. Types of Potential Solid Impurities.
4. Direction for Demulsifier Formulation Design. -
Operating Conditions
1. What is the temperature range of your oilfield operations? (Demulsifier performance may be affected by temperature)2. What type of separation equipment do you use? (E.g., gravity settling tanks, electrostatic dehydrators, etc., as different equipment may require different demulsifiers)3. How quickly do you need the demulsification process to occur? (Rapid demulsification may require specific formulations) -
Specific Requirements
What are your specific requirements for demulsification efficiency? (E.g., residual water content in crude oil or oil content in wastewater after separation)Do you need the demulsifier to also provide desalting or solid particle removal functions?
Dosage and Application Method？Do you have any expectations or limitations regarding the dosage of the demulsifier? (This relates to operational costs and convenience)
And when we select the solvent for demulsifier, basicly, the active ingradient can totally solve in the solvent, and we should consider the molecular weight, which infect the disperse speed in different API crudes. That's why the API matters.
By combining API Gravity with other key information (BS&W, water quality (salinity), temperature, types of produced solids, etc.), We can provide customers with a highly customized, efficient, and economical demulsification solution.
how are our emulsion breakers are designed?
Based on the API gravity of the target crude oil (light vs. heavy), BS&W (indicating the level of solid content), and demulsification operating conditions (temperature, pressure: high-temperature operations require the demulsifier and its solvent to possess excellent thermal stability), demulsifiers are customized as follows:
Functional groups of varying numbers and molecular weights are selected as initiators. Under specific conditions, different ratios (to adjust the demulsifier's HLB value—Hydrophilic-Lipophilic Balance) and sequences of PO (lipophilic head) and EO (hydrophilic head) are incorporated to form polymer chains of varying lengths (longer chain segments enhance the molecule's lipophilicity or hydrophilicity). Subsequently, solvents with appropriate molecular weights (capable of fully dissolving the demulsifier, exhibiting suitable viscosity for pumping and injection, avoiding secondary emulsification or precipitation, possessing appropriate flash points, and ensuring safety and environmental friendliness) are selected to finalize the demulsifier design.

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.
Attentions:
This demusifier UBPro-411 has been applied in China oilfield and Southeast of Asia, to solve the low temperature problems, the methyl alcohol is added to the UBPro-411 ,methyl alcohol makes it get a low flash point, which makes it a dangerous good, but our experienced engineers will help on this, please contact us for more information.

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)
