Rotating packed bed (RPB), as a classical HiGee apparatus, has been proven to have great advantages for application in various chemical engineering fields, for it can provide large contact area between phases, faster surface renewal rate and more homogeneous nucleation sites, and so on. As research on HiGee technology has become more advanced, it is necessary to collate the various studies on the application of HiGee technology in different fields systematically. This work mainly reviews the research progresses of HiGee technology in synthesis of chemicals, preparation of particles, and separation in recent 5 years. Specifically, the latest applications of HiGee technology under different demands and novel structures of RPB designed for various working conditions are presented.

High gravity technology (Higee) aims to enhance mass transfer through the application of high centrifugal forces, presenting a promising approach to significantly reduce the size of distillation columns. However, Higee has not yet been fully integrated into distillation processes. A key reason for this limited application is that Higee devices need to be customized to meet the specific requirements of distillation. This article introduces a generally preferred Higee structure designed for this purpose, taking into account several critical considerations, including liquid distribution, dynamic sealing, intermediate feeding, and multirotor configurations. Most importantly, to tackle the longstanding issue of variable flow cross-sections in traditional Higee devices, an innovative rotor design with constant vapor flow area was proposed. This rotor, combined with the advantageous features of the favorable Higee structure, will open up new opportunities for the application of Higee technology in distillation processes.</div></div>","PeriodicalId":292,"journal":{"name":"Current Opinion in Chemical Engineering","volume":"47 ","pages":"Article 101058"},"PeriodicalIF":8.0,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142656921","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}
