The main components of oilfield reverse demulsifier for oily wastewater usually include the following categories:
1) surfactants-- Surfactants are an important component of reverse demulsifier/deoiler. Reverse demulsifier to treat oily wastewater can reduce the oil-water interfacial tension and make it easier for oil droplets and water droplets to separate. Different types of surfactants have different functional characteristics. Nonionic surfactants, Such as polyoxyethylene polyoxypropylene block copolymers, etc. This type of surfactant(Reverse Demulsifier/deoiler) has a good balance of hydrophilicity and hydrophobicity and can form a stable adsorption layer on the oil-water interface to promote the demulsification process. Cationic surfactants: With positive charges, they can interact with negatively charged emulsifiers to destroy the stability of the emulsion.
2) Polymers-- Polymers also play a key role in reverse demulsifier in oilfield. Polyacrylamide and its derivatives: With high molecular weight and good flocculation performance, the polymers of reverse demulsifier for oily wastewater can make tiny oil droplets aggregate into larger oil beads through adsorption, bridging and other effects, accelerating the separation of oil and water. Polyether polymers: With a special molecular structure, they can interact with the oil phase and the water phase, change the properties of the oil-water interface and promote demulsification.
3) Other auxiliary components--In order to improve the performance of reverse demulsifier in oilfield, some auxiliary components may also be added: Acid-base regulators: Used to adjust the pH value of the treatment system to optimize the demulsification effect. Cosolvents: Help other components dissolve better in water and improve the uniformity and stability of the reverse demulsifier.
Reverse demulsifier/deoiler agents are chemicals which used in various industries to separate water from oily wastewater, such as refineries and oil fields. The removal rate of oily wastewater can be as high as 99%.
Using reverse demulsifier for oily wastewater is a suitable solution in oilfield and refinery.
