We investigated the influence of impurities, pipe inclination, and heat transfer between the CO<span><math><msub><mrow></mrow><mrow><mn>2</mn></mrow></msub></math></span>-rich stream and its surroundings. The network model was solved using the Newton loop-node method coupled with the non-pipe element model in matrix notation. The model was benchmarked against a commercially available hydraulic modeling software package using data from a fictitious but plausible multi-source transmission system. The applicability of the model was demonstrated through a case study of a complex meshed network. The results indicated a good agreement between the software tools, but the proposed model showed a two orders of magnitude smaller computational burden. The model also showed superior insensitivity to the topology of the computed network in terms of computational complexity.</div></div>","PeriodicalId":334,"journal":{"name":"International Journal of Greenhouse Gas Control","volume":"149 ","pages":"Article 104567"},"PeriodicalIF":5.2,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145920742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
