This opinion article provides a short review of classic criteria applied to distinguish between runaway and nonrunaway states of reactors. Particularly, the significance of divergence criterion in the field of thermal runaway criteria is emphasized. In addition, to illustrate the general application procedures of the divergence criterion, examples of its utilization in three research domains, including process safety assessment, process parameter optimization, and process monitoring and control, are given.

This study evaluates the economic feasibility of developing nontraditional water for agriculture and identifies strategies to address the challenges by increasing affordability. In the Southwest United States, reuse of filtered disinfected municipal wastewater offers the most cost-effective option followed by desalinated brackish water, treated produced water, and seawater. High costs, energy demand, concentrate disposal, and soil salinity management are the primary challenges in using alternative water for irrigation. Economic feasibility can be enhanced by implementing autonomous, easy-to-operate, renewable energy-powered, decentralized desalination systems. The affordability of developing alternative water for irrigation will increase with reduced treatment and waste disposal costs, depletion of conventional irrigation water supplies, and droughts.</p></div>","PeriodicalId":292,"journal":{"name":"Current Opinion in Chemical Engineering","volume":"43 ","pages":"Article 100987"},"PeriodicalIF":6.6,"publicationDate":"2023-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138430305","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}
