Abstract

The invention discloses a preparation method of a demulsifier material. The preparation method comprises the following steps: producing a glass fiber mat by adopting glass fibers through a needle punching method and extending first glass fiber protrusions from two side surfaces of the glass fiber mat; cutting a plurality of meshes from the glass fiber mat, and then repeatedly towing and hooking the glass fibers on the side walls of the meshes so as to form second glass fiber protrusions extending to the inner parts of the meshes on the side walls of the meshes; calcining and cooling the glassfiber mesh mat, soaking, cleaning, hydroxylating, carrying out ultrasonic oscillation, then treating by using an aminosilane coupling agent and carrying out ultrasonic oscillation; immersing the glassfiber mesh mat into an aqueous solution of graphene oxide; drying; cutting the glass fiber mesh mat into cylindrical particles with the diameter of 5 to 10 mm and the thickness of 5 to 10 mm. The demulsifier material disclosed by the invention can obtain an excellent oil-water separating effect on crude oil and recycle the glass fiber mesh mat and the graphene oxide, so that pollution to the environment is reduced.

Description

technical field [0001] The invention relates to the technical field of petroleum processing, in particular to a preparation method of a demulsifier material. Background technique [0002] When crude oil is extracted, more than 80% of it will contain water to varying degrees, and some crude oil has a water content as high as 90%. If the crude oil is not dehydrated in time, it will increase the load on pumps, pipelines and storage tanks, causing corrosion and scaling on the metal surface; The oil contained in the discharged water will also cause waste of crude oil. Therefore, no matter from the economic point of view or from the point of view of environmental protection, it is necessary to carry out demulsification and dehydration of crude oil and deoiling of sewage. [0003] Crude oil demulsifier refers to the separation of oil-water emulsion into water and oil through the physical and chemical action of demulsifier, so as to realize the dehydration of crude oil and meet the...
