However, dimethyl ether production from methanol typically suffers from intense energy consumption, high CO2 emissions, and large costs. Advanced distillation technologies, particularly reactive distillation (RD) and dividing-wall column (DWC), are potentially capable of addressing such issues. The present study evaluates the techno-economic performance of those advanced distillation technologies by accounting for a complete set of reaction and separation functions and an identical catalyst, i.e., Amberlyst-35, for each process configuration. The use of a common catalyst ensures that the identified performance differences are attributable to the technology configurations themselves rather than the variations in catalyst type. The finding interestingly suggests that the DWC scheme outperforms both conventional reactor-distillation and RD schemes. The specific energy consumptions for the conventional, RD and DWC schemes are 1.74, 4.10 and 1.41 GJ/ton, respectively, while the CO2 emissions for those schemes are 0.09, 0.22 and 0.08 tons CO2/ton, respectively.

Recently, droplet manipulation strategy using thermocapillary convection has received attention due to its precise and remote controllability. The mobility of liquid droplets in this method depends on several parameters, such as laser power and the light absorption coefficient. Additionally, surface tension significantly influences droplet movement although its underlying mechanism remains unclear. In this study, we investigate the effect of surface tension on droplet movement via thermocapillary convection. Aqueous dispersions of polypyrrole (PPy) nanoparticles (NPs), which absorb near-infrared (NIR) light and convert it into heat, are employed as droplets. Upon NIR laser irradiation, the PPy droplets generate localized heat, resulting in thermocapillary convection. The lubricated surface (LuS) is used as a substrate. Due to the mobile lubricant layer, droplets are easy to move with low friction. Surface tension is modified by adding a surfactant, and the droplet movement speed increases with decreasing surface tension. Here, this phenomenon is investigating the parameters acting to Marangoni force: contact line length and surface tension gradient. We confirm that the Marangoni force, which propels the droplet, is induced more effectively by low surface tension liquids. This study provides fundamental insights into droplet behavior governed by wettability differences, advancing droplet manipulation techniques for diverse fluidic systems.</div>","PeriodicalId":684,"journal":{"name":"Korean Journal of Chemical Engineering","volume":"42 3","pages":"529 - 536"},"PeriodicalIF":2.9,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143480873","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}

The effectiveness of the proposed piecewise RSM is demonstrated through case studies, including the optimization of tetracycline removal from water using a combined adsorption-coagulation process. This approach not only improves prediction accuracy but also integrates economic considerations into process optimization, which is crucial for industrial applications where cost-effectiveness is as important as operational efficiency.
