The invention provides a preparation method for a crude oil desalting agent. The preparation method comprises the following steps: 1) heating oxyethylene ether to 200 DEG C, adding acrylamide for a reaction, carrying out precipitation and taking out a precipitate; 2) freezing the precipitate obtained in the step 1) under the protection of nitrogen; and 3) adding organic phosphonic carboxylic acid and methacrylic acid into the precipitate, carrying out a stirring reaction for 1 h, then carrying out filtering and taking out a solution to prepare the crude oil desalting agent. The prepared crude oil desalting agent has the advantage of high desalting efficiency.
Description
technical field [0001] The invention belongs to the technical field of petrochemical industry, and in particular relates to a preparation method of a crude oil desalting agent. Background technique [0002] In the process of crude oil extraction, it carries a lot of sediment and contains salt, and the equipment with salt is easy to cause corrosion, and the salt scale will affect the heat transfer, increase the load, and affect the equipment. Currently, electric desalination is used. But the efficiency is low. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a method for preparing a crude oil desalting agent, which has the characteristics of high-efficiency desalting. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A kind of preparation method of crude oil desalting agent is characterized in that, com...
