Therefore, an evaluation method for energy conservation and emission reduction of distributed energy systems is proposed, which considers system dynamics and demand response. According to the requirements of system dynamics analysis, the relational variables in the system dynamics model are determined. The input-output relationship of energy saving, and emission reduction effect evaluation is described by system dynamics equation, and the input-output relationship of energy saving, and emission reduction effect evaluation is determined. Based on the maximum profit objective function and the minimum cost objective function of the user, the continuum equation of the medium transmission process in the distributed energy system is obtained. The evaluation indexes of energy saving, and emission reduction effect are selected from the three aspects of power consumption side, power generation side and the system itself to realize the evaluation of energy saving and emission reduction effect. The experimental results show that the evaluation curve obtained by this method is basically consistent with the actual curve, and the evaluation accuracy is high.","PeriodicalId":11704,"journal":{"name":"Environmental Engineering Research","volume":"59 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2023-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139287174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Li is conventionally extracted as Li<sub>2</sub>CO<sub>3</sub> using sodium carbonate (Na<sub>2</sub>CO<sub>3</sub>) to precipitate Li ions in an aqueous Li solution. However, Na<sub>2</sub>CO<sub>3</sub> can also be replaced by CO<sub>2</sub>, which highlights the potential of using CO<sub>2</sub> as a sustainable and economically viable alternative. This review focuses on technologies that utilize CO<sub>2</sub> for Li<sub>2</sub>CO<sub>2</sub> precipitation. First, the use of CO<sub>2</sub> gas and Na<sub>2</sub>CO<sub>3</sub> as carbonate sources are compared, and the need to consider important operating conditions with CO<sub>2</sub> bubbling are then presented. Attempts made to increase the specific surface area of the reaction surface to enhance the utilization of CO<sub>2</sub> gas and to produce micro-sized Li<sub>2</sub>CO<sub>3</sub> powders are then reported, and the limitations associated with CO<sub>2</sub> gas utilization are discussed. Although CO<sub>2</sub> precipitation has limitations in terms of efficiency, scalability, and the fine-tuning of reaction conditions, this review shows that if CO<sub>2</sub> precipitation technology is further developed, its use could be key to extracting and recycling next-generation Li.","PeriodicalId":11704,"journal":{"name":"Environmental Engineering Research","volume":"11 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2023-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139315139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
