Oily sludge is a hazardous waste inevitably generated during oil extraction and oil refining. The efficient separation and recycling of its petroleum hydrocarbons has been an important challenge for the petrochemical industry. Despite the rapid advancement of oil sludge normal temperature separation technology, with the popularity of polymer-driven oil and tertiary oil recovery methods, the nature of oil sludge varies and emulsion complexity increases, necessitating urgent investigations into the intrinsic difficulties, process enhancements, and future directions of oil sludge normal temperature separation. The causes of sludge separation challenges including the macroscopic components of the sludge and microscopic interfacial interactions during treatment are systematically summarized. And the main oil sludge separation processes, mechanisms and application scenarios at normal temperature are systematically described in this work. Aiming at the problems of low index of single pathway, high solid content in recovered oil and cumbersome compounding process in oil sludge separation, a few new technologies of oil sludge at normal temperature are proposed, including biosurfactant treatment of oil sludge, environmentally responsive ionic liquid microemulsion treatment of oil sludge, environmentally responsive emulsion treatment of oil sludge, and environmentally responsive magnetic nanoparticle solution disposal of oil sludge. It also suggests new approaches to the oil sludge disposal process, such as targeted regulation of the oil sludge emulsion interface, combined process design of environmentally responsive agents, elaboration of the integrated mechanism of action of oil sludge emulsification and demulsification, and standardization of the oil sludge separation assessment system. The resolution of the above fundamental scientific and technological problems will provide a strong guarantee for the reduction of environmental pollution and the promotion of high-quality development of the petrochemical industry.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"12 6","pages":"Article 114329"},"PeriodicalIF":7.4,"publicationDate":"2024-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142416122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These processes primarily involve intermolecular interactions and the molecular arrangement within urea. Understanding polymorphism facilitates modification of the physical and chemical properties of urea compounds. Polymorphism refers to a compound's ability to exist in different forms or crystal structures. Urea exhibits five distinct polymorphic forms under specific temperature and pressure conditions and extensive research has been conducted on the unit cell parameters of different phases of urea. In the realm of urea cocrystal development, polymorphism plays a significant role. Urea cocrystals typically consist of urea molecules and one or more additional molecules, strategically chosen to modify urea's properties for broader applications. The preparation of cocrystals involves mixing pure urea with the chosen coformer under controlled atmospheric conditions. Cocrystal formation can be enhanced through the application of mechanical forces to the reactants, elevated temperatures, and specific relative humidities. The field of cocrystallization provides a powerful toolkit for crafting desirable urea compounds, making them well-suited for applications in agriculture and other industries. In pharmaceuticals, cocrystals with urea allow for the design of more effective and easily administered medications which can enhance drug delivery and absorption. In agriculture, urea cocrystals can optimize the release of nitrogen from urea fertilizers, improving nutrient uptake by plants, and reducing environmental impact. In addition, cocrystals often utilize industrial byproducts or waste materials as coformers to modify the properties of urea. Furthermore, preparing urea cocrystals using solvent-free mechanochemistry eliminates the need for solution handling and evaporation, promoting an environmentally sustainable process.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"12 6","pages":"Article 114308"},"PeriodicalIF":7.4,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142416114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
