Recently, environmental concerns have encouraged researchers to turn more to use plant-based surfactant as cEOR agent. In the current study, the performance of the purified saponin from <em>Prosopis farcta</em> extract as a natural surfactant was evaluated for EOR applications. Initially, the validity of the purified saponin was analyzed using Fourier transform infrared spectroscopy (FTIR), thermal gravimetric analysis (TGA) and proton nuclear magnetic resonance (¹H NMR) to confirm saponin purification, thermal stability and structure integrity. Prior to EOR experimental tests, the critical micelle concentration (CMC) of the developed saponin was identified from the behavior of the electrical conductivity and surface tension results with increasing saponin’s concentrations. Thus, a surfactant solution prepared with 3000 ppm demonstrated the best performance and thus concentration was identified as saponin’s CMC point. At the same concentration, the IFT was reduced from the initial value of 29 mN/m to 6.56 mN/m and further decrease was obtained as 2.91 mN/m when NaCl was added to the solution. Meanwhile, the developed saponin at CMC range altered sandstone and carbonate rock wettability from strongly oil wet to water wet by reducing contact angles (CAs) of oil droplets to 64.57° and 44.8°, respectively. The findings of foamability and emulsification analyses exhibited that the <em>Prosopis farcta</em> saponin was capable in forming a stable foam and emulsion system. Ultimately, coreflooding test at CMC revealed that the recovery factor was enhanced by 9.65 and 11.48 % original oil in place (OOIP) from sandstone and carbonate core plugs, respectively, compared with waterflooding.</div></div>","PeriodicalId":10019,"journal":{"name":"Chemical Engineering Research & Design","volume":"218 ","pages":"Pages 438-453"},"PeriodicalIF":3.7,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143935909","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}

In the Indian scenario, most of the coal is of high ash, so it is necessary to identify and categorize them for utilizing them efficiently to the maximum possible extent. Transportation; and burning raw chunks of coal efficiently is cumbersome, so it must be converted into slurry form to overcome these problems. So far, as per our knowledge, very little work has been done on Indian high-ash coal. This study aims to identify the best of the three different Indian high-ash coals (taken from one of the most coal-rich regions of India) through various characterizations and rheological analysis. The rheological analysis of CWSs confirmed a pseudo-plastic behavior (shear thinning). 52 % CWS prepared using SJ coal showed most acceptable apparent viscosity of 250–500 mPa·s at shear rate of 100 s⁻¹ and 30 °C. Herschel–Bulkley rheological model was used to fit rheological data, showing agreement with the experiments performed. Overall results indicate that Sijua (SJ) coal, and its slurries exhibit: higher carbon content, lower ash content, greater hardness, low density, better coking properties, few oxygen-containing compounds, better viscosity, and higher pH values compared to Madhuban (MB) and Pathardih (PTD) coals and their slurries. Therefore, SJ coal was identified superior among three coals taken in this study, as it seems able to generate high energy with less residual ash while PTD coal seems least favourable for the above-mentioned characteristics.</div></div>","PeriodicalId":10019,"journal":{"name":"Chemical Engineering Research & Design","volume":"218 ","pages":"Pages 328-340"},"PeriodicalIF":3.7,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143922980","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}

The objective of this study was to determine the mean velocity following a change in the flow pattern and apparent viscosity of R32, R134a, and SF₆ hydrate slurries. We developed generalized empirical equations to estimate the mean velocity of the hydrate slurry after the flow pattern changed from homogeneous to heterogeneous as well as from heterogeneous to a moving-bed flow. The mean velocities were estimated within an error of ± 20 %. In a pseudo-homogeneous flow, the apparent viscosity of F-gas hydrate slurries with a solid fraction of 3–5 vol% was estimated to be 0.003–0.005 Pa·s, demonstrating the slurries behaved as Newtonian fluids.

Consequently, the fabrication of new materials is crucial to the eradication of FDs from aqueous solutions in a selective manner. A current study conducted a methodical investigation for optimizing the design fabricating of a novel nanocomposite membrane comprised of various zinc oxide nanoparticles (ZnO NPs) (0.05, 0.1, 0.3, 0.5, and 1 wt%) and polyethersulfone (PES) (20, 21, 22, and 23 wt%) content. Besides, determining their impact on the nano-filtration (NF) membranes performance for the FDs elimination, tartrazine AR (TZ-AR) and fast green FCF (FG-FCF). Comprehensive characterization was implemented to probe the characteristics of fabricated NF membranes. De-colorization from the water via PES and PES/ZnO membranes harnessed distinct three proposed mechanisms: wettability, electrostatic, and size exclusion. According to the results, there has been a discernible improvement in the overall performance of the ZnO-containing membranes. The rejection characteristics of FDs improved by up to 92.69 % for TZ-AR and 97.5 % for FG-FCF when harnessing ZnO content to 1 wt% in the PES membrane. However, water permeation peaked at 0.3 wt% NPs, and then began to diminish at 0.5 and 1 wt% NPs. Meanwhile, rejection surged to 96.06 % TZ-AR and 99.15 % FG-FCF when PES content was 23 wt%. Moreover, a flux recovery ratio has significantly enhanced while fouling behavior manifested a diminished compared to pure PES membranes. These results implied that optimizing the fabricated PES/ZnO nanocomposite membranes could be a viable way to impart desirable membrane traits for targeted applications with a manipulated permeation-separation trade-off.</div></div>","PeriodicalId":10019,"journal":{"name":"Chemical Engineering Research & Design","volume":"218 ","pages":"Pages 312-327"},"PeriodicalIF":3.7,"publicationDate":"2025-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143923030","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}
