Demulsifier Use for Oil Refining and Water Oil Separation Oilfield DemulsifierNegotiableMOQ: 20 Tons
A demulsifier is a surfactant that breaks up an emulsion. The demulsifier mainly destroys the emulsion by partially replacing the role of the stable film. Used as a dehydrating agent, it can remove the water in crude oil and heavy oil, so that the water content can meet the requirements; it can reduce the viscosity of crude oil when used in oil wells, so that the oil wells will not be blocked. It is obtained by polymerization of fatty alcohol, propylene oxide and ethylene oxide. Soluble in water, light yellow or milky white viscous liquid. Soap smell. Freezing point 25 ~ 40 ºC. Hydroxyl value ≤ 60 mg potassium hydroxide/g. , the aqueous solution is milky white.
Features
1. The demulsifier can play a good role in neutralizing charge, demulsification, bridging, adsorption, micelles and coalescence in crude oil emulsion.
2. Reduce the surface tension of the oil-water interface, which has the characteristics of fast dehydration speed, strong adaptability, high dehydration rate, less dosage, clear water quality, and strong compatibility with other chemical treatment agents.
3. Does not contain chlorine and will not damage oil products.
Instructions
1. The general dosage of the product is 50-100mg/L.
2. After the product is determined to be put into the production site, the dosing site must be determined according to the characteristics and needs of the production system. No matter what dosing process is used, it must be ensured that the medicine and the treatment liquid are fully mixed before entering the separation equipment.
3. Dosing is uniformly and continuously added to the system by a metering pump.
Usage
1. Adding 10-500ppm (the specific amount can be determined according to the experiment) to the oily wastewater, stirring for 1-2 minutes, the emulsion can be quickly broken.
2. Crude oil dehydration, adding 10-30g / L, stirring, can achieve oil-water separation, at 40-60 ºC, the effect is better.
3. The demulsifier has synergistic effect. After adding 5-100ppm PAC or PFAC or PFC, the water quality can be quickly cleared.
4. The amount of demulsifier and pH of wastewater can be adjusted to achieve the purpose of rapid demulsification and separation. The best pH is 6-7.
