7results about How to "Good demulsification effect" patented technology

The application discloses a kind of pure natural demulsification granules preparation method and its application method, comprising the following steps: selecting dry lotus, the lotus is segmented, the segmented lotus is sent into pulverizer and broken into powder, the final powder is screened by screen mesh, the raw material of powder passing through screen mesh is obtained, lotus powder is obtained, finally lotus powder is placed in oven and dried, it is demulsification granule, the method utilizes the composition characteristics of dry lotus powder with oil-water amphiphilic, the hydrophobic part of lotus can be combined with the oil-loving group in surfactant, thereby causing the rupture of emulsion interface, so that oil droplets in rolling oil emulsion cannot be stably dispersed in water phase, the balance of oil phase and water phase in emulsion is destroyed, and finally the effect of demulsification is achieved, and after demulsification is completed, the property of plant granule is not easy to change, even if oscillation, it is also not easy to emulsify again, and the use time of the whole demulsification is shorter, and the solution is stable.

The application belongs to the technical field of demulsification dehydration, and discloses a preparation method of a demulsifier and application of the demulsifier in asphalt mixture. The preparation method of the demulsifier comprises the following steps: reacting acidified clay minerals with gamma-methacryloxypropyltrimethoxysilane to obtain modified clay minerals; reacting the modified clay minerals with triethylenetetramine to obtain polyamine-based clay minerals; and reacting the polyamine-based clay minerals with bromohexadecane to obtain the demulsifier. The demulsifier is a polyquaternary ammonium salt type cationic demulsifier. Through the positive charges of cations contained on the surface of the clay minerals and quaternary ammonium salts, the double electric layer structure of the surface of anionic emulsified asphalt is changed, the thickness of the double electric layer is compressed, the electrostatic repulsion between the emulsified asphalts is reduced, and the demulsification effect is good. When the asphalt mixture is prepared, the adhesion of asphalt particles to aggregates can be effectively promoted, the water in the asphalt mixture can be effectively discharged, and the solidification and molding of the asphalt mixture can be accelerated.

This application relates to the field of demulsifiers, and more specifically, to an oil sludge demulsifier, its preparation method, and its application. An oil sludge demulsifier comprises the following components in the following mass ratio: 20-35 parts of a surfactant complex, 7-12 parts of an alkyl sulfate sodium cosolvent, 0.6-1.8 parts of a stabilizer, and 48-55 parts of water; wherein the surfactant complex comprises hyperbranched polyamide amine and polyether amine modified magnetic nanoparticles. This oil sludge demulsifier improves upon the problems of existing demulsifiers, such as low dehydration capacity, slow dehydration speed, poor demulsification effect, and low oil content, thereby improving the demulsification performance and dehydration efficiency, and achieving effective separation of oil sludge.

The invention discloses a filter pressing treatment process for oily sludge, and belongs to the technical field of oil and gas field waste treatment. Comprising the following steps: feeding the oily sludge into a preheating tempering tank, adding alkyl glycoside and amorphous silicon powder, and carrying out gradient heating and stirring to obtain pretreated sludge; then feeding the pretreated sludge into a mixing reactor, adding a composite modified filter aid prepared from hydrophobic modified diatomite, quaternized modified chitosan, aminated modified graphene oxide and the like, and performing stirring-ultrasonic treatment to obtain demulsified sludge; feeding the demulsified sludge into a filter press which is pre-coated with a porous non-hydrophobized diatomite pre-coating layer and is provided with double-layer breathable gradient aperture filter cloth, and finally, performing low-pressure material distribution and gradient boosting filter pressing, and after filter pressing, introducing instantaneous high-pressure nitrogen to perform micro back-flushing and cake unloading, and purging the filter cloth to complete the operation. According to the process, an oil-water-silicon fine particle emulsification system can be effectively broken and removed, the problems of high-altitude low-temperature agglomeration and system microphase separation are relieved, graded interception and blockage prevention are realized, and the filter pressing efficiency and stability are improved.

The present application relates to the technical field of petroleum chemical industry, and particularly relates to a biochemical composite demulsifier, which comprises a microbial demulsifier and a chemical demulsifier, wherein the microbial demulsifier is prepared from a fermentation liquor of pseudomonas aeruginosa, and the chemical demulsifier is a mixture of trimethylolpropane polyether and epoxy polyether, and has the advantages of excellent demulsification effect and low cost.

The application provides a high-efficiency treatment and sludge concentration device for fracturing flowback fluid, which comprises an electric flocculator, a settling cylinder and a cyclone pipe. The electric flocculator comprises a plurality of flocculation tubes arranged side by side and connected in series, a U-shaped joint connected between adjacent flocculation tubes, and a power supply for supplying power to the flocculation tubes. The settling cylinder is used for separating oil, water and mud in the fracturing flowback fluid. The cyclone pipe is connected to the outlet end of the electric flocculator and extends into the settling cylinder along the tangent direction of the cross section of the settling cylinder. The electric flocculator and the settling cylinder are arranged. The electric flocculator breaks the emulsification of the fracturing flowback fluid, and flocculates the oil droplets, suspended impurities and solid impurities in the fracturing flowback fluid into flocs, so that the oil, water and mud can be separated by the subsequent settling cylinder.
