Since these metals are considered critical and due to their abundance in Brazilian territory, the Brazilian government and mining companies must master the refining of these metals through autochthonous technologies. Thus, we developed a process to separate the light (La, Ce, Pr and Nd) from the medium (Sm, Eu and Gd) and heavy (Tb-Lu and Y) rare earth elements (REE) with D<sub>2</sub>EHPA by empirical modeling of solvent extraction (SX) processes. The experimental methodology included three phases: equilibrium data acquisition from batch experiments, solvent extraction simulation, and continuous process trials to validate the model on a mini-pilot scale. Our simulation predicted 99.5% Sm organic recovery and 80% Nd aqueous recovery in a seven-stage process and 0.30 A/O ratio, validated in the continuous trial. This work paves the way for establishing Brazilian technology to obtain the constituent elements of permanent magnets.</p>","PeriodicalId":9194,"journal":{"name":"Brazilian Journal of Chemical Engineering","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2023-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138513549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Enhanced oil recovery (EOR) methods are applied to modify fluid–fluid and fluid–rock interactions in the reservoir, facilitating the oil displacement and, consequently, increasing the recovery factor. In this work, the use of silica nanofluids as EOR method to reduce the IFT and to change the wettability conditions of reservoir rock were evaluated. For experimental tests, crude oil from a reservoir in a Brazilian Pre-salt field was used as oleic phase. No significant change in IFT was observed with an increase in the concentration of SiNPs for both distilled water and low salinity water (1000 ppm) dispersant fluids. The significant reduction of the contact angle is observed for nanofluids with 0.02 wt% SiNP. Finally, the Amott test was performed in a carbonate rock sample to reaffirm the action of these chemicals in oil recovery, corroborating the potential of nanofluids to EOR applications. Thus, this work might contribute to a more rational design of nanoEOR strategies and technological innovations in carbonate reservoirs, especially those addressed to the South American Deepwater sector.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":9194,"journal":{"name":"Brazilian Journal of Chemical Engineering","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2023-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138513541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
