| titleOfInvention | Demulsifying agent for separation of oil-in-water emulsion system and preparation method and application thereof |
| abstract | The invention discloses a demulsifying agent for separation of an oil-in-water emulsion system and a preparation method and application thereof. The method includes the steps that 1, chitosan and acid are mixed to obtain a chitosan solution; 2, polymethylacrylamide and the chitosan solution are mixed and stand to obtain chitosan-polymethylacrylamide hydrogel; 3, the chitosan-polymethylacrylamide hydrogel is subjected to freeze-drying treatment to obtain the demulsifying agent. The demulsifying agent is convenient to prepare, easy to operate, environmentally friendly, good in stability and capable of being prepared on a large scale. Demulsifying is achieved through the absorption-extrusion process of the demulsifying agent, and the demulsifying agent is applicable to demulsifying separation of the oil-in-water emulsion system, overcomes the defect that demulsifying particles can not be continuously treated, and also solves the problem that when a filtration type demulsifying net film is repeatedly used, emulsion blocks micropores and contaminates the net film, and consequently separation efficiency is greatly reduced. |
