Overview
Liquid demulsifier is a specialized chemical formulation designed to separate emulsions, particularly those involving oil and water. It is widely used in industries where efficient phase separation is critical, such as petroleum extraction, wastewater treatment, and chemical processing. The effectiveness of liquid demulsifiers stems from their ability to destabilize the interfacial film between oil and water droplets, promoting coalescence and separation. These agents are tailored to specific emulsion types, ensuring optimal performance in diverse industrial applications.
Physical and Chemical Properties
Liquid demulsifiers typically exhibit a clear to slightly cloudy appearance with a density ranging from 0.9 to 1.1 g/cm³. Their solubility in both water and organic solvents makes them versatile for various emulsion systems. The chemical composition varies depending on the intended application, but most formulations include surfactants and polymers that disrupt emulsion stability. Key properties include fast action, low toxicity, and compatibility with industrial processes.
Main Applications
In the petroleum industry, liquid demulsifiers are essential for crude oil dehydration and desalting processes. They help separate water from crude oil, improving quality and reducing corrosion risks in pipelines and refineries. Wastewater treatment plants utilize these agents to break oil-water emulsions, facilitating cleaner effluent discharge. Additionally, chemical manufacturing processes often require demulsifiers to recover valuable products from emulsion byproducts.
Safety and Storage
While generally low in toxicity, liquid demulsifiers require proper handling to prevent skin and eye irritation. Workers should use protective equipment, including gloves and goggles, when handling these chemicals. Storage should be in a cool, dry place away from direct sunlight to maintain product stability. Containers must be tightly sealed to prevent contamination and evaporation. Spill management protocols should be in place due to potential slip hazards.
B2B Procurement Guide
When procuring liquid demulsifiers, buyers should first identify the specific emulsion characteristics they need to address. Compatibility tests with the target emulsion system are recommended before large-scale purchases. Reputable suppliers should provide technical data sheets and safety information. Bulk purchases typically offer cost advantages, with prices ranging approximately $500-$2000 per ton depending on formulation and quantity. Consider suppliers with industry certifications and proven track records in your specific application area.
