Oil Sludge Demulsifier for Emulsion Breaking and Oil Recovery

GN-MINE Series

GN Oil Sludge Demulsifier is a specialty chemical formulated to destabilize persistent water-in-oil and oil-in-water emulsions in oily sludge treatment. It promotes rapid phase separation, improves recovered-oil quality, and helps reduce oil content in separated water and solids. Product selection should be based on laboratory bottle testing using representative sludge samples and actual operating conditions.

GN New Chem supplies Oil Sludge Demulsifier for refineries, oilfield service companies, environmental service contractors and sludge treatment operators that require reliable oil-water separation under demanding conditions. Suitable formulations can be selected according to crude-oil characteristics, water cut, asphaltene content, solids concentration, salinity, temperature, emulsion stability, mixing intensity and the downstream separation process.

Product Overview

Oil Sludge Demulsifier is designed to break stable emulsions that trap oil, water and fine solids together in oily sludge. By weakening the interfacial film around dispersed droplets, the demulsifier promotes droplet coalescence and faster oil-water disengagement. This can improve free-oil recovery, water clarification and the performance of downstream separation equipment such as decanter centrifuges, three-phase centrifuges and gravity separation systems.

Because oily sludge composition varies significantly between crude oils, storage tanks, refinery processes and treatment plants, there is no universal dosage or formulation. The recommended Oil Sludge Demulsifier grade should be confirmed through laboratory screening and, where practical, a controlled field trial before routine application.

Main Functions

• Break stable water-in-oil and oil-in-water emulsions in oily sludge.
• Promote rapid oil-water phase separation and improve free-oil recovery.
• Help reduce residual oil in separated water and solids when used with an optimized treatment process.
• Improve feed conditioning for centrifugation, gravity separation and thermal washing systems.
• Support more stable downstream operation by reducing emulsion-related separation problems.
• Help optimize total treatment cost through proper demulsifier selection and dosage control.

Features and Advantages

• Application-specific formulation: Demulsifier grades can be selected according to crude type, sludge composition, emulsion structure and process conditions.
• Fast emulsion breaking: Promotes droplet coalescence and phase disengagement to support efficient oil recovery.
• Good process compatibility: Can be evaluated for use with heating, dilution, washing, centrifugation and other oily sludge treatment steps.
• Flexible product selection: Different formulations can be screened for varying temperature, salinity, solids content and emulsion stability.
• Laboratory and field evaluation support: Bottle testing, comparative screening and dosage optimization can be arranged according to project requirements.
• Integrated treatment knowledge: GN New Chem combines chemical application experience with practical understanding of solids-liquid separation equipment and oily sludge treatment systems.

Typical Applications

GN Oil Sludge Demulsifier can be used in a range of oily sludge and oil recovery processes, including:

• Refinery tank bottom sludge treatment.
• Crude oil storage tank sludge treatment.
• Oilfield oily sludge and drilling waste treatment.
• Thermal washing and hot-water washing systems.
• Decanter centrifuge and three-phase centrifuge separation.
• Gravity settling and oil-water separation systems.
• Recovered-oil polishing and oil recovery processes.
• Other industrial oily waste streams where stable emulsions limit oil-water separation.

Recommended Use

1. Analyze the oily sludge sample and define the treatment objective, such as increased oil recovery, improved water quality or reduced residual oil in solids.
2. Screen candidate Oil Sludge Demulsifier grades by bottle testing with representative samples.
3. Evaluate the influence of temperature, dilution ratio, pH, mixing intensity and retention time where relevant.
4. Dose the selected demulsifier at a point that provides sufficient dispersion and contact without excessive shear after floc formation or phase coalescence begins.
5. Start from the laboratory-derived dosage range and optimize gradually according to separation speed, interface quality, recovered-oil quality and downstream equipment performance.
6. Confirm stable performance through a controlled field trial before establishing the routine chemical program.

Always follow the approved TDS, SDS, site chemical-management procedures and applicable local regulations. The optimum dosage of Oil Sludge Demulsifier is system-specific and should be determined through testing rather than by a generic fixed dosage.

Packaging, Storage and Transportation

• Packaging: 25 L pail or 200 L drum. Other packaging options may be available depending on order quantity and product grade.
• Store in the original sealed package in a dry, well-ventilated area, protected from direct sunlight, contamination, incompatible materials and extreme temperatures. Prevent freezing where applicable.
• Transportation classification, labeling and shipping documentation will be confirmed according to the final formulation, destination country and transport method.

Information Needed for Product Selection

• Source of the oily sludge and treatment objective.
• Representative sludge sample and available laboratory analysis.
• Oil, water and solids content of the feed.
• Crude-oil type, density or API gravity where available.
• Emulsion type and observed emulsion stability.
• Asphaltene, wax or other heavy-organic content where relevant.
• Operating temperature, pH, salinity and any dilution or washing-water conditions.
• Existing chemical program, current demulsifier grade, dosage and performance.
• Process flow, mixing method, retention time and downstream separation equipment.
• Target oil recovery, separated-water quality and residual-oil requirement for solids.
• Estimated daily or monthly chemical consumption, preferred packaging and delivery destination.
