In this study, ionic liquids (ILs) were incorporated into the separation process, thereby enabling energy-efficient styrene production through the use of extractive distillation. By solving a formulated mixed-integer nonlinear programming (MINLP) problem based on computer-aided ionic liquid design (CAILD), 1-methylpyridinium trifluoromethanesulfonate ([mPy][CF<sub>3</sub>SO<sub>3</sub>]) and 1-ethylpyridinium tetrafluoroborate ([C<sub>2</sub>Py][BF<sub>4</sub>]) were identified as optimal IL candidates for this application. Comprehensive process simulations and optimizations were conducted, focusing on energy consumption, environmental impact, and economic performance. In comparison to the conventional process, the [mPy][CF<sub>3</sub>SO<sub>3</sub>]-based and [C<sub>2</sub>Py][BF<sub>4</sub>]-based processes achieved reductions in energy consumption by 44.2 % and 59.0 %, respectively. Furthermore, there was a notable reduction in carbon emissions, amounting to 28.9 % and 25.4 %. However, processes utilizing [mPy][CF<sub>3</sub>SO<sub>3</sub>] showed an increase in total annual cost (TAC) by 11.8 %. Meanwhile, processes based on [C<sub>2</sub>Py][BF<sub>4</sub>] demonstrated a diminution in TAC by 3.7 %. Nonetheless, Monte Carlo simulations indicate that IL-based processes exhibit slightly better resilience to economic uncertainties compared to conventional processes. Overall, the significant energy and environmental benefits of IL-based processes highlight their potential in styrene production, especially with the implementation of active policies related to energy use and carbon emissions (e.g., carbon taxes).</p>","PeriodicalId":10083,"journal":{"name":"Chemical Engineering & Technology","volume":"48 4","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143861823","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}

Ammonia stands out as a viable zero-carbon marine fuel, owing to its carbon-free composition and higher energy density relative to hydrogen. This paper presents a thorough techno-economic analysis of a direct ammonia solid oxide fuel cell (SOFC) system, which is enhanced by a gas turbine (GT) and integrated with a multi-generation system, including proton exchange membrane fuel cells (PEMFC), organic Rankine cycle (ORC), Kalina cycle (KC), steam Rankine cycle (SRC), and waste heat boiler (WHB). The study employs a multi-stage approach that includes dynamic computational analysis, techno-economic evaluation, and assessments of environmental and social impacts to determine the optimal system implementation. Economic viability is evaluated through indicators such as net present value, internal rate of return and payback period, highlighting the critical role of fuel cell capital costs in investment feasibility, and repayment timelines. The levelized cost of electricity (LCOE) spans from 0.482 to 0.554 $ (kW h)<sup>−1</sup>, showing a variation of approximately 6.2 % from the average LCOE.

The mixtures can be classified into four groups, and six rules can be concluded for the change in the type of the nodes and saddles, if a new compound appears.
