Demulsifier

Types: Water Soluble Demulsifier, Oil-soluble Demulsifier, Low temperature demulsifier, Reverse Demulsifier.

Water Soluble Demulsifier

It is a type of water soluble non-ionic surfactant that applied in refining crude oil pretreatment process to improve oil/water separation. It mainly helps to resolve the water/oil emulsion in the desalter to effectively reduce water and salt content in the desalted crude, to achieve removal of corrosive species and bring benefits for downstream unit corrosion control.

Product features and effects:

a、Promote water/oil fast separation, optimize desalting efficiency, help reduce potential corrosive species for crude distillation unit.

b、Control emulsion rag layer and establish clear oil/water interface.

c、Control oil content in brine effluent to reduce crude lost and ensure effluent in specification for discharge.

d、Help to lower desalting total operation cost.

Injection and Dosage:

The chemical should be injected into each individual desalter through wash water line. The dosage should be decided based on crude oil properties. SANTACC sales rep and technical representative will provide you more detail information regarding the application method and dosage.

Physical and Chemical Properties:

Oil-soluble Demulsifier

It is a type of hydrocarbon soluble non-ionic surfactant that applied in refining crude oil pretreatment process to improve oil/water separation. It mainly helps to resolve the water/oil emulsion in the desalter to effectively reduce water and salt content in the desalted crude, to achieve removal of corrosive species and bring benefits for downstream unit corrosion control.

Product Benefit:

a、Promote water/oil fast separation, optimize desalting efficiency, help reduce potential corrosive species for crude distillation unit.

b、Control emulsion rag layer and establish clear oil/water interface.

c、Control oil content in brine effluent to reduce crude lost and ensure effluent in specification for discharge.

d、Help to lower desalting total operation cost.

e、Improve crude treatment feed flexibility while keeping desalted specification.

f、High flash point, reduce shipping and storage risk.

Injection and Dosage:

The chemical should be injected into the crude oil line on the crude charge pump side. The dosage should be decided based on crude oil properties, process operation condition. SANTACC sales and technical representative will provide you more detail information regarding the application method and dosage.

Physical and Chemical Properties:

Low temperature demulsifier

It is mainly used as oil soluble surfactant in refinery crude oil tank area to improve oil water separation efficiency under low temperature storage condition. In order to meet the requirement of water and salt content of the refinery's electric desalting crude oil feed, the high water content material should be dehydrated, and the content of mechanical impurities in the material should be partially reduced.

Product features and effects:

a、 Control water content in crude oil to meet the requirements of electric desalination feeding.

b、Reduce and control the salt content in the electric desalination feed to reduce the operating pressure of electric desalination.

c、Provide overall benefits of the system by reducing the water and salt content of the feedstock.

d、Improve the flexibility of processing material oils while maintaining the index of water content and salt content after removal.

Injection and dose:

The crude oil storage tank is usually injected through a crude oil pipeline. The specific amount of injection must be determined according to the nature of the oil and the pretreatment index. You can consult to the service personnel of SANTACC to know the relevant program parameters and recommended injection dosage and injection method.

Physical and Chemical Properties:

Reverse Demulsifier

It is a type of high molecular weight, mostly cationic polymer surfactant applied for oil/water separation in reserved emulsion environment. It can neutralize the negative charges on the oil droplet surface and reduce oil/water interface tension and electrostatic repulsion. It can help to recollect the oil from broken emulsion, clarify discharged water and so widely used in refinery or oilfield.

Features and advantages:

a、Applied to wide pH range environment

b、Safe, less toxic and biodegradable, keep minor environment impact

Physical and Chemical Properties:

Colorless to light yellow, freezing point≤0℃,Flash point≥30℃
